Known Problems

The 2.0L TDI engine used in the Volkswagen Beetle TDI (New Beetle TDI) very commonly faces camshaft lobe wear issues causing:

-Pronounced loss of power

-Backfire through the intake (heard under the hood)

-Rough vibrations while the engine is running

-decreased fuel economy

- OBD trouble code P0101

Correction for this issue requires substantial internal engine work including replacement of the camshaft, hydraulic lifters, and possibly fuel injectors

To help avoid this issue, ensure you are using the correct oil for your engine, as listed in your owners manual. 

A dirty or failed throttle body can cause various drivability issues and illumination of the Check Engine Light.

The mass air flow (MAF) sensor may fail, resulting in drivability issues and/or illumination of the Check Engine Light.

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.

A musty odor may be noted from the heating, ventilation and AC (HVAC) system after sitting for two hours or more due to condensation in the heater case. Our technicians tell us that a cleaner is available for the heater case and the drain system should be checked for debris.

The rear brakes tend to wear out quickly; rotors may need replacement by the first brake job. Our technicians recommend that the brakes be inspected for wear regularly.

Due to an ignition component and/or engine coolant temperature sensor failure, the Check Engine Light may illuminate. Replacement of the failed component will be necessary to correct this concern.

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

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.

Reverse gear failures in the manual transmission models are common.

Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.
