Crank to exhaust cam correlation on Mini — Prince timing chain has stretched, partner code to P0016.

Mini P0017 — Crank to exhaust cam correlation on Mini — Prince timing chain has stretched, partner code to P0016. Typical UK independent garage cost: £900–£1900.

What actually causes P0017 on a Mini

P0017 on a Prince engine means chain stretch has progressed far enough to drift exhaust cam timing — past the point a solenoid clean will help. The 'death rattle' on cold start usually accompanies it. Left alone, the chain skips teeth and bends valves.

Mini engines that log P0017

• N14 1.6 turbo (Cooper S R56 2007–2010)
• N18 1.6 turbo (Cooper S 2010–2014)
• N12/N16 1.6

How we diagnose P0017 on a Mini

1. Cold-start engine — chain rattle over 3 seconds equals confirmed stretch
2. Scan tool: read both intake and exhaust cam advance errors
3. Inspect upper chain guide with borescope through oil filler if possible
4. Plan full chain kit + guides + tensioner + VANOS as one job
5. Fresh LL-04 oil and reset adaptations after work

The common misdiagnosis to avoid

If P0017 is stored alongside P0016 and chain rattle is audible, the conversation is 'chain replacement now' or 'engine rebuild in 12 months' — no middle ground.

Mini P0017 repair cost in the UK

Expect £900–£1900 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.

Bob's workshop tip

A Mini in your workshop with chain rattle and no codes is the sweet spot — replace now at £900 instead of post-failure at £2,500+.
