There's no other documentation of any major components replaced. So unsure if any other work has been done



Any recommendations of things which will soon need replacing that I need to prepare for, or get done now as preventative maintenance.



NOTE: Car is still misfiring after spark and coil change, took to BMW Dealer and had a chat with mechanic (no diagnostic) he said injectors on these models are a common fault and Ill need to replace all 6. Ive not yet replaced them however plan to do so in the next week or 2.



NOTE: Ive noticed in the past week or 2 that the suspension squeaks a bit when im getting in and out the car. Not sure if this is something to worry about?



Any advice would be much appreciated.



Cheers

Tom
