It had been bought through the eBay auction - presumably as an offer after the reserve not met - and the owner quickly listed it again after not finding anyone who could work on it.
It needs some love after sitting for what appears to be quite some time.
The engine smokes quite a bit and seems down on power even for the low power this should be producing. I have a set of new injectors and glow plugs on the way to hopefully solve that issue.
The front windows didn’t work but I was able to get them back up and running by simply cleaning the contacts on the connectors to the window regulators.
Anyway, I’m very happy with the car. I have had a lot of older Audis - but this is the oldest I’ve gotten my hands on.
From google translate:
Hallo zusammen, ich habe dieses Auto letztes Wochenende gekauft.
Es war über die eBay-Auktion gekauft worden - vermutlich als Angebot, nachdem der Mindestbetrag nicht erreicht worden war - und der Besitzer hat es schnell wieder eingestellt, nachdem er niemanden gefunden hatte, der daran arbeiten konnte.
Es braucht etwas Liebe, nachdem es scheinbar eine ganze Weile gesessen hat.
Der Motor raucht ziemlich viel und scheint selbst für die geringe Leistung, die er erzeugen sollte, an Leistung zu verlieren. Ich habe einen Satz neuer Injektoren und Glühkerzen auf dem Weg, um dieses Problem hoffentlich zu lösen.
Die vorderen Fenster funktionierten nicht, aber ich konnte sie wieder zum Laufen bringen, indem ich einfach die Kontakte an den Anschlüssen zu den Fensterhebern säuberte.
Ich bin jedenfalls sehr zufrieden mit dem Auto. Ich hatte viele ältere Audis – aber das ist der älteste, den ich in die Finger bekommen habe.
great to hear that stylish classic has got a new home at last! Cars usually don't get better from being on sale forever. Putting the aspect into consideration that you are dealing with something that is about 40 years old it is no wonder some parts need attention.
You just mentioned the injectors: It should make quite a difference to have fresh ones installed. A leaking injector can ruin not only performance but the engine itself. Check the age and condition of the timing belts, set the injection timing correctly and that's it!
Talking about the power windows one should know the design was neither simple nor bullet proof. I had one of these cars when they were new and trouble was common, got three window motors replaced on warranty then. One day the senior mechanic of the Audi dealer told me how to avoid further issues: After closing a window when you let the motor wind it up until it stops please push the button to open the window once shortly, just for a fraction of a second: Thus you relief tension from the motor and the gear and this will help prevent seizing.
On restoring my car all window motors got cleaned and the gears freshly greased, all connectors and switches got cleaned, too. From today's point of view I can say I have nay trouble with the power windows any more.
Good luck with that black beauty, keep pride in it!

I am pretty sure there is an injector issue now as the running is smoky and sounds like a bit of a knock. I’ll do the belts as well as soon as I can get my garage free. I have a 944 on the lift and a 928S to get back together - or at least the 944. It’s almost back together anyway.
I’ve half a mind to just pull the engine and just re-build it completely but that will slow things down.
Also, did a compression test while I had them out and while I found 16-20 bar impressive, it’s apparently quite a bit below the wear limit on the engine.
Looks like a full rebuild is in this engine’s future
