P0201 on Volkswagen: Causes, Symptoms and Fix Cost

Quick Answer

Safe to drive (short-term)

P0201 on a Volkswagen means the engine computer has lost electrical control of the cylinder 1 fuel injector: it sees an open circuit, a short or a resistance outside its limits on that injector's wiring. On most engines cylinder 1 sits at the crankshaft-pulley end, so that is where to start looking. A faulty connector or harness can set it just as easily as a failed injector. Wiring repairs usually cost about 65-220 EUR at a workshop, a petrol injector fitted about 100-310 EUR. VW, Audi, Skoda and SEAT apps often show this code as P020100; the last two digits are a failure-type byte.

What does P0201 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 P0201.

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 1 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 P0201 on a Volkswagen?

Beyond the generic causes listed on the main P0201 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

    : Volkswagen Golf

How to diagnose P0201 on a Volkswagen with OBD2

  1. Read the code and its freeze frame with Skanyx, then check which other codes are stored: P0301 (cylinder 1 misfire), P0261 or P0262 (cylinder 1 injector circuit low or high) and P0200 (injector circuit general) each change where you look next
  2. Find cylinder 1 before you unplug anything. On most engines it is at the crankshaft-pulley end, which on a transverse engine is the end away from the gearbox. Peugeot and Citroen engines have traditionally numbered from the flywheel end instead, so confirm with the service information for your engine
  3. Follow the injector harness to the first connector at that end. Check the locking clip, look for green corrosion or pushed-back pins, and inspect the branch where it leaves the main loom for chafing against brackets or the cam cover
  4. With the ignition off and the connector unplugged, measure across the two injector pins. Port-injection petrol injectors typically read about 12-17 ohms, while direct-injection and diesel injectors use much lower values, so compare against the figure for your engine
  5. Measure again from the ECU connector pin for injector 1 so the reading includes the harness. A good injector at the plug but an open reading at the ECU pin points to the wiring between them
  6. Swap injector 1 with injector 2, its neighbour on the same rail, clear the code and drive. If the fault moves to P0202 the injector is faulty; if P0201 comes back the wiring or ECU driver is the problem. Direct-injection injectors need new PTFE combustion seals every time they come out
  7. On common-rail diesels do not swap injectors without re-entering each injector's correction code (IMA, IQA or C2i) for its new position. That coding, and per-injector balance values, are outside generic OBD2 and need a brand tool such as Carly, OBDeleven or XENTRY, or a workshop
