Audi A3 Haldex pump replaced still not working??

[Allen254]

recently I noticed my tires would spin out during a hard launch.
took it to Audi still under warranty and well they didn't find any codes but there was a TSB for Haldex pump going out
they replaced it and changed the fluid. something repair kit on the work order.

today it started acting up again, tires burning out during medium or hard launch. Funny thing is it was working for about 2 days the car felt great agin.

what could it be?? has anyone had the same issue after they replaced pump.

For starters use VCDS or OBD 11 to prime the pump. There are a few tutorials floating around on how to do this. It is sometimes referred to as running Basic Settings.

Haldex

Pump that supplies fluid under pressure to clamp the clutch.

Electronic control unit. Controls the pump.

If the pumps already been replaced...its probably the electronic control unit.
