Hi,

I need some help on determining which ECU my car has. It's a 95 854 that I've bought 3 months ago, the manual says it either has LH-Jetronic 3.2 or Motronic 4.x. I have opened the ECU and TCU box to see if there's any convenient designation for me to read. In the box at the left there's the ECU with Bosch emblem on it but it is not written anything about the model (or I'm not able to what it says with those numbers), next to it I have the AISIN tranny control unit, and and the right most slot is empty. And on saturday when I tried to read the codes from the OBD boxes behind the right headlight I was not able to get anything at all from the A6 socket (ignition system check). As Haynes manual said that Jetronics have a seperate ignition control unit I just wondered if I had one of the Motronics with the ignition controller integrated with.

Can you help me to determine which one I have?
Is there any specific method to distinguish Jetronic from the Motronic?
Does getting no response from the A6 socket helps to say that it is not Jetronic?
One more thing the manual says only ATF quality for the power steering fluid, is it same thing as the automatic transmission fluid or something else.
Thank you very much indeed with any comments.
