Bumping my previous post. If anyone has any ideas I'd appreciate it. Cheers.
So the noise in my car...
The sound is coming form the rear driver's side (if you drive over the passenger side there's no noise).
- The sound is like the noise made when you drive over a manhole cover - sort of heavy metallic du-dum.
- The sound is made when going over bumps.
The garage had a good look at the car - taking the underside protective covers off and giving the wheels a good shake. They couldn't spot anything visibly. My OH said that they gave it a pretty thorough looking over.
We took everything out of the boot (except the spare tyre). I had a good look at the spare and found some loose bolts that I bagged up.
