Hi there, so tomorrow i'm taking my a3 in for that ecu update, there is actually a service bulletin put up by audi about it. All 06-07 A3's are suppose to get this ecu update.
My question is should i put the stock airfilter back on the car, or just leave my cold air intake.

 

Well i see no one replied but i took my a3 in with the cold air intake and it doesn't void anything. They ended up replacing the run flap motor and crank sensor. The crank sensor is in the new service bulletin so they replaced it even though nothing was wrong. So i recommend taking your A3 in and have all these things replaced under warranty because they stated that they will fail @ some point.

 

Thanks buddy for the information, I will keep this in mind.

 

Yup no prob, i'm trying to get all those little things replaced before my warranty goes in feb. If anyone see's any new Service bulletins please post them.
