Reliability, common problems and owner reviews for the Mini Hatch Cooper D (1.6 diesel). Check this before you buy used.
The Cooper D is the sensible, frugal R56 — the early cars use the PSA 1.6 diesel (DV6, shared with the Peugeot 308/Citroën C4/Ford Focus), later cars BMW's own 1.6. The DV6 brings its well-known cautions: turbo oil-feed pipe coking (the classic DV6 turbo-killer if oil slips), DPF and EGR on short trips, and the timing belt/chain depending on version. It's far less drama than the 1.6 petrol and genuinely economical; with scrupulous oil and the turbo oil-feed kept clear it's a dependable long-distance Mini. Buy on oil and turbo-feed history.
