abs, tcs, tyre pressure warning lights

[mikem449x]

Right, here is one for you.

My Altea 2.0 TDI 140

TCS light came on and stayed on a few months ago, didn't really investigate as I found it intrusive and life is better without it.

Few weeks ago the tyre pressure warning light came on, found a puncture, had it repaired, was ok for a few days then came on and wouldn't go off again.

Read on here that it might be an ABS sensor so took them out in turn, cleaned them up and replaced. Last one I looked at (typical) had a lump missing out of it. Ordered a replacement.

Fitted replacement this afternoon, now have TCS, Tyre pressure warning light AND the ABS light.

Any ideas?

Hi what faults you got in faults memory and what system is it mark 60? mark 70?
post the faults codes we may try work from there.

fault codes will come when I can get it to a garage, but then I'll know whats wrong with it anyway. Just wondered if anyone had come across this before so I know what I'm up against.

In changing the abs sensor I expected it to fix something not make it worse.

HI mikem449x,
Yes i have been before with similar symptoms as i have about 10 years expierience with seat brand as a master technician.Is hard to tel without reading the fault coodes ther is many many sensors and actuators in you vehicle which may causing the light come on dash.
Comon ones in your car g201 brake pressure sensor if obviously your system is mark60,
abs speed sensor,wheel bearing whitch has reading wheel integrated in it, g85 stering wheel position and turning speed sensor,and many many others,
So i would like advice you to read the coodes and ask i am more then happy to help.

thanks, turns out the new abs sensor was faulty, replaced it today and am looking at just the TCS light on. Fault code is G201-brake pressure sensor.

G201 is located inside the abs hydraulic unit block unfontunetly is available as whole unit with abs/esp control module and really expensive.
