Hi Looking for some advice pls, posted on General Chat but no joy as of yet. Slow manoeuvres creating a quite loud grinding sound as if pads are low but they are not. Forwards and Reverse, Main Dealer have said they believe it to be within tolerance as it’s a M model. Any guidance would be appreciated, Many Thanks

Morning Simon

Welcome to the Forum

Let's start with a few questions

1. You say a noise when carrying out slow manoeuvres, so is the noise when going lock to lock backwards and forwards. Or is it also noisy if just going forwards and backwards

2. Are Disc's and Pads standard or have they been changed

3. Are tyres correct any sign of odd wear or rubbing

4. Nothing trapped behind the back plates (I would hope a Dealer would have checked that)

5. Wheel bearings checked

6. After driving any heat in the wheel centre's and brake area

Those are the checks I would carry out myself

Hi Dave Many thanks for the welcome and pointers . All of the tyres were replaced prior to collection so can confirm there isn’t any debris between discs/pads. The tech was trying to tell me that all M models did this as it’s the compound in the pads which I have never heard of. I had a M235 before and had no issues, wheel bearings not making any significant noise while in motion either. I’m unsure if the pads/discs have been replaced with after market or not but the vehicle has only covered 9k The noise is apparent forwards and backwards with either lock on or off. I have also attached a image of their genuine OEM aero kit fitment which isn’t even flush so I think I have a fight on my hands

Hi Simon

You could check www.realoem.com put the last 7 digits of your Vin into the search box it will call up your model. Then check the Brakes section if alternate pads were offered Standard or Competition.

A neighbour has a Toyota which made a grating sound Toyota Dealer found no issue and gave a similar response blaming the Pad material. She was really worried so I jacked up her car took off the wheel and found a small stone trapped between the Dust Shield and the Brake disc hooked it out with a long screw driver no more noise.

I run Brembo pads and disc's on my E53 4.6is but standard disc's and pads on my E70 and both make no noise. So I agree as the car has covered only 9k disc's and pads are just run in, if there were a previous owner I wonder could they have specified Competition Pads ?

With the Aero kit that is quite sloppy work by the body shop I hope it's not Bonded in place

As you say depending on your Dealer you could have an uphill fight on your hands Good Luck

Dave
