Hey guys I need help, I was told that at 40,000 that the TT needs to go to the dealership to get a tune up. I called my dealership and they want to charge me 600 dollars to do it? Does anyone know what is all involved with this "tune up" or is it one of the stealerships way just to get 600 out of me? I am pretty mechanicaly inclined and know what im doing for the most part. Any info would be great thanks.

 

You do everything for the 20K and add the 40K items

 

Any suggestions on the best plugs to use on a TT?

 

Yeh, your owners manual has all your service times and what is supposed to be done.

 

If you are mostly stock.. Denso Iridium IK20 gapped to .032.

If you are chipped best bet is Denso Iridium IK22 gapped to .028.

 

XCLR8TT, what is your personal experience between the two sets of plugs?

I know with other performance cars I've had only smoothness issues when it comes to software on stock plugs.

I know of performance gaining (actually, performance releasing) when upgrading plugs when chipped; from your experience, does it make that big of a difference in our cars? Namely, the 2002 180?
