I just did the dreaded 4 wheel brake job on my 2007 e63, repacked the front wheel bearings while i was at it, and now the ABS light is on, any ideas on what might have caused this ? i was reading maybe a speed sensor ? I brought the car home and no power steering as well. Any suggestions ? tips on getting this reset and back to normal ?

 

have you disconnected your battery? Someone has said that usually resolves gremlins with errors/electronic issues...

 

Thanks E55freak, tried that last night and nothing, I am pretty sure it's one of the wheel speed sensors, if i start it up and not move it's fine no lights on, but as soon as i get get going 5-7mph the lights kick on, going to head back to the garage now and see what i can come up with....

 

Do you have a red light? I had same problem and just pressed down on the brakes as hard as I could for 2 min

 

Kind of off topic, but did you replace the entire hub or just the bearings? Got a reference to where to get the bearings themselves?

As far as ABS lights, I've had mine come on when we replaced a door for body work. They had to plug in and reset it with the computer.

 

It's a yellow light, I tried that holding down the brake for 2 minutes and nothing there.
I brought it to an indy this morning and he just got a code that the abs control module under the hood was not communicating with his reader, so he thought the module was bad, I guess that's quite common on the E55 ? and that mercedes is replacing then on the E55 at no charge. But this is a different braking system in 2007. I know it's something stupid, the reason being If i sit there at idle, the abs inactive does not come on, it's only when i hit 9-10 mph it clicks on and i get the light and lose my power steering. I checked all the speed sensors to make sure none pulled out of the clips and they all seems fine. I did get original bearing seals from the dealer, im just wondering now if they gave me the correct ones. i am looking into that now.... I guess theres magnets in them for the abs sensor.

 

Yes E55s have a 10 year warranty on SBC which was extended by MBUSA

 

it was one of the wheel bearing seals had a slight nick in it and throwing the codes, replaced the seal this morning and all is well again!!!

 

Wow!!! Really?? Any thoughts on why that would matter??
It almost sounds like something you unplugged and plugged back in made electrical contact this time. Mind, you... Good job on fixing it. Just scratching my head on cause and effect.

Enjoy your ride.
