Hello dear community! I’ve been a proud owner of a Mini Cooper S R50 (JCW Tuning Kit from factory for almost a week) bj 10.2002 136t km Last night – when I came home, I noticed a strange noise, which I don’t think was there before (know the car very little):http://vocaroo.com/i/s1xmVAIHqHXO The noise definitely comes from the engine block! unfortunately not exactly limitable.. The engine runs calmly (no speed fluctuations), and has its power. I did some research on the internet and read a lot about the control chain problem (but the R56). In my case, I can’t detect a loud rattle. Do I have to worry about this “knock” or tractor noise? And a second problem, rather incidentally: If I speed up to about 40 km/h, the front commutes slightly to the left and right (for the other occupants hardly noticeable) Evtl important: it is a Bilstein b12 coilover suspension installed and set quite low I am happy about every tip! PS: I’m not a mechanic – and as far as Mini is concerned a layman at all Thanks
