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.

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

1. On 2.0 TFSI, pull and inspect HPFP cam follower — replace if any wear shown
2. VCDS measuring blocks: read cam-to-crank deviation in degrees
3. On 3.0 TDI V6, listen for chain rattle on cold start and budget for replacement
4. 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

Reading P0341 on a Audi properly

A generic reader will show P0341 and nothing else. What matters is the freeze-frame data stored with it — engine speed, load, coolant temperature and fuel trims at the moment the fault was logged — plus whether any other module on the Audi has logged something at the same time. Codes rarely arrive alone, and the order they were stored in usually points at which one is the cause and which are the consequences.

Clearing P0341 without fixing it

Erasing the code resets the Audi's readiness monitors as well as the light. The fault returns on the next drive cycle if the cause is still there, and in the meantime the incomplete monitors can stop the car passing an emissions check. After a genuine repair, the car is driven until the relevant monitor completes before it is handed back.

If P0341 is showing on your Audi, bring any scan results with you — we will read the live data ourselves, confirm which cause it actually is, and price the repair before any work starts.
