exige92 0 Report post Posted March 23, 2013 Ok went out to a double header of football two games in hot weather and gave the car a bit of a thrash. Out of town pre season trip and a b road rumble is a better explaination. Due to the fact my good mate and bimmer driver was keen to see a bit of power laid down to get the blood flowing . So that was all fine nothing to crazy tyre still in tack got home had a few needed maccas to slip back into reality...(preseason game today making 3 for the weekend) so started the bimmer up and sounded like a hole in the exaust (just got new warrent 3 days ago) so pretty sure its quite tidy underneath. So from memory took a 90deg right hander (last corner before home) foot flat and then roller up to home. This moring raspy eng sound till i decided to undo last night and threw her hard left. Sound seemed to come right. So hope the story has not bored anyone. But I'm thinking bushes or something else that i should be looking at to make this more fun. On memeory last time i gave it a good blow out straight line simalar things happendno corners. now my mind is considering that it could be eng management from exaust sensor....... opinions please Thanks in advance.

Sounds like exaust leak on start up. While driving with accelerator down sounds metalic. no bad sounds when at idle. It has passed now seem back to normal.......

slybma 38 Report post Posted March 24, 2013 i had a similar problem in my e38 740, heavy cornering caused a weird exhaust noise it turned out to be a partially collapsed muffler part came loose and moved under heavy cornering. was a good excuse to build a new exhaust system Quote Share this post Link to post Share on other sites

Could be a catalytic converter calapsing, will have to wait and see. Quote Share this post Link to post Share on other sites
