Hi,

I guess it IS one of these 1-cent-repairs. Fortunately Audi had an eye on guys like us when engineering the ECUs in late 80s, as they also provided a raw and simple "blink-out" errorcode reading for their fault memories. You just have to connect a 12V lamp to two specific pins at the error readout plug console, and it "morses" the error codes just straight forward towards you

Now the only problem is that I don't know precisely how to blinkout the ECU, but I'm sure others will reply here and tell you how to do that (and save 200.- bucks). In the meanwhile consult this one:

... and return with the codes you retrieved.

But for heaven's sake keep the 200 bucks and be patient!
