Cylinder 1 contribution/balance fault on VAG diesel — injector wear on 1.9/2.0 TDI PD and CR engines.
Volkswagen P0263 — Cylinder 1 contribution/balance fault on VAG diesel — injector wear on 1.9/2.0 TDI PD and CR engines. Typical UK independent garage cost: £220–£1800.
What actually causes P0263 on a Volkswagen
P0263 reports cylinder 1 producing less torque than peers — on PD engines it's typically a worn injector camshaft lobe or the injector itself. On CR engines it's an injector flow imbalance — the ECU's IMA codes guide the replacement.
Volkswagen engines that log P0263
- 1.9 TDI PD BKC/BXE
- 2.0 TDI PD BKD/BMM
- 2.0 TDI CR CFFB/CBAB
How we diagnose P0263 on a Volkswagen
- Read injector correction values for all cylinders
- Inspect cam lobes on PD via cam cover (or borescope)
- Swap injectors 1↔3 and see if fault follows
- Code in new IMA values on CR after injector replacement
The common misdiagnosis to avoid
PD injectors that test 'okay' on a bench can still under-deliver under load — always include a 4-gas analyser test under road load before refitting.
Volkswagen P0263 repair cost in the UK
Expect £220–£1800 including parts and labour at an independent garage. Main-dealer quotes on Volkswagen are usually higher for the same job, and the spread exists because the cheap cause and the expensive cause throw the same code — pay for the diagnosis before you pay for parts.
Bob's workshop tip
PD TDI P0263 + visible lobe wear = injector AND cam — never do one without the other or the new injector destroys itself.
Codes usually seen alongside P0263 on Volkswagen

- P0089
Symptoms drivers report with P0263
- Rough idling that feels like the engine is trying to jump out of the bonnet.
- A distinct 'chuff-chuff' sound from the top of the engine (common on PSA engines).
- The car 'kangaroos' or stutters when you're light on the throttle at 30mph.
- Massive puff of grey smoke when you first boot it onto a dual carriageway.
- The car goes into 'Limp Home' mode the second you try to overtake a tractor.
Repairs that clear P0263
- Compression test
- Injector test
- Spark inspection
