Mechanic Thinks Engine Computer Failed on 93 Passat

I posted this on the wrong forum at first. I included a kind reply
from that forum:

I have a 93 4-speed manual 2 litre. It started bucking, and my
mechanic thought it was the coolant sensor. He tried a new one, but
that did not help. He thinks it's the engine computer. I asked him
what else it could be, and he said only the wiring.

The car starts, but dies. I have to crank it in first a few times,
then sort of pop the clutch and rev it to get it going. He took the
sensor out, and at least the bucking stopped.


Any ideas? Does anyone know of a reliable source for a used or rebuilt
EC box?


Engine computer :
BOSCH # is 0261200874
VW # is 8A0907404J
VIN WVW ZZZ 312 PE 09 1221

"Computers rarely fail and to just replace it because he can't figure
it
out is a reflection on your mechanic.

Ask him if he reset the computer after he replaced replace the ECT.
I am pretty sure a reset is required to clear the error and have the
car run right again.


A good tech should be able to tell why the car runs like crap.
Or maybe he just wants you to know you need a new computer and all
he'll do is reset the one you have. I'd find a new mechanic.


Also, this is the aircooled forum (we're into bugs, buses, ghias, etc)
You might have more success asking this question in the
rec.autos.makers.vw.watercooled group.


Or better yet, get an old aircooled VW and you won't have to worry
about a computer failing. :) You'd be more than welcome to join us.

Another person suggested that I might have water in my engine, but my
car does not buck with the sensor out. It's just difficult to start
and to move for the first few hundred yards. Once it goes, it goes
fine.

I would appreciate any suggestions.

Thanks :)
