Awesome! The 4.2L is an excellent engine and is used in several models for many years. I have nothing but good things to say of the S4 4.2L cars I have driven and maintained.

hey K04-S4,

My car is in good shape, i haven't had any problems - but remember, my engine was swapped for a 07 model, and all the problems seemed to be fixed by then. It might be worth taking it into audi to have them test if there are oil leaks - i remember reading they can figure this out somehow... =)...

My 2007 S4 Avant never burned a drop of oil over the approx 2 years I owned it (it was from the US). With respect to importing a vehicle, provided you understand the costs to get one over the border as well as the potential to lose a bit on resale if the purchaser prefers a CDN car, it can be a win win situation. There are many more available south of the 49th making it possible to get a car exactly how you like it and save some money at the same time. One point to note, driving an S4 with a US cluster can get you into trouble as the car feels like you're doing under 50 kph when the speedo reads 50 MPH.

haha stevelev, that's so true

What is the actual difference between the 2004 and 2007 S4 4.2L engine?

Audi Dealer $ervice can get expensive and there are other options.

early B6 models (early build 2004 model year specifically) are full of surprises. I'd avoid them, personally and try to step up to a 2005 or 2005.5 if you can. There are deals out there.

The oil burning can be a number of things. If it's like a quart every 600-1500 miles, you've got a problem and don't want to touch the car.

Not to promote another forum here, but consider reading up over on EUROADDICTION.NET in the B6/7 S4/RS4 section. It's the best collection of information and owners of the 4.2 S4 platforms and will surely yield enough information for you.

sakimano

no real differences. There are a couple of mounting/boltup differences, but they're identical where it matters.

the platform is a bit different...obviously the body, but there are a bunch of technical improvements in the later B7 cars that the B6/early B7 didn't get.

sakimano

none. just VAGCOM activation of your daytime running lights (which takes 3 minutes and can be free if you know someone with VAGCOM)

K04-S4

Agreed
