I need help with my audi s3 a problem I keep having

[Eladox]

Hi, its my first time posting on this as I need help with my s3. I purchased myself a audi s3 2015 stage 1 which I love. When I first got it last year in november during the winter i realized that the traction control light kept going off when I press on the gas and it actually felt slower. I could sometimes hear my wheels slip which weird. For example I raced against my brother bmw 328i and got destroyed as my car felt like delayed. Now that its summer i got new summer tires with rims that are just awesome and im still having this same issue that i was having before so its not the tires. any help would be awesome so i can figure this out and have this car ready for the summer. thank you

Haldex all the time when you get the light up like this. The car should know by the temperature and grip level if there is snow or ice around. Get the Haldex serviced or the pump replaced. 20k miles is the service interval for these, if you want to avoid problems.
