Difference between 2000 and 2001.5 S4

[Frizo]

I'm interested to know whats the differences between the two.. I seen a 2000 6 speed S4 posted for sale but noticed someone saying if it were a 2001.5 they would be all over it. TIA!

[The_Jerbel]

I prefer the '00 myself. No ESP.

2001.5 is exactly 1.5 years younger than a 2000..

But seriously, the "major" differences are the intake manifold/y-pipe, turbo oil lines were said to be "upgraded" or routed correctly, no f-hose and the badges were changed. And of course they added ESP for 2001. Really nothing that major.

2000 models weigh close to 200 pounds less too! 2000's rock man!

[S4 in_lowplaces]

2001 weights 2001lbs, and the 2000 wieghts 2000lbs.Did i get it right?

[The_Jerbel]

Almost

[Jesse S.]

One has more bugs than the other.

2001.5 has ESP, Its a HUGE pain in the ass to hit the button to turn it off requiring not only the lifting of an arm, but extention of an index finger, so most people prefer the pre 2001.5 cars. The other problem with the 2001.5 and newer cars, is they they dont have the aluminum uprights, according to many on this forum and audiworld, the 2001.5 cars are in the range of 400-600 lbs heavier due to this very reason.

Interesting.. Thanks for that bit of info! I just picked up a 2000 which is why I was asking, should be here next week.. woot! woot!

[2ndEngineS4]

The 2000 has the old school S gansta emblems. It's like sleeper status A4 on roids.

[GQ//S4]

My fav part of having the '00 is the weight advantage. Aluminum uprights and -ESP = WIN!

[1997gtx]

I'll take my super rare and unique 2002 ... With my ESP for the winter, Better oil lines, etc. for the turbo's, and better symmetry in the year number for coolness.

Okay, I may have made the last one up.

steel uprights = rusted pinch bolt

ESP = no fun, it is not possible to completely turn off ESP, FYI

the only thing 01.5 has is the better manifold, cooler badges, oh and i guess the hitachi sensor

[1997gtx]

Steel Uprights = More support
ESP = "Fun" / "Safe" for winter. Doesn't hinder 1/4 mile runs

Agreed on Intake Manifold, Badges and MAF... I think we also got an upgraded TBB.

In order to fully disable ESP, fuse #42 must be pulled from the main fuse panel between the driver side door and the side of the console. This disables power to the ESP hydraulic pump.

Which is correct??

The MAF and oil lines are the pieces that I REALLY wish had come on the 00.... The badges are admittedly sweet as well, but not nearly as big of a deal.... or are they....

[1997gtx]

LoL

I judge an Audi owner by the badge on the car.

Not sure about you.
--Adam

[The_Jerbel]

Steel Uprights = More RUST
ESP = "Less driver control" and "predictability". Doesn't hinder 1/4 mile runs

Agreed on Intake Manifold, Badges and MAF... We also got an upgraded TBB, part number ending in "T".

There ya go buddy, I fixed your statement for you

Everybody makes such a big fuss about the oil lines. My original turbos went 160k miles before I pulled them out to go stage 3. They were still running strong...

[ThirdStrike]

i dont think s4's should have esp. sure its nice if you are being dumb and breaking in a fast turn but its quattro people. learn how to drive :-P
op; 2000's have different maf's (bosch vs hitachi), emblems, ecu, no esp....annnd i cant remember what else....

LoL ... Always gotta be that guy, don't ya

Exactly...

Plus is there any real proof about the oil lines anyway? According to the link on S4wiki it says:

Note: It is a common misconception that 2001.5 introduced updated oil lines. There is no conclusive evidence of this.

I have heard from other places too that the oil lines were just a made up change.

[Frizo]

Wow.. Thanks again and glad I bought a 2000!

[S-Power]

Whats the weight diff again?

00 s4 is 3350? and 01.5+ is 3600 ?

Sorry man, I'm just being a smart a$$

[The_Jerbel]

Nope, there certainly is not. There definitely is no evidence that I'm aware of that indicates that turbos from '01 and up cars last longer because of the "upgraded" oil lines...

[KryptoniK01]

After looking at the intake manifold comparison LINK from the wiki page, I was surprised to see that my 2001 08/00 build date car has the updated intake manifold.

I have noticed a lot of differences between the 2000 2001 2001.5 from just working on them. My brother has the 2000 s4 and I have a 2001.5 . My buddy has a 2001 a6 2.7t and all of them have tons of really small differences that we have noticed when using the other cars for comparisons or a reference. Even thought the cars didn't really change that much from 2000-2002 its pretty neat how many small differences there really are.

It's typical of audi(maybe others too). There are a few well documented changes between the years and other subtle things that aren't consistent on the later model cars. They probably have a surplus of parts and use whatever is available during manufacturing.

[awdjunkies]

Great Thread guys. I too am in the market (In a few months) for an S4 and yes I have been reading controversial info regarding "Which S4 is better." Of course due to the info stated above, regarding the TBB, DVs, Oil Lines, and ESP changes made to the latter S4's, Doesn't everyone upgrade these parts anyways when modifying?

[RogueStatus]

haha i have the "upgraded" oil lines and my turbos went at 52k miles

[SoEvoL]

Audi changes stuff all the time, there is like 4 different 4.2 V8s out now, Audi like to run a engine package for a few years dump it and try something new. Within that engines life span it might go through many subtle changes that most average ppl dont know but tuners and technicians will from working on them. The test track cars we get are crazy, some have engines that arn't offered, special color combos, different exhaust setups, different ecu/inj packages and more.

seriously, the oil lines on the 2000 are fine. this is almost like folklore, theres no evidence that they cause any problems. Ive had ko4's on those lines for 10,000+ miles, and with very hard driving/ Full throttle blasts at least 13 times an outing, and no problems.
