2008 Seat Leon ABS Problem

Postby imulholl on Sat Oct 22, 2011 1:29 pm


I have a 2008 Seat Leon 1.4 Petrol. Yesterday morning when I started the car I got a number of warning lights on the dash that seem to be all linked to the ABS. The ABS light, Power Steering Light and Engine light were on; the speedometer is not working; about 5 seconds after starting the parking brake light begins flashing, something that continues while you drive; and the fuel guage is not responding correctly. I have plugged it in to a general code reader and the codes I come up with are:

U0121 - Data bus, anit-lock braking system (ABS) control module - no communication
P0686 - Engine Control (EC) relay - circuit low (ECM/PCM)

Anyone have any ideas
