Hi guys,
Bit of a lurker here so firstly, apologies for not posting more often!! Just developed a problem with my car so thought I'd ask here as there is a huge amount of knowledge!
Right...I have a 130i M-Sport with ~ 35k miles on the clock, which is an 06 plate. I've owned the car for @9 months without a problem, and it has FSH.
I was driving today at around 40mph and turned a left corner to the sound of what can only be described as when you're a kid and put paper between the spokes of your wheels - a horrible sound like a gear being stripped. The sound appeared to be coming from the rear passenger side wheel but I now think it's more in the middle of the rear of the car.
The sound doesn't happen at all when I accelerate (at any speed/gear) and doesn't happen much when I brake...BUT...when I downchange, holy moly the sound is gut churning. Weirdly, the car is driving fine but there is something seriously wrong!
So far I've jacked it up and looked underneath and can't find anything that shouldn't be there (Mechanical Engineer with a love for cars, so know a *little* bit.) Is there anything you guys can think of that it could be? Due to the fact it happens on down changes I figure it must be something thats susceptible to loading like some part of the diff or perhaps the C.V. Joint?
The car is booked into BMW for a WEEK FRIDAY (!!) under warranty and I'm really hoping that the warranty will cover it, as I'm skinted at the moment saving for a wedding!
If anyone can shine some light onto what they think it *could* be and what I should check I would be most grateful. Plus I have to drive it to work at the moment, which I am not happy about!!
Cheers,
Matt.
