ESC and TPMS Fault

[cws508828]

So the ESC and TMPS fault lights came on in my 2015 A3 Quatro the other day as I started accelerating from a stop sign. I have had new tires put on since then, but the lights are still on. With the recent snow, it seems like the AWD is not working, only the front wheels are driving the vehicle. Any ideas what it could be?

Has the haldex been serviced?

Also could be an abs wheel speed sensor fault causing it all not to work

Easiest way to diagnose is through OBDEleven amd live data.

Or if you have G Meter on on your car see if it has froze or not. When my haldex stopped working my G Meter also stopped ironically.

Speaking from experience, a fault with an ABS wheel sensor will indeed cause ESC to go offline, but it will also give you a message that ABS is offline.

Any idea what live data I would need to pull to work out what sensor it is that has failed ?
