November 30, 20204 yr I am considering buying a M135i 2014 model with 77k on the clock. does this model need a timing belt change at a certain mileage?
November 30, 20204 yr Hi Dave The M135i has a timing chain not a belt. The chain is cunningly positioned at the back of the engine I have read that changing just the chain is around £1000 These engines also have a reputation for being noisy due to the direct injection, plenty of go though. Service history is paramount I would say I would do the research though remember these sites generally have posts about issues what tends to be missed is people check how many where sold in that model against the number of issues. Good Luck and Enjoy if you buy Dave
