Johnny D 0 Report post Posted October 14, 2009 Hi Guys, I wonder if anyone can help. I seem to get a whirring/humming noise coming from one or both of the back wheels of my 2003 320i M-Sport. It's got some pretty fat tires at the back (245/40/17s) which are Conti Sport Contacts. I've only had the car a couple of months and when I bought it, it was dead quiet to drive. I'm the first owner since it left Japan though. So now when I start off, up to about 70 or 80km I hear this whirring noise. I'm hoping it's the tyres and not the bearings, but I have yet to jack it up and shake the tyre as I think you'd do to check each bearing. Seems strange that it's just developed over the last few weeks when it's been in NZ tho. Maybe the tyrs arent right for this country? Anyone had the same problem or got any suggestions? Cheers, John Quote Share this post Link to post Share on other sites

Thanks for the advice! Edited October 14, 2009 by Johnny D Quote Share this post Link to post Share on other sites
zenetti 0 Report post Posted October 14, 2009 (edited) The tyres are more than likely scalloped which will give you the humming noise. It is probably at it's worst at low speed braking. Pop in and see us if you like and we can give you a definite answer. Our store is in Penrose, cheers. Edited October 14, 2009 by zenetti Quote Share this post Link to post Share on other sites

Johnny D 0 Report post Posted October 14, 2009 Ok, as bad a joke as that was, it did make me chuckle, thanks Paul! Maybe it's my bad singing in the car that's causing them to hum! Quote Share this post Link to post Share on other sites

Just wondering as well - can you rate a Remus aftermarket cat back exhaust? A mate mentioned they were pretty good, but I'm dead terrified of having a car which just drones everywhere, no matter what spead you're going!! Especially if it's a $1300 outlay!

westy 614 Report post Posted October 14, 2009 We had a Remus rear muffler on the 2001 330. It droned under 1500rpm badly enough for us to have the standard muffler welded back on. Not sure if the cat back would be similar. Quote Share this post Link to post Share on other sites

Not sure if the cat back would be similar. Dam, that's a bit of a dissapointment then. I love the car, but it would be awesome to hear a bit more of the six under the bonnet. Bit more research is needed I guess. Saying that I'm not going on spending mega bucks to get one from the states or wherever. Quote Share this post Link to post Share on other sites

Similar one on trademe: http://www.trademe.co.nz/Trade-Me-Motors/C...n-247496730.htm Thanks Peter. Do you have any probs with the air / fuel mix? I heard that the cones let in too much air for the E46 and it's better just to get the flat panel K&N filter? Supposed to give you a few extra kw's too I hear as yours does, I'm sure.
