Known Problems

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.

Symptoms include illumination of the check engine light, engine running roughly, and loss of power. Engine codes associated may be P0300, P0301, P0302, P0303, P0304, P0087, P1093 and P2293.

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 water pump may fail resulting in engine overheating and possible timing belt damage. Overheating and/or timing belt failure can result in very expensive engine repairs. As a precaution, it is recommended to inspect the timing belt and water pump at regular intervals.

Our technicians recommend having the constant velocity (CV) boots and CV joints inspected at each service. Servicing torn CV boots early can prevent the need to replace the CV half shaft or CV joint.

A problem with the torque converter can cause the Check Engine Light to illuminate.

Check Engine Light illumination can be related to a catalytic converter fault. Our technicians tell us a re-flash of the ECM may correct the concern. If not, replacement of the catalytic converter may be required.

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.

Engine oil leaks are common from the valve cover gaskets and camshaft chain tensioner gasket.

An ignition coil or spark plug may fail unexpectedly resulting in an engine misfire and possible illumination of the Check Engine Light. Vehicles equipped with spark plug wires may also develop a misfire caused by a failed spark plug wire.

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.

Extensive transmission damage can occur in some of the automatic transmission models when the transmission oil cooler fails and allows coolant to mix with the automatic transmission fluid.
