P0202 on Volkswagen: Causes, Symptoms and Fix Cost

Quick Answer

Safe to drive (short-term)

P0202 on a Volkswagen is set when the engine control unit sees an electrical fault in the cylinder 2 injector circuit: an open wire, a short or a coil resistance it does not expect. Cylinder 2 is the second cylinder in from the pulley end on most inline engines, and on a V engine it can sit on either bank depending on the maker. A connector or wiring fault typically costs 65-220 EUR at a workshop to fix; a petrol injector fitted costs about 100-310 EUR.

What does P0202 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 P0202.

Volkswagen Golf

2004-2024

On TSI petrol Golfs the injector connectors sit close to the cylinder head and the locking clips become brittle with heat, causing intermittent cylinder 2 faults. On TDI diesel models the common-rail injectors are far more expensive and replacement usually means the workshop must read and write the injector quantity-correction (IMA/coding) values with a VAG tool, which generic OBD2 cannot do.

What causes P0202 on a Volkswagen?

Beyond the generic causes listed on the main P0202 page, these are the patterns noted for Volkswagen models:

  • Brittle injector connector clip on TSI petrol engines

    : Volkswagen Golf

  • Common-rail injector failure on TDI requiring quantity-correction coding

How to diagnose P0202 on a Volkswagen with OBD2

  1. Confirm P0202 with Skanyx and note the freeze frame. A matching P0302 means cylinder 2 is actually misfiring; P0264 or P0265 narrows the fault to the control circuit being low or high
  2. Count to cylinder 2. On most inline engines it is the second cylinder from the pulley end, between cylinders 1 and 3. On a V6 or V8 it depends on the maker: engines numbered one bank first (Ford, Audi) put it on bank 1, engines that alternate sides (GM V8s, Toyota's 2GR V6) put it on bank 2
  3. Check the cylinder 2 injector plug: it sits in the middle of the rail, close to the plugs for cylinders 1 and 3, so make sure it is fully latched and was not swapped or left half-seated after earlier work
  4. Unplug the connector and measure the injector coil. Compare with the specification for your engine rather than a generic figure, because port, direct-injection and diesel injectors differ widely
  5. Back-probe the harness from the injector plug to the ECU pin for injector 2, flexing the loom as you go to catch an intermittent break
  6. Swap injector 2 with injector 1 or 3, clear the code and test again. If the code becomes P0201 or P0203, replace the injector; if P0202 stays, repair the wiring or have the ECU driver checked
  7. Direct-injection injectors are fired with a high opening voltage and piezo diesel injectors with far more, so never probe them with a test light or touch the terminals with the engine running

How much does P0202 cost to fix on a Volkswagen? (EUR)

Estimated repair costs for P0202 in EUR, compiled across makes. Expect Volkswagen parts and labour towards the upper end of each range.
