A shiny one, probably made by Bosch in Germany.



I'm assuming your trying to buy a chip of some sort? If so, your gonna have to bite the bullet and look. Your car "most likely" has one kind of DME in it, but with production year changes and the fact the thing is almost 20 years old, who knows whats actually in there.

Best bet would be to undo the plastic thing above your open glovebox and you'll see the ECU bolted to the roof of the enclosure. All you have to do is crane your next upside down and copy the number, there may be a few # sequences but it shiould eitehr end in 173, 525, etc.. It's quite simple and a 5 min job.

I would do that instead of blindly trusting someone with your same year and model, who knows what happens with these kind of things not being all uniform....
