Applies to the PRINCE engine found in: MINI One, Cooper, Cooper S, and Clubman models (2006–2014) with the 1.4 or 1.6-litre petrol engine — including R56, R55, R57, R58, and R59 variants, as well as the BMW 1 Series E87 and E88 petrol models.
Do You Hear a Rattle on Cold Start?
If your MINI petrol engine rattles on startup — especially when cold — the timing chain is likely stretched, or the tensioner has failed. This is a known issue on the N12, N13, N14, N16 and N18 engines. BMW later revised the design after widespread failures.
Common Symptoms of a Worn Timing Chain
- Rattle on cold start (sounds like a diesel)
- Engine warning light or timing correlation faults
- Engine flutters and stalled at junctions
- Poor performance or lag under load
