E46 2001 abs pump/controller fault

Postby petrolhead023 » Wed, 22 Dec 2010 22:13:15 UTC

Hello

I recently had the asc/abs lights stay on and have taken to a specialist to have the fault diagnosed. The fault is with the pump/controller.

Anyone removed one of these before?

Looks pretty easy, 2 securing bolts, one plug and the metal hoses.
Tempted to removed myself and send to BBA for a repair, refit myself, and bleed.

Have you tried it before and had any problems?

Apparently not.

I have just done a search for "abs pump fault" which drew a blank :?

If, as you say, you have taken it to a specialist and they have diagnosed the problem/solution, then I would be tempted to go down that route.

Got to be cheaper than buying a new unit.

needed a new unit , bmw quoted 2000 he ended up having it done through a friend and part from germany for 1000
first off the traction, abs and handbrake light came on
then his speedo stopped working

It's been diagnosed as most likely to be an ecu fault and not the pump.

I have a decision to make of either removing the unit and sending it of for repair, if the repair fails it'll be a second hand unit that will need to be coded to the car.

If the repair works I can do it myself for £150, a second hand unit will be £110 plus specialist time for coding (which can fail......).



So, nobody has experience of this before.....


It'll be a guess then.

That to me, sounds like you are talking about the pump :?:

Pump and controller apear to be one piece, controller is on the side of the pump.

Not sure if the controller can be removed on it's own though, I'll give it a month and have a look.

I purchased a second hand model on ebay with the correct part number, had the local specialist fit it and code it to my car.
Pump cost £65
Fitting and cosing cost £160

Sorted.

Get fault diagnosed by a specialist before doing anything though, it could just be a sensor fault, initial check also cost me £40.

Yes, that should have read 'fitting and coding cost £160'.
