Any brake fluid left in it ::)

First job should be to replace the brake fluid with new, and bleed the brakes and clutch (assuming hydraulic) :y

So to answer you question... Yes, pretty straight forward :y

Is this the car that had it's CD of 0.30 etched onto the rear quarterlight?

I think that those audi's didn't have a vacuum brake servo but hydraulic pump assisted braking,can be expensive to sort :-\

Assuming the clutch release is working (but see previous post about hydraulics :() it is very likely that the friction plate has rusted onto the flywheel.

I have done this (without causing damage) others may disagree....

Find enough space so you can drive round in circles, start engine, let it warm up. Stop engine, put it in gear (1st or 2nd), handbrake off, press clutch pedal and start engine. Drive slowly, round and round, with clutch fully depressed and alternate light throttle / closed throttle (nothing brutal) until the clutch frees itself.

Don't expect fantastic brakes at any time with these.

Worked for me too a few times over the years :y

Can you not do something similar by getting the driven wheels in the air[car on axle stands]putting in gear and starting engine and dumping the clutch?

Thanks for the replies. Brake fluid reservoir is full.Can't see anything etched on the rear quarterlight, the car is totally covered in dust you could call it a barn find.Don't know about the hydraulic pump.When first started the injectors were tapping loudly after 10/15 mins quietened down engine now runs sweet. The gear lever seems to engage as normal but nothing happens.One good thing no need to replace sills or arches.

If the brake fluid is unknown be prudent to change it regardless :y Bleeding the fresh fluid through might help with the rest of it :-\

You probably have the only one left in the UK. Bear in mind the early VAG cars did not run on unleaded petrol. From memory I think VW was the last manufacturer to go unleaded.

BL/Austin Rover/Rover were late to the party too

I've long since forgotten what the car was or who it was that owned it. I know that I drove the car around HMS Caledonia one week end after the owner had said he was going to strip the gearbox/clutch to sort it. A couple of laps of 'fixed' it!  :y  :y  :y :y  :y

Yep, but not as late as a VW  :y Especially as BL went down the road of lean burn engines first. Strange how that seems to be coming back, or so I have heard, but no proof just hear say/
