RS4 interesting tidbits

bahaha… 155,000 miles before any major maintenance

19,000 mile service intervals is pretty nutty too. What makes them come up with such precise numbers?

^19k miles is pretty close to 30k kms

who the fuck waits 19,000 miles/30,571 kms for an oil change???

Next tidbit - even though they’re 19x9.0" and an aggressive offset with lots of material at ET29, with 14 spokes (7x2), the stock wheels only weigh 27 lbs

There is not a chance that I would wait the 19000 miles between services.

Here’s some fun one(s) I didn’t realize until I opened the mini tool kit in the trunk:

  1. There’s giant tweezers that make removing the lug nut covers a breeze. I removed them twice tediously before realizing there was a tool in the trunk for this specific task.
  2. Also in that same little tool kit is a nice wheel stud (plastic). It will help you line up your wheel during installation and keep the spacers (if you have them) in place too. Nice little addition to the tool kit imo. I recommend picking up some metal ones (4 of them if you have a lift or can get all four corners off the ground at the same time at home) for longevitiy and peace of mind.
  3. We can hang our trunk carpet cover thing on the weather stripping of the trunk. This allows you hands free access to the stuff below your trunk carpet without having to worry about holding the cover up yourself.

Just thought of another mini non technical one but still helpful…
Rear tail light bulb replacement or the entire tail light assembly if needed. I love this easy to access part Audi created. The bolt is located behind a plastic cover on the inside of the trunk where the trunk itself closes. I can take a picture if needed. I love that it is so easily accesible and quick to do. One cover, one bolt and you have access.

Saki - I think the idea behind the limited throttle in the low gears in conjunction with the tq limiter were implemented by Audi for two reasons:

  1. Protect the drive train by reducing or limiting drive train shock which would also help prevent premature wear.
  2. Keep the driving experience refined.

This is just a guess but both seem logical to me.

Our self leveling headlight system is neat too. Those blue little end link looking bits at all four corners tell the car where to aim the headlights based on the angle of each corner etc.

I have all those on my car, they are nice little features. The plastic wheel hanger is pretty useless, i need to buy some metal ones

Yeah I wasn’t sure which cars came with what tol kits and what was in each so this aparently is not unique to the RS line.

yeah, I’ve heard those before but they don’t really add up to me. How about you?

This isn’t an A4 where the majority of purchasers are like my wife who just cruises around at the speed limit. This isn’t even an S4 which is a performance variant with 300+ hp and is targeted at enthusiasts. This is a limited production RS model. This is a 'throw everything out the window…lets make it awesome." kind of car, and it’s not one where worrying about a refined (muted bitch-like) drive in 1-2-3 under 5500 rpm should be a concern.

Neither does a 1000-4000 rpm catback exhaust restriction way back there just 12" from the tips. All around those two things confuse the heack out of me as an RS4 owner. So does the lame little neckdown at the end of the downpipes to 2.35". I mean they put a frigging aluminium hood on it. They revved it to 8250 rpms. Why are they restricting the car?

And never mind the fact that it’s an RS…but there’s even a sport version of the Renn Sport. The Sport button. Even with it depressed, there’s still no full throttle control in 1-2-3.

The only explanation I can think of (other than the wear/tear thing you mentioned) is that they knew they were going to use this engine in the R8 and the RS5 (and B8 RS4 Avant), and knew they’d need to leave a little headroom.

As George’s JHM tuned/full exhaust RS4 showed this fall, running 12.2 @ 112 vs. 13.0 @ 106 stock, they certainly did leave themselves headroom for the next models using the engine.

Found this regarding the B6/B7 S4 -

It also utilized a strengthened alloy crankshaft bedplate for the five main bearings, and a two-part baffled oil sump,

This should be a standard wet sump system (std oil pan) no? Unless this is not accurate, it looks like us lesser 4.2’s are also baffled, but not sure to what extent in comparison to the RS4 or if this is even the same thing.

sounds similar but less complicated. Not sure what the design is like. I’ll try to dig up what the RS4 has…it’s pretty cool.
p.s. ‘lesser 4.2s’ lol. Not so fast. They’re all awesome. If someone said that about my B7 S4 I’d have slapped them!

Cool piece of engineering…

Where did you dig up that pic

Very nice find there. And yeah, I can call it lesser since I still have one. You’ve upgraded and the post was directed at you. Agree though, I freakin love my car and have wondered over the years if it was really worth it to upgrade down the road. With the help of this thread, I’m beginning to see that it is.

+1 Saki for posting that page. I was planning on sharing this page this evening but you beat me to it. Edit* Not well stated and could be confusing. Main point was, it’s a good design.

This is all from the RS4 study guide. A PDF that has been circulating the forums for a while now. Too bad we can’t get our hands on one for all platforms.

My thought is more leaning towards preventing/limiting driveline shock. You made some valid points - this indeed is the limited production “RS” model which should be in theory Audi’s version of “let’s go balls out for those who want it.” I guess we won’t know for sure unless we had acces to the designers who created it and asked them. Unless someone can dig up an article that covers this aspect of the car.

I would love to get one for the 3.0

yeah, I was just joking my man. ;D

Cool…that’s just me wishing I had an RS4.
