The flywheel for the 2006-2008 Volkswagen Passat with the 2.0L Turbo engine is a non-conventional "Dual Mass" flywheel. It is known to make light rattling noise when the engine is cold, and should subside once the engine temperature raises. If the rattle doesn't go away when the engine warms, the flywheel may have failed.
If the dual mass flywheel has failed, the only solution is to replace the flywheel.
This engine (2.0L FSI) uses direct injection which requires very high fuel pressure. This high fuel pressure is achieved by using a high pressure mechanical fuel pump (HPFP) that is driven off of the camshaft.
The HPFP may fail due to damage from a camshaft manufacturing defect. The defect causes abnormal wear of the mechanical barrier between the camshaft and the fuel pump. This barrier, the cam follower, will wear down and cause failure of the camshaft and the HPFP.
To correct this issue one or all of the following will need replacement: the camshaft, high-pressure fuel pump, and/or the cam follower.
To help prevent this issue from occurring, the cam follower should be inspected every 10,000 - 15,000 miles.
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.
The digital display portion of the instrument cluster may fail. Our technicians tell us the entire instrument cluster will need to be replaced to correct this concern.
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.
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.
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.
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.
