Do you have a quattro?

A bit confused when you say wheel spin
Just that if you dont have quattro i cant see why your getting wheel spin unless your reving high and trying to pull away . If i defintely had no esp build into car just remove the switch and replace with a blank

You do understand a vehicle does not need to be 4 wheel drive to have ESP right? His vehicle has got ESP intact all A3s do.

It’s a braking function - it doesn’t provide positive torque to the wheel via a driveshaft it only uses the brake callipers on each of the wheels to stop the wheel as per system demand

The reason I asked if it was quattro is because when the Haldex controller under the car becomes faulty, the TCS and ESP are turned off.
The car then becomes front wheel drive and will spin up the wheels far easier, as well as not having the above safety features.

If you don't have quattro then you can rule out a faulty Haldex controller. Ideally you need to get it fault scanned as there will be a logged fault to help you identify the issue.

Common problem is the button isn’t properly plugged into the connector or the latch is snapped
- pull it out using a credit card and seat the cable.

Confirm if holding it for 3 seconds does anything now with the engine running


Btw has someone done a facelift DIN conversion on your car changing the button, the connector differs so maybe just left it disconnected.
