P0335 on Volkswagen: Causes, Symptoms and Fix Cost

Quick Answer

Not safe to drive

P0335 on a Volkswagen means the engine control unit is not receiving a valid signal from the crankshaft position sensor. This sensor tells the ECU where the crankshaft is in its rotation, which is essential for fuel injection and ignition timing. Without it, the engine may not start or may stall unexpectedly. VW, Audi, Skoda and SEAT apps often show this code as P033500; the last two digits are a failure-type byte.

What does P0335 mean on a Volkswagen?

The Quick Answer above is the generic definition. What follows is the model-specific detail for the Volkswagen models that log P0335.

Volkswagen Golf

2003-2024

On the 1.9 TDI (ALH/BEW) and 2.0 TDI (BKD/CBDB) engines, the crankshaft position sensor is located on the gearbox bellhousing. Oil leaks from the rear main seal can contaminate the sensor. The EA888 petrol engine sensor is more accessible on the front of the block.

What causes P0335 on a Volkswagen?

Beyond the generic causes listed on the main P0335 page, these are the patterns noted for Volkswagen models:

  • Oil contamination from rear main seal leak on TDI engines

    : Volkswagen Golf

  • Wiring chafe near exhaust manifold on EA888 engines

How to diagnose P0335 on a Volkswagen with OBD2

  1. Connect a scanner and check for the P0335 code along with any companion codes such as P0336 (range/performance) or P0340 (camshaft sensor)
  2. Inspect the crankshaft position sensor connector for corrosion, oil contamination, or loose pins. Clean and re-seat the connector
  3. Test the sensor output with a multimeter. For a Hall-effect sensor, check for 5V reference, ground, and signal. For a magnetic sensor, measure resistance (typically 200-2000 ohms depending on the make)
  4. Inspect the wiring harness from the sensor to the ECU for chafing, breaks, or heat damage. Pay attention to areas near the exhaust
  5. If the sensor and wiring test good, inspect the reluctor ring on the crankshaft pulley for missing teeth, cracks, or debris
