Advanced Driver-Assistance Systems (ADAS) encompass a variety of technologies designed to enhance vehicle safety and support the driver in the driving process. These systems rely on inputs from multiple data sources, including automotive imaging, LiDAR, radar, image processing, computer vision, and in-car networking. ADAS aims to automate, adapt, and enhance vehicle systems for safety and better driving. By reducing human error, which accounts for a significant number of road accidents, ADAS significantly improves driver safety. 

In adapting ADAS for Australia, factors such as local road conditions, traffic rules, and driving behaviour must be considered. For example, ADAS functionalities can be customised to handle Australia's unique wildlife crossing alerts, accommodate left-hand traffic rules, and adjust to the specific speed limit regulations and road signs in the country.  

1. Adaptive Cruise Control (ACC): This system adjusts the vehicle's speed to maintain a safe distance from the vehicle ahead. It uses radar or LiDAR sensors to monitor the distance and relative speed of the vehicles ahead, automatically adjusting the cruising speed to maintain a predetermined gap. 

2. Lane Keeping Assist (LKA): LKA helps prevent unintended lane departures by gently steering the vehicle back into its lane if it detects an inadvertent lane departure without the indicators being used. 

3. Automatic Emergency Braking (AEB): This critical safety feature detects an impending collision with another vehicle or an obstacle and automatically applies the brakes if the driver does not respond in time, thereby reducing the severity of the collision or avoiding it altogether. 

4. Traffic Sign Recognition (TSR): By utilising camera systems to detect and read road signs, TSR keeps the driver informed about the current speed limits, no-entry signs, and other relevant traffic rules, directly on the vehicle’s display. 

5. Blind Spot Detection (BSD): Sensors monitor areas around and behind the car that the driver cannot easily see. If another vehicle is detected in the blind spot, a warning signal is triggered, advising the driver not to change lanes. 

1. Sensor Malfunction: Dirt, mud, or snow can obstruct sensors, leading to incorrect readings or system failure. Regular cleaning and occasional recalibration, especially after incidents affecting sensor alignment (like minor collisions), are necessary. 

2. System Misinterpretation: ADAS can sometimes misinterpret road signs or markings, especially in adverse weather conditions or with worn-out road paint. Ongoing system updates and calibrations can help minimise misinterpretations. 

3. Calibration Issues After Repairs: After windscreen replacements or collision repairs, ADAS sensors and cameras might require recalibration to function correctly. Failure to recalibrate can lead to inaccurate system functioning, endangering safety. 

4. Over-reliance by Drivers: There's a risk that drivers become overly reliant on ADAS, potentially leading to reduced attention and readiness to take over when needed. Education and awareness on the limitations of ADAS are crucial. 

5. Interference from Aftermarket Products: Installing aftermarket products like dashcams or window tints can interfere with the ADAS sensors and cameras. It's essential to consult professionals before adding any aftermarket products to ensure they don't affect the ADAS functionalities. 

5 Problems which can cause faults in ADAS Technology:

Diagnosis of these problems typically involves using specialised diagnostic tools to read error codes from the vehicle's onboard computer. Dealerships and specialised auto repair shops like D & D Mechanical & 4WD in Goolwa being a member of the NexDrive programme can perform recalibration, which often requires proprietary software and equipment specific to the vehicle's make and model. This process ensures that all ADAS sensors and cameras are accurately aligned and functioning as intended.

Keeping your tyres in excellent condition is one of the simplest—and most important—ways to stay safe on the road. At D & D Mechanical & 4WD in Goolwa, we help drivers get the most out of their tyres with expert advice, quality products, and professional servicing. Whether you drive a passenger car, SUV, 4WD, hybrid or electric vehicle, understanding how your tyres work can save you money and improve performance.

Not all tyres are created equal. Different vehicles place different demands on tyres:

Understanding Tyre Differences Across Vehicle Types

Passenger Vehicles
Designed for comfort, low noise and fuel efficiency. These tyres typically have smoother tread patterns and softer rubber compounds.

SUVs
Built for a balance of on-road comfort and light off-road capability. SUV tyres often have reinforced sidewalls and deeper tread for added durability.

4WDs
Designed for rugged terrain, with aggressive tread patterns for traction on dirt, sand and mud. These tyres are tougher but can wear faster on sealed roads if not maintained properly.

Hybrid & Electric Vehicles (EVs)
These vehicles are heavier due to battery weight and deliver instant torque. They require tyres with low rolling resistance and stronger construction to handle the load and improve energy efficiency.

At D & D Mechanical & 4WD, we stock a wide range of tyre brands, types and sizes—including trusted names like MICHELIN and BFGoodrich—ensuring the right fit for your vehicle and driving style.

Correct tyre pressure is essential for safety and performance. Incorrect pressure can lead to:

Why Tyre Pressure Matters More Than You Think

Uneven tyre wear (edges or centre wearing out prematurely)

Reduced fuel economy (more resistance = higher fuel consumption)

Regular pressure checks—especially before long trips or temperature changes—help extend tyre life and keep your vehicle running efficiently.

In wet conditions around Goolwa, tyre tread plays a crucial role in dispersing water and maintaining grip.

Worn tyres increase the risk of aquaplaning

Reduced tread means longer braking distances

Legal minimum tread depth in Australia is 1.5mm, but replacing tyres earlier improves safety

Tyre care goes beyond just the rubber itself. Supporting services are essential:

Wheel Alignment, Balancing & Rotation Explained

Wheel Alignment
Ensures your wheels are correctly angled. Poor alignment causes uneven wear and pulling to one side.

Wheel Balancing
Eliminates vibrations by evenly distributing weight across the wheel and tyre.

Tyre Rotation
Moving tyres between positions helps them wear evenly, extending their lifespan.

Ignoring these signs can affect other components such as suspension, steering and braking systems.

Servicing your tyres regularly at D & D Mechanical & 4WD helps:

Reduce wear on suspension and steering components

Have alignment checked annually or if handling changes

Tips to Keep Your Tyres in Great Shape & Save Fuel

Did you know that tyres lose pressure naturally over time—even without a puncture? It’s normal for tyres to lose around 1–2 PSI per month, which is why regular checks are essential.

As an independently owned Repco Authorised Service centre, D & D Mechanical & 4WD combines trusted national support with personalised local service. Whether you need new tyres, pressure checks, wheel alignment or a full inspection, our experienced team is here to help keep you safe on the road.

Roll Smooth, Drive Smart: Your Guide to Tyre Care for Every Vehicle

D & D Mechanical & 4WD are now fully trained and have access to all the latest manufacturers data of Hybrid and Electric vehicles available in Australia. 

While EV's and Hybrids are still relatively new to the Australian market there is a big push locally and worldwide to shift to this new technology. And as technology and infrastructure develops here in Australia the number of models available to choose from will increase rapidly .

An electric vehicle or EV, have a specially designed engine which runs on power stored in rechargeable batteries. EV’s must be plugged in and recharged on a regular basis to keep the vehicle running. 

Plug-in Electric - These cars runs purely on electricity and get their power when they're plugged in to charge.

(PHEVs) Plug-in Hybrid - These mainly run on electricity but also have a traditional fuel engine. If you run out of charge, the car will switch to using fuel.

Hybrid - These run mainly on fuel like petrol or diesel but also have an electric battery too, which is recharged through regenerative braking, and you can switch between using your fuel engine and using electric mode at the touch of a button.

Did you know there are generally 3 types of Electric vehicles available?

Whilst a fully electric vehicle has fewer moving parts and is lower maintenance than an internal combustion engine it still needs to be serviced and inspected just as often as any other vehicle. 

Electric vehicles hold high voltages and specific PPE, special insulated tools and training are required to service them safely due to the risk of electrical shock.

Just like with any modern vehicle, you need to choose the right workshop with qualified, trained technicians who have access to up to the minute diagnostic information and the right equipment and quality parts to service your EV.

The team at D & D Mechanical & 4WD are fully qualified to look after your hybrid or electric vehicle including:

When summer rolls around in South Australia, the open road beckons for adventure. Whether you're planning a family holiday, a scenic road trip, or towing a caravan or trailer, it’s essential to make sure your vehicle is up to the task. Long drives in the summer heat can put a strain on your car, particularly its air conditioning, radiators, and cooling systems. Overheating on the road is the last thing you want during your getaway, so taking steps to ensure your car stays cool and comfortable is vital for a stress-free journey.

A properly functioning air conditioning system is key to staying comfortable during those hot summer days. From keeping the cabin cool to improving air quality, it’s an essential part of your driving experience. Likewise, your car’s radiator and cooling system play a crucial role in preventing the engine from overheating, especially when towing heavier loads like caravans or trailers. Regular inspections and maintenance can help avoid costly breakdowns and keep your plans on track.

Air Conditioning, Radiators and Cooling Systems

Your car’s brakes are vital for maintaining control and responding effectively to sudden stops, especially when driving on unfamiliar roads or in heavier traffic often encountered during holiday seasons. Before setting off, it’s important to check for any signs of wear and tear, such as squeaking noises, reduced responsiveness, or a spongy feeling when pressing the brake pedal. Additionally, ensuring that your brake pads, rotors, and fluid are in good working order will provide peace of mind and help you avoid potential issues on the road.

Tyres, on the other hand, are the only part of your vehicle that makes direct contact with the road, so their condition significantly impacts your safety and fuel efficiency. Before your trip, inspect your tyres for adequate tread depth, uneven wear, and any visible damage, such as cracks or bulges. Tyre pressure should also be checked and adjusted according to your car manufacturer’s recommendations, particularly if you’ll be towing. Properly inflated tyres ensure better handling, improve fuel efficiency, and reduce the risk of blowouts—an especially important consideration for long stretches of highway driving.

Finally, don’t forget about your spare tyre. Verify that it’s in good condition and properly inflated, as you never know when it might be needed. Taking these steps to maintain your brakes and tyres will not only make your drive safer but also help you enjoy the journey without unnecessary interruptions.

Fluids and batteries are two essential components of your vehicle that deserve special attention before setting off on summer holidays in South Australia. Whether you’re embarking on a long road trip or towing a caravan or trailer, ensuring these elements are in excellent condition will help your car handle the demands of the journey, keeping you safe and worry-free.

Fluids are the lifeblood of your car, and neglecting them can lead to costly breakdowns. Start by checking the engine oil, which is crucial for lubricating and protecting your engine during extended drives. If the oil is dirty or nearing its replacement interval, it’s time for a change. Next, inspect the coolant, as it plays a key role in regulating engine temperature. Topping it up or replacing it if necessary can prevent overheating, especially in the scorching summer heat. Brake fluid is another critical fluid to check, as it ensures your braking system functions properly. Low or degraded brake fluid can compromise your ability to stop effectively, particularly when towing heavier loads.

Transmission fluid and power steering fluid also deserve attention, as they contribute to smooth gear changes and steering performance. Lastly, don’t forget to check your windscreen washer fluid, which can quickly run out when driving through dusty or bug-prone areas. Keeping this fluid topped up will ensure clear visibility throughout your trip.

Your car’s battery is equally important. Extreme temperatures and the added strain of running accessories like air conditioning can take a toll on its performance. Before heading off, inspect the battery terminals for corrosion and ensure they are securely connected. If your battery is more than a few years old or has been showing signs of weakness, such as slow engine cranking or dimming lights, it may be wise to have it tested or replaced to avoid an inconvenient breakdown.

Wiper blades are your first line of defense against dust, dirt, bugs, and unexpected rain. Given South Australia’s often dusty and dry conditions, combined with the possibility of summer showers, it’s essential to ensure your wipers are in good working order. Over time, wiper blades can become brittle, cracked, or unevenly worn, which reduces their effectiveness in clearing your windscreen. Replacing old or worn-out wipers before your trip can save you the frustration of streaks or poor visibility when driving through challenging conditions. Additionally, make sure your windscreen washer reservoir is full and that the nozzles are functioning correctly—this is particularly important when navigating through bug-prone regions or dusty backroads.

Lights are equally important, as they not only help you see but also make you more visible to other road users. Check all external lights on your car, including headlights, brake lights, indicators, and fog lights, to ensure they’re working correctly. Replace any blown bulbs and clean the light lenses to maximise brightness. Properly adjusted headlights are also critical, particularly if you’ll be driving at night or in rural areas with minimal street lighting. Poorly aligned lights can reduce visibility for you and cause glare for oncoming drivers.

With the right preparation, your summer road trip can be as smooth and enjoyable as possible. Start by addressing your car's cooling systems to ensure they’re in top shape for your upcoming travels. Contact the Automotive Specialists D & D Mechanical & 4WD in Goolwa today.

Ensure a safe and stress-free summer holiday by preparing your car. Book in with D & D Mechanical & 4WD for a check of your cooling systems, brakes, tyres, fluids, batteries, wipers, and lights before hitting South Australia’s open roads.

When a vehicle begins to underperform, it’s not just frustrating—it can also be a source of concern. At D & D Mechanical & 4WD in Goolwa, we pride ourselves on taking the guesswork out of car troubles and restoring our clients’ confidence in their vehicles. This case study outlines one such instance, where a misfiring engine and an unexpected discovery led to a challenging yet rewarding repair.

How D & D Mechanical & 4WD Diagnosed and Resolved a Mysterious Engine Issue

A local Goolwa resident reached out to D & D Mechanical & 4WD with complaints about their car - V6 Holden Commodore - misfiring at low revs, struggling under load while driving uphill, and experiencing cold start issues. With these symptoms, we booked the vehicle in for a comprehensive diagnostic and test service.

To kick things off, we connected our scan tool to the vehicle and retrieved the following fault codes:

We road-tested the vehicle to replicate and confirm the symptoms, cleared the codes, and re-scanned the system back at the workshop. Once the fault codes reappeared, we knew it was time for a more in-depth investigation.

After removing the spark plugs, we found them fouled with fuel, particularly on the right leading bank of the V6 engine. From there, we suspected a potential injector fault, which prompted us to remove the intake manifold for further inspection.

What we uncovered under the bonnet was more than a simple injector fault—it was a bizarre and unexpected issue. Nestled under the injector rails were two deceased rats that had set up a makeshift nest. Unfortunately, during their time there, the rodents had chewed through wiring and fuel lines, causing significant damage.

We immediately contacted our client to share the findings and discuss repair costs. The discovery of the rats prompted curiosity, but neither the client nor our team could pinpoint a reason why the rats had chosen the engine bay as their home. However, the client did mention their dog had been growling and hanging around the car in recent weeks—a clue we all pieced together in hindsight.

At D & D Mechanical & 4WD, we don’t just fix problems; we ensure vehicles leave in better condition than when they arrived. First, we removed the fuel rail and cleaned out the nest and remains of the rodents. Then, we repaired the wiring and fuel lines that had been damaged by the chewing.

Once reassembled, we performed a thorough retest and found an additional issue—a fuel leak at a pressure return hose at the end of the fuel rail. We immediately ordered a replacement hose, installed it upon arrival, and conducted further testing. With all faults resolved, we cleared the codes, completed the reassembly, and carried out a final road test to ensure the car was running perfectly.

Thanks to the meticulous work of the team at D & D Mechanical & 4WD in Goolwa, the client’s car was returned to them in peak condition. The engine misfires were resolved, the fuel system was functioning optimally, and the vehicle’s overall performance was dramatically improved.

Our client was thrilled to have their car back on the road and running better than ever. While the discovery of the rats added an unusual twist to the repair process, it was a reminder of the importance of comprehensive diagnostics and thorough repair work.

For this repair, D & D Mechanical & 4WD in Goolwa ensured that every step of the process was carried out with precision. Beyond resolving the engine misfires, we advised the client to be vigilant about signs of rodents in and around their vehicle and home. It appears that this issue can affect those living in a suburban setting and not just in rural, farming locations as you would normally expect. Parking in rodent-prone areas or near possible food sources (like bins or pet food) can increase the risk of rodent activity under the bonnet. We also recommended periodically inspecting the engine bay for any signs of nests or damage.

With the vehicle’s issues resolved and proper maintenance advice given, the client could drive away with peace of mind. At D & D Mechanical & 4WD, we don’t just repair cars; we deliver results that our clients can rely on.

If you're not sure your brake maintenance is 100% - call a professional like D & D Mechanical & 4WD without delay.

When it comes to Brake Maintenance, you should never take a risk. 

Maintaining your brakes means not waiting until they need repairs or you find they are not up to the task of stopping you safely in an emergency situation. D & D Mechanical & 4WD provide expert brake maintenance and service using quality parts, covered by our Nationwide Warranty.

Maintaining your brakes means not waiting until they need repairs but having them checked on a regular basis to help avoid any unseen or unexpected problems which might impact your ability to brake safely and efficiently should the need arise.  Regular brake maintenance allows you to feel confident in knowing that your brakes will be in good working order when you need them most.

Some things are best left to experienced mechanics and this is one of them. You should never let anyone but a qualified professional touch something as key to your safety as your braking system.

Your brake pads are a vital part of your braking system and they are a part that should never be overlooked. 

Brake pads compress against your brake rotors to create friction and this friction makes your car stop. The force necessary to halt a moving vehicle is massive and gives off a lot of heat which wears down the brake pads over time. This is why regular inspection and/or replacement of your brake pads is an integral part of good brake maintenance practices.

We offer a Free Vehicle Inspection Report with every car service. As part of our Vehicle Inspection Report we inspect the brake pads for wear and will tell you if they want replacing. We can also recommend the right pad for your driving style and conditions.

Most people are aware that it is important to keep the brake fluid level topped up, but did you know that you should also have the entire system flushed regularly to replace old brake fluid and prevent excessive moisture in the fluid? Simply because it looks clean doesn't mean it's actually in good condition. Moisture accumulating in the brake fluid is not always noticeable in a visual inspection.

D & D Mechanical & 4WD are qualified to perform a wide range of brake services and repairs using quality parts, all covered by our nationwide warranty;

At D & D Mechanical & 4WD we offer a full 65 Point Vehicle Inspection report, upon request, with every full car service which includes a written review of your brakes and more. This Vehicle Inspection Report lets you know if there is immediate or future need for repairs to your vehicle allowing you to budget in advance.

Some things are best left to the experts and this is one of them. You should never let anyone but a qualified professional like D & D Mechanical & 4WD touch something as key to your safety as your braking system
