Ok, thnx m8, just got hold of a ecu from a friend hoping to hook it up tonight to check it out. btw, any idea about the "C" Suffix, same number but ends with C, as that seem to be quite common on ebay. Also how does one disconnect the wiring-harness (the round connector) close to the distributor?, eventuelly is it common to have bad connections in that area?

On the Passat's ecu it have these numbers: BOSCH: 0261 200 469 VW: 021 906 258 seem to be the same, but it doesn't have any suffix, it's a early model ie distributor (1991/92 model). Does this mean I can use other ecu's if the number match and it got any suffixes, eventualy will the connection harness of the ecu differ too?

btw, any of you have any ideas about the ECU numbers, do they have to match 100% ? f.ex same vw number, but ending with some letter combinations, what is the differences? thnx again

hehe, I guess it was newly refilled, so I guess about 70litres.....should be plenty for 1 hour...;)

Hmm, ok, I'l check that out. Thnx. Any other ideas of what to check for would also be greatly appreciated. btw will a faulty LMM also cause the engine not to start?

Not realy a Corrado question but as the engine is the same, and I'm hopefully a corrado owner myselfe in not a such distant future I'd thought I could ask in here: I'm quite lost on this problem, my VR6 won't start now, it had some problems earlier with bad wiring ending with regular cutouts etc, but got that fixed, and the engine seemed to work ok. One night I fired it up to defrost it, it had been standing for couple of weeks then. Went inside, forgot about the car, about 1 hour later I went back out and the car had stopped. After this I haven't been able to get it started, It doesn't seem to give me sparks, pretty much all the ignition parts have been replaced, besides the distrubutor (the cap and rotor have been), I'v measured the coil according to the bentley manual, and it seem to be ok (AFAIK the resistance number in the bentley is a bit low when measuring pin 4 and 15, I'v measured 2 coils and they have same results). The car seem to crank ok, but won't fire, I'm starting to think of the ECM but not sure, the voltage in on the coil seem a *bit* lower then on the battery but it's not much. Could it be that the battery is somewhat wrecked if it can crank the engine, but not fire it?, I'v tried with a new ignition switch as well... thanks in advance. One last thing: Do the part-number of the ECM have to match 100% to work?, mine have BOSCH: 0261 200 469, VW: 021 906 258 (I'v found others for sale with same VW Number but with added leters after it, f.ex the letter C), anyone got any tips on this? It is a OBD-1 engine with distributor.

Just thought I'd give a little info on what was wrong. It turned out to be a *very* stupid little error. Apparently the screw that holds the rotor had jumped off, the rotor was hanging loosley. Put the rotor back where it should be tightened the screw, the car fired instantly....:) Thanks again for the feedback....:) Soon time to sell it so I can finaly get my hands on a C....:)

yea I know, but it usually say "no signal", this one no says "intermitent" (also it doesn't seem possible to scan this car while it's running)...:(

Not realy a Corrado Question sorry, but hope it's ok to ask anyway (as it's a VR6) Have had quite a few problems with this VR6, it's a 1991 model passat vr6. It's got a distributor, have checked the wiring and that seem fine, had trouble with this before but after I changed some wires the engine ran fine. Have changed the distributor cap, rotor, ignition leads, spark plugs. The car seem to get both fuel and ignition, still won't start. Sometimes I can hear it's about to fire, very slowely it seem like it's going to fire for about 2-3 seconds, then it drops down again. Also hear it sometimes fires in the exhaust but guess this have to do with the engine beiing flooded when I crank it so much without start. Al I get in VAG-com is the speed sensor intermitent, but have tried another one wich I think is ok, also both those sensors have the right resistance when I measure that. Also tried another ignition switch from my other B3 but still same. Anyone have any idea what this can be caused by, I'm still hoping it could be fixed but I'm about to give up on it.... The car earlier had problms with random stops (wich turned out to be due to bad grounds (atleast I think so)), and I was able to drive the car about 400 Km before it went to a stop and never started again. (Also tested with another battery and charged the normal battery). Thanks in advance. Could this be a bad ECU (if so is it possible to check it in anyway?) EDIT: Also when I measured the compression on the cylinders all seem to be very good, all within 12-13 bars. Thanks in advance!
