Mini P0341 repair cost in the UK
Expect £100–£420 including parts and labour at an independent garage. Main-dealer quotes on Mini 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.

Codes usually seen alongside P0341 on Mini
- P0340
- P0011
- P0016
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
