I have an 05 on-star A8. I am looking for anything to customize it - especially:

1) chipping or performance upgrades. I love my car but I should of gotten the W12 (though it is a bit pricey). I need more power. GIAC and APR don't make A8 mods unfortunately.
2) I hate on-star and should of waited for the bluetooth. Any way of adding it so it's like stock?
3) Any way of converting the built-in phone jack for a Samsung i500 or Treo (not the v60 that they supply)

Thanks

Trade your car in and get what you want the W12. If you can afford it?

The W12 is outta reach but the new V10 looks good. However all this is now moot.

The D3 A8 developed a leak while I was driving. Long story short, the water leaked into the floor board and fried the electronics. After the dealer quoted me over $9000 to fix it I almost passed out. Since the car is nearly new, I expected Audi to cover this under warranty since it was a design flaw (water got backed up from under the windshield wipers from normal driving). They balked and I am starting a class action against Audi.

It's unbelievable after some research how common this problem affects Audis and VW's.

I'm going to avoid these cars like the plague until the situation is corrected.

More info to follow on this topic...

That happened to me but the local dealer called the district to get permission to fix the car under warranty and they did. You have to keep your COWL absoulutely clean to avoid water retention and backup. There is an article on the forum that outlines how to clear the clog do a search and you will find it.
