Electronic Stability Problem after changing brakes

[Pigsfoot]

Hi, I have an 2011 A1 that was bought as a Cat S due to front passenger wish bone and wing damage. I replaced those parts and while at it i also replaced all brake discs, calipers and pads all round. I had to also replace the rear passenger disk plate as it fell apart when i replaced the caliper. When doing this i damaged the speed sensor so have also replaced that.

 

Now when testing the drive ( car is all up on axle stands ) the Electronic Stability Problem ( ESP ) light comes on and restricts the revs. I'm presuming its an ABS / Speed sensor issue. The front passenger brake pad ( inside one ) also has a wire from the brake pad which i have no idea where it plugs into ( maybe its for a different model ) so have left it for now.

 

Any idea's on where / how to work out whats wrong. I'm presuming it has to be something to do with the front wheels as they are the only ones moving

Definitely sounds like an abs sensor or wiring. I'd recommend a diagnostic check to see if any fault codes flag up

Hey @Steve Q thanks for the response. Turns out it was because the car was on Axel stands and all four wheels have to be turning or the ESP "thinks" you are in a skid. I put all the wheels back on, dropped it on the ground and it hasn't happened since 👍

Glad you got sorted. That makes sense, you get the same when the car goes on a rolling road
