Premature wear in various multi-link suspension components can cause noises that are difficult to diagnose. Worn suspension parts can also cause uneven tire wear and create steering alignment problems.
Oil and carbon tend to build up, creating restrictions in the intake manifold. Symptoms will be loss of power (sometimes severe) and poor fuel economy.
Condensation may develop in the heater case which can cause a musty odor from the heating, ventilation and AC (HVAC) system. Our technicians tell us a cleaner is available for the heater case. Also, the drain system should be checked for debris.
The anti-lock brake system (ABS) control module may fail causing the ABS light to illuminate. Failed modules should be replaced to restore ABS operation.
Because of issues with the glow plugs and/or the glow plug wiring harness from the control relay, the Check Engine Light may illuminate. Our technicians tell us there is a service bulletin, not a recall from Volkswagen regarding replacement of the glow plugs on 2004-2005 model years only.
To ensure longevity of the engine, our technicians recommend to follow the maintenance schedule for the timing belt.
Cars using biofuel typically have problems with injection pump failures; symptoms can include a "no start" condition or external pump leaks.
Clogged sunroof drains can allow water to enter the interior and accumulate under the carpet where various control modules are mounted. Over time, the accumulated moisture can damage the control modules.
Reverse gear failures and noise in the manual transmission models are common.
Clogged drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.
