Title: Faults, with no codes
Post by: Mk1Macca on 29 June 2010, 12:38

Hi all,

A friend of mine has bought a 1.8T AUM and I have some concerns with it. I plugged in a fault code reader (my liquid) and it only came up with one fault code (to do with the coolant, a temp sender change should fix that) - despite the fact the ABS and traction control lights are on on the dash and I know when he drives it the screen mentions brake pad issues.

I cleared the code to see if it would come back, but the lights stayed on.

Anyone got any ideas?

Thanks!

Take front passenger side wheel off, and on the strut will be 2 wires, check these to make sure they havent broke, one is ABS and other Brake Pad warning sensor. Common for them to split or break

Will check, but shouldn't there be some codes being thrown up? Seeing as the dash is lit up like a Christmas tree...

Are the pads needing replaced then?  If the pad sensors are coming on, that's perhaps not considered a fault code by the ECU, just a warning message.  Same as a low coolant message doesn't throw up a fault code?  :undecided:

Did the liquid scan ALL the modules?

I'm pretty sure it did / does  :undecided:

I dont think the brake pad warning sensor runs through the ECU therefore not giving codes. Instead it lights up a seperate light on the dash.

Mine has been on since last year as i know the wire is split but its never shown a code on vagcom.
