Hi everyone, need some opinions/guidance/advice!
Firstly, chuffed to have a UK community page!
So I have a 2012 R56 (my baby) I LOVE it. Nearly at 100K miles. Recently had some bad oil leaks but all fixed (that I know of!) Also forgive me I’m not a mechanic so please go easy on part names/technical jargon! So recently noticed white puffs of smoke from the exhaust after idling at lights etc. no smell (that I could smell). Intake pipe completely in two so I’ve asked them to replace that. Does anyone have experience or advice if this is going to be a goner and dare I say not worth replacing the engine?
