Known Problems

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.

The 2009-2012 Volkswagen Jetta TDI 2,0L engine is equipped with a mechanical high pressure fuel pump (HPFP) which delivers highly pressurized fuel needed to run the clean diesel engine. This pump is know to fail at random in both new and used Jetta TDI models leaving the vehicle running very roughly, with very little power, unable to start, and/or OBD code P0087  

The most common causes of failure are fueling with gasoline or biofuel, and a factory defect in the HPFP. 

When the HPFP fails, it sends fragments of metal through the entire fuel system, necessitating replacement of every component, with exception of the gas tank. 

To help prevent this issue, ensure you are using only diesel fuel, and highly trafficked gas stations.

Additionally, Volkswagen has issued an extended warranty of 10 years/120,000 miles for this condition on select vehicles.   

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.

Electrical issues that are difficult to diagnose—and sometimes intermittent—are typically due to ground wiring issues. The most troublesome ground locations are under the battery or at the engine.

One or more power windows may fail. Our technicians tell us this is commonly due to a failed window regulator which will require replacement.
