Issues with Launch Control - Audi s3 2016

[douglascollus]

Hello everyone

I'm having problems with the launch control of my car, I'm going to post a video to illustrate the problem.

The car has no traction issues on accelerations outside of launch control.

Any idea what it might be?

Best Regards

Have you changed your haldex fluid and cleaned the screen? If the screen is clogged you'll lose the rear power or burn out your pump. If your front wheels are breaking loose then there's something definitely wrong in the rear. They can get pretty cruddy if you beat or neglect the maintenance. Pic below is not my car I change and clean mine religiously it's a 10min job.

Yes man, in my last maintenance I changed the haldex oil and the dsg oil + dsg filter.

As you said the screen was a little dirty, but nothing like the pictures above. It was cleaned during maintenance.

I have no problems with haldex on normal accelerations without using launch control. Even using ESC OFF there is no loss of traction

The situation only occurs when I use the launch control to get out with more power.

The car has no error logs in the transmission and awd systems (checked by vcds).

Hey did you ever get to the bottom of this? I similarly only experience mild traction loss during launches and not during any other types of pulls. Persists even in warm, dry conditions with rather fresh summer tires after being warmed up. It's a bit of a buzzkill because launches stock were super fun but I can't recreate the same flawless launch while tuned (I'm IE stage 1 high torque 93, with dsg tune). Haldex was serviced a month or two ago, diffs serviced, dsg serviced, everything should be fine so I'm assuming its just a beat up haldex pump (and also hoping it's just that and not the clutch packs)
