Fast forward to last week and the muffler starts making a horrendous rattle noise on cold starts. My wife has been on a 2 year tear with me on this car - she absolutely hates the muffler - her claim, it wakes her up in the mornings and is convinced our neighbors will report me for noise violations  So you can imagine her reaction to the rattles.
Took it to the dealer yesterday (Classic BMW in Plano TX) - the SA just called to say the flaps have gone bad and BMW wants to replace the entire muffler system - WTF I guess. Car will be in the shop for 5 days till they get the part in and installed. Will be interesting to see what I get back. |
I had same complaints on cold start (but mine did not rattle instead it made rattle windows at my house lol) i had to code it and remove cold start procedure.
