Here we go... I have an 04 1.8T A4. I have the stage 1 neuspeed chip in it with the Denso iridium spark plugs. I have had multiple problems since I had this stuff installed. First the coil packs went bad, so i had them replaced. When I had them replaced at the dealer they found a lot of other stuff broken, i.e. turbo boot, recirculation valve and some other things. Now the car hesitates really bad above half throttle once it hits 3000 rpms. I only run premium and have no other mods on the car. Should I have the chip removed? What else can it be?

Also, does anyone know if the neuspeed chip I have in voids the warranty?

Thanks!!!

 

Any chip will void your warranty if the dealer finds it.
The possiblities are that neuspeed gave you the wrong chip, meaning the wrong drive type manual/auto etc.
The most likely cause is you have other small engine problems, vacuum leaks, bad sensors etc. You should have the fault codes checked at autozone or buy a vag com www.ross-tech.com so you can diagnose it yourself.
