From the Aussie Tune Melbourne Workshop we share what will make your VW last the test of time.
These are the most common Volkswagen problems that our customers in Melbourne face:
The diesel particulate filter (DPF) is an essential component of the emission system, comprising the DPF filter assembly, temperature sensors, and a pressure sensor. Its primary function is to reduce harmful emissions by trapping tiny soot particles produced by diesel engines. When the DPF warning light illuminates on your Volkswagen or Audi, it typically indicates that the filter is full or blocked and needs cleaning. The vehicle can self-clean, but this process usually requires driving at speeds above 80 km/h for over 20 minutes. Frequent stop-and-go driving, short trips, or slow suburban driving prevent the system from entering self-clean mode, leading to blockages and triggering the warning light. In such cases, the vehicle may enter limp home mode with reduced engine power, necessitating professional intervention for chemical cleaning, forced cleaning using the Volkswagen/Audi diagnostic system, or DPF filter replacement.
Other factors that can cause the DPF warning light to activate include failures in the exhaust temperature and pressure sensors. Additionally, poor engine oil condition, leaking diesel fuel injectors, and malfunctioning exhaust gas recirculation valves (another emission system component) can prevent the DPF system from self-cleaning. Some models also require the fuel tank to be above the ¼ mark to initiate the cleaning process.
Throttle bodies on the Volkswagen/Audi range of vehicles can experience a range of issues which can lead to engine warning lights, poor idle, and stalling. It is common for the plate inside the throttle body to become covered/clogged up with carbon as result of engine operation. It can become clogged due to a poorly operating exhaust gas recirculation valve leading to excessive amounts of carbon flowing through the throttle body. Another issue with the throttle body can be failing position sensors inside the electronic of the unit and worn internal gears. If the issue is caused by carbon build up it can be cleaned and recalibrated, whereas electrical related issues usually require replacement.
The timing chain plays an integral part of the rotating parts within the mechanical components of the engine. The timing chain system has a similar job to a bike with the front and rear gears being connected by a chain, but unlike the bike the system on your car is monitored and adjusted by a series of sensors and actuators to make sure is stays in perfect alignment. As manufactures seek lower emission and better fuel economy components like timing chains/gears become smaller and lights to achieve this end. The natural byproduct of this is smaller lighter components a more susceptible to wear or stretching as is the case on some Audi and Volkswagen engines. As the system is monitored by the engine management system faults are usually detected and a warning light will be illuminated. Other symptoms of a stretched or poor condition timing chain system is a rattle on engine start that may disappear as the adjusters apply tension to the chain.
In our experience cooling system leaks are common from the newer style water pumps fitted to Volkswagen/Audi models. We have also seen issues with electronic thermostats, plastic coolant lines, the heater core located behind the dash, water fitting/housings and less often radiators. It is important the cooling system is in good working order as extensive engine damage can offer quickly. Check out our video below about water pumps.
DSG issues. A quick Google of Volkswagen DSG gearbox will bring up thousands of articles and complaints about the DSG transmission. The most common issue related to the brain of the system is called the mechatronic. This component is an electronically controlled hydraulic pump system which is responsible for the shifting of the gears and operation of the clutches fitted. It's a remarkable piece of engineering but does tend to be the weakest link in this transmission. Clutch wear can also be an issue with complaints around shudder being the most common. Warning lights or flashing spanners on the dash can be a sign of trouble.
One of the common issues that Volkswagen owners face is coolant leaks, which can lead to significant engine damage if not addressed promptly. Recently, we resolved a coolant leak in a Golf R, providing a clear example of our expertise and attention to detail.
In this particular case, the owner of the Golf R noticed a drop in coolant levels and a warning light on the dashboard. Upon bringing the car to Aussie Tune, our skilled technicians quickly diagnosed the issue. Using our advanced diagnostic tools, we identified the exact location of the leak. The culprit was a worn-out water pump, a common issue in many Volkswagen models.
Our team efficiently replaced the faulty water pump, ensuring that the new part met the manufacturer’s specifications. The entire process was documented in a detailed video, showcasing our methodical approach and the precision required in such repairs.
By addressing the coolant leak promptly and professionally, we were able to prevent further damage to the engine, saving the owner from potentially costly future repairs. This case reinforces the importance of regular maintenance and timely repairs, especially for high-performance models like the Golf R.
To prevent these common issues, regular maintenance is key. We recommend you get your VW checked or serviced regularly, ideally as part of your vehicle's routine maintenance schedule.
