Hi guys and girls,
This is my first post here and not one of joy!
So happily driving along the motorway and heard a loud thud. I initially thought I'd ran over a stray cone base (cones down the hard shoulder) or hit one of the UK's liberally littered pot holes!
After pulling off the motorway and checking the car over, turning the radio down and driving at town speeds I could hear a rotational flat tyre type noise. Got it to a local garage I used, they put it on the ramps and said the noise was coming from the diff, like I've chipped a tooth.
Apparently BMW won't repair it under warranty as I've not got BMW approved tyres on!
Someone has offered me a 20k diff off a 535i but I'm not sure it'll be compatible?
Any recommendations from where to purchase a 530d specific diff?
