Car is out of warranty in a couple of months.

MySD4 has developed either a bearing noise or rear diff noise

It is booked in to dealers in two weeks time, do not use it much in October for a third service - price is approx £325 I think he said, but will also change break fluid as well (extra cost), also thinking of getting them to change the transmission oil since I was towing a caravan in Austria/German alps last summer and about to do same next summer.

They will also report on transmission noise

Will get back to you when we have more details on findings.  'There is thunder' then 'There is the warble of a V8'
