2004-2006 ? - 250hp, 3.2 vr6 I'm unsure of the 3.2 engine code

Just saw this many days too late...
The NA 3.2 TT's engine code is BHE (a MKIV r32 is a BJS)

Here is a nice spec sheet for all the technical aspects of the 225 and 180's.

TT"s still has probs like this??

[zetarhopike]

Hi Eric, can you check the link to the offset calculator in post #1?
The link should contain the ending forward slash '/'; ie. "http://www.2x.ca/TT/offset/" instead of "http://www.2x.ca/TT/offset". Internet Explorer doesn't seem to care about this but Konqueror and Firefox(svn) complained about a malformed url.

I am installing a V.D.O. boost gauge in my 02 225 and using the Modshack gauge ring setup I need some help on which wire to tap for the gauge to light up and be on the dimmer. So which wire do I splice it to on the back of the headlight switch for proper function. Help !

This is not true, I have a 2001 with AWP (K03S, wideband,vvt).

[MK1QuaTTRoHaus]

Can some one explain to me about what the "revised" TT really is?? I'm not 100% sure about what exactly it is... and I ask because I do not have an asr button on my dash... I got the emergency flasher button, the 2 seat heater buttons, the rear window defogger button and that's it... I have one empty hole right in the middle. Is that where its supposed to go??

[l88m22vette]

Yes, the ASR/ESP button would go there. You also have a button between the hatch and fuel door releases, that is to turn on and off the interior motion sensor (for security), the later mk1s just dumped the button and always have the sensor on w/the system. The various updates to the TT all happened by 2003 (aside from the 3.2/DSG stuff) but I don't have hard dates for several of the changes

[MK1QuaTTRoHaus]

Oh ok for sure thanks.

Any pics of this? I thought that button was for the roadster's wind deflector (mine is blank obviously).

i have a 2003 and like uve said i dont have the motion button. but if i lock my self in the car the signal doesnt come on
does it not work? or what?

[A4 1.8 Turbo]

I think if it detects motion right off the bat, it disables the motion. i.e. like leaving a dog in the car or something.

As a TT nOOb, this is a great READ FIRST thread! thanks to all that have provided this info.

[owenxguo]

I was wondering what kind rear LSD options do I have for TT? and final drive ratio?

Thanks

[l88m22vette]

The only LSDs available are those from Quaife or Peloquin, the OEM rear diff was open. Final drive is set, though I know transmission gears from other cars can be used (Euro TDI O2M had better gear ratios)

[owenxguo]

Thanks, any limited slip available for the rear? I saw 034 has it for sale but no part# and brand, so I was curious if it's an aftermarket or oem option.

[l88m22vette]

Both companies makes front and rear diffs for the TT (planetary gear type, never seen clutched LSDs for the TT)

[chads]

I don't know much about the LSDs.

Is it possible to get both front and rear?

Or would it bee better to go with just the rear or just the front?

Because looking at this link: http://www.mjmautohaus.com/catalog/i...183_6851_11615 They have both front and rear. Kind of confused.

[wrparrish]

You seem very confused.


The front differential is installed in the transmission, as it operates and regulates the front drive axles.

The rear differential is installed in.... The rear differential / pumpkin. As it controls and regulates the rear drive axles.

On a quattro vehicle, you can have both front and rear, or just front, or just rear.
Whatever you want really.

Unless your buying a haldex controller though, i wouldnt go with the rear upgrade, as the majority of your power goes to the front anyway.

Haha i remember making this post on AZ a year ago!

Symptoms:

1. Top will not operate with the switch, only manually. Makes no sounds when trying
2. Doors will not lock or unlock with button in car or remote (keyfob is absolutely useless)
3. Trunk will not pop with remote or button
4. Windows will not go all the way up, stop about .5" short when the top is shut
5. Overhead lights dont work but everything lights up as it should when the headlights are on
6. Keyless does not work
7. No heated seats
8. etc

Fix:

First, check all fuses! Attempt to connect to module in VagCom. If no connectivity:

1. pull the passenger seat all the way forward, or you could remove it if you want to i guess
2. remove center speaker grill by gently prying around perimeter
3. remove 4 screws around speaker perimeter
4. use a wide screwdriver or something to gently pry around the center trim panel. There are 3 clips on each side, nothing at the top and nothing along the bottom. This was a pain in the ass to get free.
5. Once center panel is removed, pull passenger side panel from bottom then once the bottom is free, pull down to release the top.
6. Remove two phillips screws on trunk latch handle inside of glove box then remove the cable from the latch and set latch aside.
7. use wire cutters or needlenose with a screwdriver to remove right side gray push pin, just pry it out.
8. There is still one push pin in the back, I just pulled with increasing force until the glove box and the pin popped free.
9. This was a little difficult, but with the top up, open the passenger side access panel above the ccm and then use a 10mm socket with extension to remove the two 10mm bolts holding the top of the box. I felt these blindly and removed then blindly.
10. Go back to where the glove box was and you can see the bottom of the ccm, just pry it up and out of the bracket or remove 10mm bolts for the bottom.
11. Maneuver the freed ccm around to where you can release all of the plugs. There are 5 or so and all but 1 are a single push button release. The main black one was a little difficult with a gente pry/release on both sides.
12. Your ccm is now free!

I inspected mine and found a couple pins to have a green/blue hue to them from moisture so I pulled the unit out of its sleeve and found this.





As you can see there is water damage on the bottom of the main board and the other chip that is attached to the board is completely ruined.

For the record, my car is a 2001 225 Roadster and the PN: 8N7 962 267 A

In Europe the 3.2 can be purchased as either manual or with DSG.

Performance chips will significantly increase your horsepower and torque. They do this primarily by advancing engine timing, adjusting air/fuel ratios, and, in turbocharged vehicles, increasing boost beyond factory limits. The major tuners are APR, REVO, GIAC, Unitronic, and Eurodyne; with all of these companies you can expect to pay around $500 for a flashtune. If you plan on chipping your car and sticking to bolt-ons, the best mods to consider include a turbo-back exhaust, a TIP, a FMIC, and a nice boost controller. You will need 1-step colder plugs gapped to .028, and should at least have a boost gauge. Some other things to consider are a new diverter valve, a catch can, vacuum hose cleanup, and improved bushings and mounts.

Hey,

I'm a noob at this, though I love cars. I own a 2000 Audi TT. It's the 180q and I had to replace the turbo because it went bad a few months after I owned it (not cool). Back then I knew about the k03 and k04, but I wasn't sure if I could get a k04 and just bolt it on in place of the old k03. After reading your FAQ it looks like I could have and I ****ed up there

Anyway, I've bought a Forge DV/Splitter from TTstuff.com and a Haldex controller from HPA. I haven't installed them yet because on the 16th I'm taking my car in to get some FREE NEW SUSPENSION due to some open case against Audi right now. Also (finally) getting the glitchy gauge cluster replaced. After that, though, I'm going to install the Haldex and DV. I'm wanting to get my car's ECU flashed to get the 12psi from the turbo instead of the stock 7.8psi

I was already wanting to get a catch can, FMIC, turbo-back exhaust, boost controller and gauge, along with some lighter pulleys and a Neospeed intake system. How much strain would it put on my car to wait to get the catch can, FMIC, and exhaust if I have to wait a few months after I get it chipped? Also, what would a new TIP, vacuum hose cleanup, bushings and mounts do better for my car that you suggest I get them if I get it chipped?

Thanks

[l88m22vette]

A chip won't hurt a car, and bolting the parts on after can only help (and you'll see higher power increases vs. stock bolt-on). I think its fun to try something, and get a feel for it before throwing more stuff on

All the other stuff (TIP, mounts, vac cleanup) are smaller things that add quality more than quantity, as in feel of the car, shifting, etc. Things generally feel more solid and crisp, and this is what the Haldex controller will do as well. Skip the intake unless just for sound, the stock airbox flows plenty for the k03. I would definitely throw in a new rear sway when you do the exhaust (same time as the Haldex controller?), the controller/sway combo key.

[Chuckmeister87]

I'm actually running over to my grandfather's house right now to install my Haldex. I've had it for a month or so now just sitting at my house as I was out of town for work. He's got all the tools anyone would ever need to construct or repair anything, so I can trust he'll have the short-handled hex wrench I need for the install. (Also, thanks for the suggesting a zip-tie over a rubber band for the install.)


The TT feels rigid and planted in the turns. Does a rear swaybar really make a big difference?
(Also, thanks for the advice on all the small things that make the car feel better as you drive. I will be looking into those very soon)
