Camshaft position sensor performance on Audi — on 2.0 TFSI it's the cam follower and HPFP wear, on 3.0 TDI it's the timing chain.
Audi P0341 — Camshaft position sensor performance on Audi — on 2.0 TFSI it's the cam follower and HPFP wear, on 3.0 TDI it's the timing chain. Typical UK independent garage cost: £50–£4500.
What actually causes P0341 on a Audi
On the 2.0 TFSI EA113 P0341 typically precedes high-pressure fuel pump (HPFP) follower wear — the bucket-style cam follower wears through, then damages the cam lobe. £8 follower swap at 60,000-mile intervals avoids a £1,500 cam replacement. On 3.0 TDI V6 (rear-mounted timing chain) P0341 means chain stretch — a £4,000+ engine-out job to replace.
Audi engines that log P0341
- 2.0 TFSI EA113 (A4 B7, B8)
- 3.0 TDI V6 (A4, A6, Q5, Q7)
- 1.4 TSI
How we diagnose P0341 on a Audi
- On 2.0 TFSI, pull and inspect HPFP cam follower — replace if any wear shown
- VCDS measuring blocks: read cam-to-crank deviation in degrees
- On 3.0 TDI V6, listen for chain rattle on cold start and budget for replacement
- Replace cam sensor only after mechanical checks confirm timing is correct
The common misdiagnosis to avoid
Audi 3.0 TDI V6 owners need to budget for the rear timing chain at 80,000–120,000 miles. Don't 'just replace the cam sensor' — the chain is mechanical wear.
Audi P0341 repair cost in the UK
Expect £50–£4500 including parts and labour at an independent garage. Main-dealer quotes on Audi 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
If buying a used 3.0 TDI Audi, walk away from any with even a hint of chain rattle on cold start — it's a £3,500–£5,000 repair and pre-purchase inspections need to include it.
Codes usually seen alongside P0341 on Audi
- P0016
- P0017
- P0011
Symptoms drivers report with P0341
- Engine cranks noticeably longer than usual before catching — especially hot restarts after a shop stop
- Loud metallic rattle for the first 2–4 seconds of a cold start (the classic 'death rattle')
- Rough lumpy idle at traffic lights, sometimes stalls when you dip the clutch
- Turbo feels lazy or flat below 2,000 RPM — ECU has retarded timing to protect the valvetrain
- Stop/Start stops working (ECU disables it once cam adaptation drifts past spec)
- MPG drops 3–6 mpg with no other obvious cause
- P0011 / P0014 / P0016 / P0335 often stored alongside — that combination is chain, not sensor
Repairs that clear P0341
- Sensor replacement
- Timing chain inspection
