[s-cars] Help 95 S6 Avant ECU

[James Murray (QA/EMC)]

If the unit is throwing codes then the ECU is still alive... (if the fuse was burnt the ECU wouldn't give codes). Never heard of a code for bad ECU, although I never checked for one either. Seems too coincidental that the Cam Sensor went bad that many times... I agree however it could be something completely different, best to post your codes.

Did it die while running?, or just won't start? 
Fuel pump?
Bad POS?
Bad ignition switch?
etc?

well,

my money is w/ Emre on this one. i do not want to jump to anything  
here, but i will almost bet the 1st owner got taken a "bit". might  
not have been the tech's fault, but then again, he probably had never  
seen one of these cars or their peculiarities.

i would suspect a lot could be learned from knowing (and then  
posting) what codes were thrown exactly. could be something as simple  
as the cam sensor was installed incorrectly or it could be the fuse  
at the ECU itself. then again, it could be something altogether  
different.

will it turn over at all?
are there any other symptoms?

matt.
