People have run water/meth on their RS4's, it doesn't help.

What about running an e85 based set up, would that compliment the valve stems more efficiently than the Meth setup?![]()

A ton of misinformation in this thread.
OP, RS4's generally don't suffer from the same timing component problems that V8 S4's do. The guides/tensioners have updated parts. TBH, it was mostly 04 and 05 S4's that see most of the problems with timing components in general.
In regard to the carbon build up, its a DIY job. Or you can pay a few hundred bucks every ~10k miles to have it cleaned. JHMotorsports is supposedly testing a solution that prevents carbon build up.
Also RS4 + bolt ons =12.2 @ 111 mph 1/4 mile

A friend has one as his daily. He found the quotes to do the carbon cleaning outrageous, so he did it himself; about 5hrs. He said it wasn't difficult, but tedious.
The only other things he's mentioned are:
Brakes and replacement brake components are expensive b/c they are unique to that car (and the Gallardo I think).
OEM stock parts (wheels for instance) are really expensive and near impossible to find used.
Not much information exists for DIY projects since most owners are wealthy and they just pay other people to fix the car when it breaks.
They do sound glorious though![]()

I love the RS4 but think its outdated. The B8 S4, E9X M3 sedan or even the 335i would be cars I would check out too though the 335i are everywhere.
#43
My everyday commute would include a italian tune up.
which will segway into the next CON of the RS4.....
MPG, esp compared to a B8 3.0T S4
I've seen this happen, in other peoples lives, now its happened in mine...... <------MENew Phaeton Owner.

Not really concerned with fuel mileage. I average 15-16 with my B5, but I only fill up every 2-3 weeks.

I have a B7RS4, original owner since June 2006. So some info:
1. Carbon cleaning -- I get it done every year or two. Time consuming, but not horrible.
2. Gas Mileage -- I get 17 city / 23 highway, which is far better than the 14/19 that my friends with E90 m3's get. Although, they don't get carbon buildup.
3. Parts -- really not so bad, since many parts are shared with A4's. With the right connections, it's also pretty easy to get OEM parts at dealer cost (I do).
4. Ease of maintenance -- I find it to be pretty easy to take care of, and mine is almost 6 years old with 51,000 miles on it.
I find the car a hell of a lot more fun than the B8S4. That said, an E90 m3 is also a great choice.

+1 for the 2013 S4, ordering just started, i voted with my wallet on the 2012 S4, absolutely no regrets, all glitches, like the water pump, rear diff seal, brake squeal, clutch noise sorted out over the previous years.

who cares ^^^^, it's really not that fast for all that extra coin, that's the pickle.

Can't think of any reasons why not to buy an RS4. It's a compelling choice. Though the new B8 S4's would tempt me if the price difference were close enough.
#51
I would bypass the RS4, and just pick up a DTM S4 for way less dough.

To be fair to you, what were you trying to say? Seems like you directly said it was one of the ugliest cars on the road. Maybe you don't think it is the best, but one of the ugliest?
Where's the context we are missing?
Sorry to say, the B8 is terribly ugly, I'd go as far to say one of the ugliest cars on the road today. That picture is especially bad.... combine that with the ghetto fabulous LED DRL's.... no thanks. Maybe I'm crazy, but you know what they say about opinions.

Is it true the build up is caused by the crankcase and valve covers being vented through the intake?
unrelated question
as people mentioned the v8 s4, once the chains and tentioners have been changed, they are good for the rest of the life of the engine, as most chains are? or has the issue not been fixed with updated parts

In all honesty I think something like this may be a longer term solution than just "decarboning" every 20-30k. What about an injection system that runs essentially on demand, and injected something like an acetone/atf solution, or anything else that would help keep the intake and valves clear. Im aware water/meth wont work, but i think all it may need is something that actually dissolved the buildup.
Its fairly clear that the main issue with many DI engines is carbon buildup in the intake/valves, and unless you rip out all the emissions controls/egr, etc, Im sure this will continue to be an issue.
but back to the main question, I would say the main reason not to get it is because there are alot of cars out there that may be less "raw" but perform almost as well with less issues.
Personally I would take a 335i with a chip, and extended warrenty for the fuel pump, and call it a day. I like the RS4, but IMO the B6, and B7 chassis cars seem very dated compared to the B8, and its competition.

You like the looks of the B7 RS4 – enough to strongly consider buying one over its distinct disadvantages – but think the B8 S4 is the ugliest car on the road?
I really don't know what to say.

amazingly hyped up car with avg performance figures esp for the segment
-no faster than an e46 m3 in the straights, worse in the turns and just about everything else
-staid audi commuter sedan looks
-stupid engine placement
-what you already pointed out
