Distributor part numbers for 1991 Audi TurboQuattro 20v

Did I accidently ruin my ECM ..Ben,

Further to my being unable to start my 1991 Audi TQ 20v. I have a situation where I need advice on distributors. 

As you might recall, I went thru many different attempts to revive the car unsuccessfully.  I flatbed it to a shop who has been working on it for 4+ weeks (Northern Motorsports - Wilder, VT) .  They reached a point where after working on various issues they said I need a Hall Sensor kit p/n 1230329049 or a whole distributor Bosch p/n 0237522019 or OEM Audi p/n 034905205Q.  They stated they knew someone in Chicago that had a used correct distributor for $500. at which point I told them I would locate a distributor.

I contacted Force 5 (who specializes in used Audi parts) in Concord, NH who shipped me what they felt was the correct distributor for a 1991 Audi TurboQuattro 20v (3b engine) but the part number last digits are 2013 and not the 2019 that is needed. 

The repair shop takes the position that the distributor ending with  p/n ...2013 will enable the car to run, but that they do not know if the performance will suffer as a result of it being the wrong distributor.

Can you comment on the part numbers?
