Only some very late 1996 850s (the AWD and possibly the 2.5 NA) and x70 range had the Motronic 4.4 ecus which have OBD2 compliance (and even then its only partial compliance).

Yours will have the test unit under the bonnet AFAIK

The only diagnostic thing i have is the obd2 port next to the cig lighter

Hmmm, looks like they moved the port inside in earlier models then, but AFAIK the M4.3 ecu won't connect anyway.

Thats what i thought.Is there a way of scanning and reseting my problem through the obd2 port lol.this is long winded lol

There is a simple tester you can make up to use on the OBD port, heres the link

It should work on yours. The guide is very basic and simple, you could improve the tester by soldering the connections instead of taping them.

Sounds good mate but can i reset it

**Dangerous Dave** · Friday 28th October 2011, 23:32

Yes mate, it does the same as the under bonnet tester, just in the car.

Think these are the right codes

How would i reset the codes if i dont have buttons under the bonnet lol

You substitute the under bonnet tester for the in-car tester in the instructions, so you connect the test lead to pin 5 (as in the how-to) instead of pressing the button.

You could also try the app called torque on android along with a bluetooth obd device.
Works well at reading codes and for real time info but not sure if you can reset codes with it
