    Hey guys, this one has me bummed...wonder if there are anyone out there who can shed some light???

    - I've transplanted an M3 Evo engine with the suspension etc into a 318ti shell
    - Retained the ABS pump/ control unit etc.
    - also used M3 front suspenion and Z3M rear axle - but same part numbers for the wheel sensors so this should not be a problem.

    Like I said, my ABS light is now on permanently even though I had an auto-electrician here this afternoon to clear the fault codes. There are no problems with any of the systems...still the light remains on.

    I also changed the instrument cluster to the M3 unit (6 cylinder and oil cooler).

    I've compared the wiring diagram for the M3 and the 318ti and there are some slight differences but not sure if this matters - the M3's ABS light switches through the ABS relay, whereas the 318's is directly form the ABS control unit.

    The main thing is that the components of the ABS system is all the same to the compact's orginal setup and the ABS system does work. Tested it the old fashioned way - long downhill and lots of speed.

    Any help would be appreciated!!!

    Just another thought...could changing the instrument cluster to the M3 unit be the cause of the problem?

    i think there is some differences between the m3 cluster and the 4 cylinder cluster
    i remember RYM may have done a how to for some of the wiring but im not sure if he had the same problem
    pm him and point him the direction of this thread

    No need for the PM

    The wiring how to I did was for getting the oil temp to work gauge to work as the wiring is not in any other car for it

    I have transplanted my M3 engine into an 1992 E36 318iS and from that into a 1996 E36 325tds and the only time I have seen the ABS light appear was when the brake/clutch system had not been bled out but I had started the car to ensure it turned over. As soon as it was all bled through the light disappeared

    If you want that guide for the oil cooler then give me a shout and I shall dig it out for you

    Cheers disco and RYM, have read that how to (good work BTW!!).

    Interesting you mention the brake/ clutch oil bleed - maybe I should do this again?
    Thing is I have good brakes and clutch is fine too.

    have you checked the fluid level sensor in the brake fluid reservoir cap it could be shot and thinking there is low fluid all the time
    i had this problem with my old corrado a while ago
