ABS relay location...

Post by 1963paul » Tue 07 Nov, 2017 11:10

Anybody know where my ABS relay is ? in a 1999 2ltr Z3, before I start probing under the dash board...both my ABS and ASC lamps are on 98% of the time.... doesn't seem to be in the main fuse box under the bonnet.

I think you will be looking for a red relay for the main ABS system and a grey relay for the ABS pump, would have thought both these would be in the main fuse/relay box in the engine bay.

Yes, I thought so too, but, no. I read somewhere that they are behind the glove box or above the steering column behind the plastic under the dashboard. There is another box full of electrical gubbins, under a plastic cover, held on with 6 cross head screws, near the ( I think) the brake servo. The ECU seems to live there, but no relays.

Found this on an old thread is your fuse box like this?

Similar, mine has empty spaces where some of the relays are shown in the diagram. I’ll have a look tomorrow, I’m sure they are up under the dashboard somewhere. I thought the the relays I’m looking for would have “ABS”stamped on them, and, like you said earlier, are red and grey.
Thanks for your input 👍

Didn't get a chance to look for the relay, but it turns out to be a ABS sensor on the OS/R wheel. My local garage plugged it into there diagnostic 'puter, and that sensor had recorded 42 errors over the last couple of weeks. They removed it and cleaned it up, took it for test run, and the warning lights stayed off. I picked it up, and they came on before I left the garage forecourt!.
( the lights were off when I dropped the car off this morning). They have ordered a new one.
