I am about to get my first A4 for in about a week and i heard that the first mod i should do to my car is to chip it. However, when talking about it with my friend and which company he thinks is better to go wit for the B6 version. But then we got to the discussion about whether the chip voids the factory warrenty or not. I have a feeling that it does but i am not completely sure and what to know the real answer before i go through with all of this. If it makes any difference or not i am looking at buying an '05 A4 2.0TQ wit 42k.

It cant void your warranty unless they can prove that the chip is causing any problem related to a warranty claim. But, why would you want to risk it?? Wait until your warranty runs out.

I had the same concerns. My car is at 46K and I had it chipped anyway last Saturday.I went for APR Stage 1. I figured changing the injectors for 1+ might be a bit too much for a daily driver considering we're here in DC. Worth every penny. Of course, I'm only saying that now. Who knows, by the end of the year I might be at Stage II. :D

get 1+ and be done with it, most dealers arent smart enough to figure it out. the injectors add a lot of torque

well if the car i am going to get had a lot of miles i would just tough it out until the warrenty is no longer valid, however there are only 42k and it has the extended warrenty which means i still got 58k left on the warrenty

If you just do the basic chip you can shut it off when you want to and go back to stock. So they don't need to know. I have REVO stage 1 and can switch back to stock with the external switcher in about 1 min.

hegetting 2.0T so he cant go Stage 1+
2002-2005 is b6
2005.5+ are B7
wrong section but its koo

the chip does void the warrenty only if the chip casued the problem

ok. so two more questions then. 1.is it very common then that it is the chips themselves that actually cause the problem?
and 2. i have read a lot of things on the forum about how chipping is the first thing to do, and then i see a lot of ppl who are somewhat disappointed saying that their chip didnt work the first time or they feel like it actually hasnt done anything. is it really worth it on my part to get a chip with so much time left on the warrenty with the pontential possibility that it could be the chip that causes me a problem and i have to pay for a damage or labor costs to fix it
