just got myself a Audi TT 225bhp. totally standard. 115k on the clock and a full main dealer history. is it too risky to remap a car with 115k on it already.

I don't see why not. Is there any reason why you think you can't? I'd be tempted to say get a full service first and make sure everything is as it should be first though. But that's more precaution than 100% necessary.

Depends really. Maybe a compression check to make sure the engine's in good nick, and whatever you do to turbos to check them, would be in order.

Most reputable tuners will check over the car to make sure it's healthy.

The TT Forum will give you a lot of advice. They'll recommend VAGCHECK but each forum has there favourite and there's a lot of good tuners. AMD, Revo, Jabbasport are my favourites. My Ibiza was mapped by JS, TT by AMD and my polo by Revo.

You'll need a forge 007p diverter valve when you get the map. Also, be prepared to replace coil packs as they will fail once mapped if they've not been changed for a while. (coincidence more than anything else... Just to annoy you!).

Enjoy the TT... I really miss mine, not a praised car among drivers but it was a jack of all trades!

I'd add... Check to see if it's had a new clutch... 20+ psi of boost will ruin a worn clutch.


Enjoy the map too! It transforms the way the car feels when accelerating!!!

If you have a DSG 'box, might be worth checking the mechatronic control module, mk1 TTs tend to pop these every now and then.

Afraid I can't offer much as my TT was a V6, but I've heard that a simple chip/map will boost the output of your engine by quite a lot. Of course, if you fancy opening your wallet then you could always strap a Garrett turbo to the motor..

DSG was V6 only. So no worries there.

You will see anywhere between 260-280bhp. With a few more mods you can get close to 300bhp with out changing the turbo.

The sky is the limit though, some crazy yanks have some silly bhp from their 20vt's. I know of a couple of 500bhp 20vt's in the UK.

Like I say its my daily driver. I have no worry about the 115k on it. Only with regards to starting to tinker a bit with it. Never tinkerdd about with a high milage car before not sure of any pitfalls or best way to do it. Anyone played with a high miles car before

As others have said, I would make sure you give it a full service first including the belt.

The only thing that I'd also be thinking about is the clucth as I'd expect it to be on its way out at 115k. Depends on how its been driven in the past though.

If you do pt to relpace the clutch before tuning, then it would be worth putting something in thats better than standard in case you catch the tuning bug smile

My TT was running a map from low mileage up to over 100k miles... no problems at all.

The Bosch DV will break so you need a Forge 007p or alternative.

Go and get it booked in! It'll be fine!

Coilpacks will be covered by Audi FOC so don't worry.

With those miles whip the sump off and check the strainer is nice and clean (common fault with 1.8Ts).

Make sure Haldex oil chagnes have been done.

Invest (as above) in an uprated diverter valve.

Make sure it's running as it should (several sensors are known to be weak).

Get the damn thing mapped.

Our track car (1.8T) is on 133k and on its original clutch and turbo.

Surprised no one has mentioned the possible upgrading of brakes yet.

I would always upgrade brakes along side increasing power. Not so much a complete overhall, but upgrading disks pads etc.

Not sure what brakes the TT has standard, they might be the same as the Leon Cupra R Brembo 6 pots - if not, a set of those would sort out the stoppage biggrin

Brakes on a 225 are pretty good really, if they're in fine condition they'll be more than adequate for road use even with a remap.

I bought a new Audi TT 225 Quattro Coupe in May 2000. I’ve still got it and I’m just as ‘taken’ with it today as I was the day I collected it from Colebrook in Newcastle; more so in fact because I’ve made changes. My car was remapped in 2003 at 20,000 miles and I now have 91,000 miles on the clock; so 71,000 covered after the re-map.

AMD re-map
Viper diverter valve
Brembo brakes
Ferodo DS2500 brake pads
Thicker anti-roll bars
Koni sport adjustable dampers
Eibach sport springs
Haldex blue PP controller
Forge adjustable rear track control arms for camber correction
Rear wing extended lip spoiler (colour coded)

I’ve just done a track day at Croft Circuit with no problems and I haven’t had any serious problems over the last 11+ years. I have to say it’s been maintained fastidiously all the time I’ve owned it (mostly by myself) and a trusted race preparation mechanic who’s attention to detail is second to non. It’s been a very good buy IMO, and I have no intention of changing it.

Hope that helps

Joe

Must say I am impressed that nobody has made any of the usual negative comments about the TT, I must say that they do seem to be going from fashion led to enthusiast purchases, the shape has aged really well and they do have all these tuning options. Ok they may not be renown as the ultimte drivers car but sit in that interior and you see the point, they do feel special and with knocking on 280 bhp will be pretty quick. I think prices have about bottomed as well, cant see them ever descending into banger territory, i.e. less than a grand, think even the leggiest, sludge green TT will always be worth something so potentially fairly depreciation proof.

Neer understood why they did such lame colours when it came out though ?

You could always sell it and buy a sports car, or a hair salon.

Mine is bright silver with black leather and full interior creature comforts. I also have installed an item from Race Diagnostics, referred to as a Liquid TT gauge which gives me mountains of useful information on the move (e.g. my oil temperature went up to 125C on my Croft Track day!! That was OK because I was using Miller's Triple Ester Competition FS 5/40 engine oil, which is good for 120C all day and 150C peak).

I have also fitted a slotted gear shift gate, like the Ferrari/Lamborghini/Audi R8 etc cars have and it works beautifully.
