Volkswagen Passat Problems
RepairPal has identified the most common problems with the Volkswagen Passat based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
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.
Reverse gear failures and noise in the manual transmission models are common.
Ignition wire breakdown is common, resulting in misfires.
The parking brake may not operate correctly. The correction involves addressing any stored anti-lock brake system (ABS) fault codes, replacing the rear brake pads if required, and following the basic settings procedure as per the scan tool. Our technicians tell us these procedures must be performed in the correct order for the parking brake to function correctly.
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.
One or both head lights may not work due to premature head light bulb burnout and/or bulb harness failure. Care should be taken to inspect the head light harness connector for damage when replacing bulbs. Damaged connectors should be replaced.
Because of issues with the glow plugs and/or the glow plug wiring harness from the control relay, the Check Engine Light may illuminate.
Throttle body failure is not uncommon and can lead to shifting issues with the automatic transmission and other drivability concerns.
To ensure longevity of the engine, our technicians recommend to follow the maintenance schedule for the timing belt.
