Hi I have recently purchased my 4th Audi 80, yet another gorgeous car! But! Alas, she is poorly, there are two problems.
First problem; the power steering pump started leaking from an O-ring seal under a circular plug situated on the top of the main pump body, next to one of the hose connection unions. I removed the plug which has a large Pozi-drive type screw head and found that the O-ring was split. My local Audi garage couldn’t identify the pump let alone the seal in question so I have managed to source a couple of O-rings of near identical size. I fitted the first one and all seemed ok, no leaks and smooth power steering. After about 30 miles of driving, smoke began to pour from under the bonnet and the (!) warning light began flashing, when I stopped and looked, the seal had blown again covering the engine in power steering fluid! ARGH!!!
I replaced the seal twice more but the same thing happened each time!
Has anyone else experienced such problems? Is there some thing wrong with the power steering system or is the pump shot?
Second problem; auto gearbox. She changes up through the gears smoothly except for 3rd - 4th, under slow - medium acceleration when she changes from 3rd to 4th it is not very smooth and the revs climb quickly and then drop again as 4th is engaged. Some times she will miss out 3rd altogether and go straight from 2nd to 4th? Also, under hard acceleration, for instance joining a motorway, she'll change into 3rd and doesn't seem to want to change into 4th. Eventually, she does change into 4th but either at very high revs or after a couple of miles of steady driving?
Any ideas greatly appreciated!
Regards, Tym.
