Hi all - I purchased a 2013 m135i with ~90k km about 6 weeks ago, after putting less than 400 km on it a couple of weeks ago the car began losing power in up the rev range which gradually got worse. Initially, I assumed this was turbo related but it has developed to the car being very jumpy at idle and low revs with a clicking sound coming from the engine bay and check engine light. Any ideas on what this issue could be (ideally near Parnell)? Unsure whether it would be worth forking out for the BMW workshop or not.
