Garage took a look at it this morning, up on ramps and all seems good. No signs of overheated brake disc, and both pads look to be in good order. I took the car for another run including several sharp stops , and it seems to be working at the moment.

I am driving 144 miles from Stevenage to Blandford shortly, so lets hope it continues this way. At least once I am at home getting it sorted is easier than here.

I got back to Dorset, although I am still not convinced all is well. I did the trip in several different legs.

First was Stevenage to Watford to meet up with a friend, no smell.
Second was Watford to Winchester Services, again no smell.
Third was Winchester Services to Tesco in Blandford, again no smell.
But
Fourth was Tesco to home, about 2.5 miles across town, and I am sure there was a smell when I got home. However, the there may have been hint of oilyness in the air. perhaps the smells cause is something totally different.

Engine oil level normal, brake fluid level normal,

Maybe there is some oil sitting on the block somewhere and due to the slow drive across town then there was a build up in the engine bay, I really don't know.

Or maybe when you're doing local driving around town you're both braking more plus turning the wheel more which emphasises the binding brakes issue if it's there and underlying. it will therefore heat up quicker and smell quicker.

I still feel you need to check the calipers a bit more thoroughly. . .

Does it smell like brakes/clutch or is it a stronger, more acrid smell?

From what you've said, especially as it's on the passenger side, it may be the output flange seal on the gearbox leaking fluid onto the nearside cat.

Could be miles out though but worth a look. :Confused:

its the off (drivers) side. I may end up letting a local Blandford garage take a look, the place that did the MOT also do service and other work.

As I said probably miles out. That'll teach me to read the thread properly. Doh:hammer:

Another vote for the front driveshaft seal. The brakes do get hot on an A8, but the smell would suggest fluid leak. Mine was leaking for a while and burned off on the Cat leaving little or no evidence, which fooled everyone until we got it up on the ramp and found the leak.

Driveshaft seal will drip on cat and stink, but leave no trace until you look close :) My D2 had it, smelt like hot oil. Brakes are a very different smell.

Would I be able to see signs of a leak without getting the car up on ramps.

I don't think you can as it's above the cats (somewhere) at the back of the box (?).

If it is the seal the smell will get worse to a point where you think the car is trying to kill you :D.

It's a very distinctive smell, not like brakes or clutch.
