S4 FAQ
 

Ok, so I've been on this board for about 7 months now.

It seams like we get the same exact questions all the time. Can we sticky this?
Feel free to add your thoughts!

How long will my turbos last.
Till they blow. There is no way to tell. Boost leaks, long oil change intervals, bad DV's, lots of short trips, getting to the boost when cold, will all help kill em.

Can I use a BOV/ what DV's are the best
Yes, you can use a BOV, the car will run like SH!T, & you will get a CEL. Bosh 710n's are the best stock replacement, any other rebuildable DV's are good also.

What's a TBB
Throttle body boot, it's weak, and like to tear, causing an boost leak, will help kill turbos', there cheap & easy to replace. APR Bi-pipe will fix the problem permanently.

What intake is the best for the S4
Darintake, holes in the bottom of the air box, work the best, panel filters don't hurt, K&n's oil can kill MAF's, so use ITG, type. AWE's S-flow is ok, but don't add much for the $$
Open elements filters are dumb, unless you have a heat shield.

Is this is a good deal
If you are happy with it, then it's a great deal. All cars have different prices, just cuz I paid more of less is not a reflection of your car.

What breaks on the S4
TBB tear, DV's go out, some sensors are flakey (Bosh MAF), seat bushings wear out ($5), tie rods ends are weak. There pretty solid cars, you just need to take care of them.

What chip to get
What ever one you want! It's best to pick one up locally, so you don't have to send the ECU out. There all about $500. GIAC, APR, MTM are the most popular.

Are these cars expensive
Yes, parts are not cheap! Things will break! Timing belt is a $1000 job & needs to be done before 100,000mi. Turbo replacement is expensive due to having to pull the motor to change the turbo's. Just about every part will cost $100. If you can't afford to drop $1000 at any time on the car, walk away, or learn to wrench.

How much is insurance
More then your Mom's Honda. It's a Twin Turbo V6, you do the math. Prices are all relative to location, age, driving record. CALL YOUR INSURANCE COMANY!

Where can I find S4's for sale
Here, Audiworld, Audizine, Autotrader, local paper, eBay, craigslist. DO YOUR OWN SEARCH! If you find a car that isn't local, ask some one who is local on the board to check it out.
It's not our job to find you a car, unless you are offering money to do so.

Are Audi's hard to work on.
YES, cramped engine bay, lots of electronics, lots of one use items (clamps).

Where can I buy parts?
Dealer, ECS, PureMS,

Where to buy Mods?
AWE, ASP, MTM, APR,

What's the best mods?
Chip, best bang for the buck! (yes you should change your DV's & make sure you have no boost leaks). Next would be a Cat back, there super easy to install, and give real gains, they also help the turbo spool faster. Darintake, it's FREE!, Downpipes, piggies are cheap (gutted stock DP's) but do not flow as much as aftermarket ones. YES< they are expensive, but worth it if you want the power & fast spooling turbo's. Yes, you can JUST put on K04's. But if want max HP, you need the whole thing, fueling, intake, IC's, turbo back exhaust. Everything must work from air filter, to the tip of the exhaust.

What's a VAG-Com
It's a really cool tool that anyone who wants to work on their car should have! Dealer wants $100 to check codes, most Auto parts stores will check them for free.

RE: S4 FAQ
 

looks good to me, i approve. maybe it will stop all the noobies from asking these questions over and over and we can get back to talking about the finer things in life, like women and our cars

RE: S4 FAQ
 

2k s4, i am insulted, you didnt put me down as a place to buy parts and mods. but other than that i think this is a good sticky.;) i just started to respond to tech questions and i can honestly say im sick of hearing when my turbo's will die. also change the timing belt service to every 60k, they have broken even earlier than that.

RE: S4 FAQ
 

I was alraedy thinking sticky as i read the first sentence..

Ye ask an ye shall recieve..


Now... GET TO DA CHOPPA!!!!

RE: S4 FAQ
 

Didn't know you sold parts! Do you have a URL to add? Company name? I just put what was on top of my head down.

The timing belt.
Well, some say 60mi is over kill, some say 100kmi is to far. From my limited experience with the 2.7t, it seams to me that 70-80kmi is about the sweet spot.


Guys feel free to add your own comments, or expand on mine, lets get a good knowledge base going.

RE: S4 FAQ
 

no url yet, just got some guys to actually get started on the website this weekend but as always pm me with what you need. as far as timing belt kits go i cant beat ecs price by alot so its not really worth to compete, they buy a ton of those things at once. that seems to be the only thing they get cheaper than me though.

RE: S4 FAQ
 

great job 2k... i've noticed a reduction in non-logical questions from people with a post count below 2

RE: S4 FAQ
 

Good post; a lot of questions I had have been answered here. For a person who is a COMPLETE noob in the audi world, this will hopefully allow me to avoid flames and trolls when I post questions.

Thank you 2K S4.
