After doing hours upon hours of research on the s4 b6/7 I wanted to post on here to get some real stories, opinions and information. I've searched threads all over the place and still have yet to see one of compiled stories.
To be short and sweet, I'm looking into a 07 s4 with 85k. Seems to be a super clean car, first owner was a lease then second owner drove it for a year and put 35k on it. The car is beautiful, no real issues at all except some condensation in the headlights and very minimal oil around the valve cover.which I was told was normal.
I want to hear your real life experiences and stories with these cars, especially with higher miles. The timing chain/ guides is really what bothers me. So share your stories and try to convince me, one way or another.
Dont mind my spelling, haven't written in english in years.
I have had mine for one year now. Its a -04 b6 s4 avant. It has seen 195 000 km now and is now in good condition. It was not when i bought it. It once was a dealers show car, a "quattro tour" car. Since then previous owner didn't all threat it well. There was oil leak from valve gaskets, rust under door blades or what they are called due to poor cleaning, badly repaired small bump in rear fender scratches all over, leaking aux radiator and so on. Things that made me still buy it were milltek catback, rns-d and best part was that engine and tiptronic were in wery good condition. No weird noises exept the intake flap rattle. And it is imola yellow.
It is now been painted over, lowered, repaired fully. It has taken weeks of work and about 7 to 10 k€. Last repair was trying to remove the notorious intake flap startup rattle. And I did. I installed new flap control actuator or whatsitcalled and opened the intake and sealed it properly. Now It starts quietly.
Next mod is to change resonated milltek to non res.
I have seen only one broken main chain guide in another s4. It was making random left bank adjuster failures and they began to come more often until after two years of driving the owner wanted it to be fixed. Dealer took the engine out to chance the adjuster. it actually was broken but just to check out the timing chain they took covers off and found the broken guide. So i'm thinking thats a pretty strong engine. Imagine, two years of driving with broken main chain guide.
