    I have bought this car recently, its the 184bhp version. I like to maintain it as much as I can myself. So I was wondering how I can read the ecu and clear codes if needbe? Where is the ECU and also where is the Diagnostic plug?

    I read amongst posts a while ago that certain usb readers for VW (16pin) can be adapted to read BMW ECU's also. I have one of these VW leads, whats the proceedure??

    Thanks

    The engine ecu (DDE) is in the plastic "e-box" at the back right of the engine bay as you look at it.

    The plug on yours is either the 16 pin EOBD type that you find under the flap on the lower dash trim by the pedals, or the round type in the engine bay. If it has both you need the round one. From the age of yours I would expectthere to be an EOBD plug in the car.

    As for the VW lead... download Vag-Com I think it supports OBD2 codes.. maybe!

    I'll move this to the correct forum for you.

    The correct procedure is to install Inpa and to modify the OBD.ini to use the USB interface.

    You may need to solder pins 7+8 for comms with the E46.

    Thanks Mostly and Ian, I have VAG-COM and it has OBD checking......... in fact I think from recolection its obd2 but maybe that is backwards compatible?

    Ian when you say solder pins 7&8 what exactly is required? Just soldered together inside the plug?

    I'd see what you can connect to without first! It's a simple bit of soldering on the OBD connector.

    The vagcom lead I use is the KKL 409.1.

    you will be better using a laptop/scanner that is BMW specific, as BMW like VW have their own unique codes which are more definitive than EOBD codes.
