AI Market Summary

Direct injection engines suffer carbon build-up from 80k km—rough idle and power loss. Costly clean required.
Turbocharger wastegate rattle common on N20/N26 units; premature failure risk. Listen for noise on cold start.
Electric water pump failures typical 60k–100k km; causes overheating and coolant leaks. Budget for replacement.
Median price €27,400 is fair for market supply and age; check NCT history and service records carefully before committing.
Have independent BMW specialist inspect fuel injectors, turbo, and water pump before purchase—these are not DIY fixes.
