ECU needed for my 83 Ur
I am look for a replacement ECU (035-905-383) for my 83 Ur Quattro. Any insight on obtaining one would be greatly appreciated.

An Alternative..
If sourcing a replacement ECU *really* becomes an issue..
You can always go to a MAC 11 (MC motor 5000T).
Yes, that requires a MAC11 wiring harness, and all the related bits (air temp sensor, coil, wastegate Freq valve, knock sensor(if it'll mount to the block) and probably some other bits.
And some wiring skill, of course!
But: A much newer ECU, easier to get chips for, controls timing AND fueling (to some extent)and does 'active' wastegate control and knock sensing. A good 'all round' upgrade, as it were.
(Vs the MAC 02 that only does timng contol..!)
As much more common, can probably be obtained for a reasonable amount.
Just something to think about as an alternative..
So what is wrong with the original ECU?

Right..
Right! Of course the MAC o2 has fuel control, to do the O2 correction. I never thought of it that way. (How about the Euro version that had no 02 sensor? Did they have a FV too?)
Would this be more correct then?
"MAC11 has fuel mapping, whereas MAC02 only has fuel correction for O2 sensor"
(WX fuel enrichment is done via hoses and solenoids, throttle switches and uses the Control Pressure Regulator)

are you the guy in Dana Point?
I think my husband Craig emailed you? We're just doing car stuff this weekend if you want to pick one of ours up. Shoot us an email. Don't you have a Coupe Quattro also?
