Hi,
I missed out on the 4.2 audi I posted about earlier. So I'm back to square 1.
What I want.. 02+ audi A6 with quattro.
I have no idea which motor is the most reliable. I would ASSume the normally aspirated 6 is but who knows?
I would prefer the car have no more than 60k miles on it. I will be my daily driver. ~14k a year.
Which motor is the best on gas when cruising? How about when getting on it?

What would you pick were it you? This will be my only car for a little while so I need reliability.
I see 'has the timing belt been changed' all over this website. What intervals does this happen?

Are factory navigation/bluetooth systems available? Are they good. I do realize I can always get a tom tom or some other aftermarket unit but they never look nice and with all the red instrumentation I think anything aftermarket would look terrible. especially at night.

please help! i'd like to buy in the next week

 

Personally (I live in northern michigan with winters thinking of going to the UP for college with massive winters) I would go with the 4.2 or something not turbo.I have a 99 2.8 quattro. I just would not like the chance of a turbo failing or something when i am in 2 feet of snow trying to get home. Just reading around it seems like the turbos are a little more figity although my moms boss has a 2.7T quattro and hasn't had a problem so I suppose it is just luck of the draw.

 

Well I had a 2.8 A4 but it wasn't enough power and I needed a bigger car so I started looking at the A6's. I figured the 3.0 wasn't powerful enough and the 4.2 only come in automatics so I now have a 2.7T 6MT. I'm hoping the turbos don't fail anytime soon (23K on the clock). The NA motors will be the most reliable.

 

Yes - turbos need a little extra TLC but well within the parameters of taking care of any fine luxury sport touring car. You do have to pay attention to warm up/cool down especially and use a good synthetic motor oil. I like the option of the MT6 which may not be available on any of the other models.

Other than a massive repair bill IF the turbos fail, most of the problems I have seen posted are not engine related. They cross all A6 models: the2.8l, 2.7T, 3.0l, and 4.2l. Your advantagefor allexcept the 2.7T is that you don't have to worry about turbo failure. But they all need similar maintenance including a timing belt + other parts at 80-90k.

Not all 2.8l's come in quattro.

I've seen more posts from owners of 2.8l's looking for performance parts than I have from 2.7T owner's wanting to de-tune their ride or complaining aboiut turbo failure. The 4.2l comes with the hp right out of the box. PS - I just turned 101k with stock turbos and a GIAC chip for the last 22k miles.
