bolw off valve trouble.....
 

I install a blow off, an after 15 minutes riding, the car looses power, and the valve stop blowing like it should, why can that be_?

second problem, my esp does not work no more, how can I fix that, I did replace the brake swicth because the brake the light did not work and some body said that was the problem... but the light did not go away and the ESP still not working, I have to reset with the VAG.

Thanks a lot
