ABS light still on

[Billy Greenbush]

I have a 2003 525i Japanese import low miles 21,000

ABS light was on and diag said front right speed sensor . Also I needed a new window module passanger side

Mechanic installed sensor and window module . Light still on and code 33 then came up - Vehicle front left sensor (circuit) . He went to replace front left sensor but the computer wouldn't recognise it

He said he thinks it might be the ABS pump but can't diagnose this- he has checked wiring to the pump and it's ok

Also on the Hella window module he installed is printed "ABS" . Does this have anything to with the ABS module and how it communicates with any other systems ? The serial number on the new part is different to the original but the window, mirror and door locking mechanism are all working fine now

As far as I know it could be either. Don't think Irish cars ever got DSC.

Have never seen one manufactured after 2002 with asc to be honest but open to correction on that

If the OP decodes the VIN?

Theres no need the buttons on the dash

The traction control button, should be below the air con.
