Ok, I received mine today.and guess what? The F____ING CLOWN SENT THE WRONG ONE!!!!! I am so peeeeed right now, I feel like phoning the owner of the place right now at home, at 10pm and telling him to shoot the shop foreman and his parts guy! Alldata shows it as part # 003-153-28-28, and I got a 003-153-96-28. The connector does not come close to fitting right. I drove the car this evening first (going to the bus to pick up the new part), and it just died coming to a stop sign. Waited 10-15 minutes, away it started and got it back home in my shop. Got the new part, car started before I pulled the sensor, ended up putting the old one back in, and it doesn't start now.
Will try it in a bit, maybe it will at least flash up.
MB Doc, do you have a part # for the '99 ML320, or is the 003-153-27 (28)-28 the same thing as far as connecting it again?
