Audi however dont use Haldex on their big power cars, they use a mechanical diff (I think a plate type) on the S6, RS6 and RS4. Not sure on the RS3.

Thanks guys for Your input.
What about the 2.0 XWD itself and amount of mods it can stand with this setup ? Are there any users here who could tell something about modding these cars and differences to FWD ?


I've got 2010 9-3 2.00T xwd. Stage 3 with do88 intercooler. . Excellent power with good fuel economy, not to mention the superb handling.

heyes, that's interesting.
Tell us more about this stage 3 on xwd. For how long You've had it? Is it still ok? What numbers stand for this tune, around 280bhp ? Or more?

That's because the original Quattro was permanent 4WD which was in turn based largely on the Ferguson Formula set-up, as used in the mid-60s Jensen FF.

Audi uses Haldex in the smaller cars mainly due to efficiency considerations, and also to share platforms with other VAG products. Most people won't gain much from "proper" 4WD over Haldex, although it does at least work in reverse...which can occasionally be useful in very slippery conditions!

Like lots of 4WD systems, Quattro is very understeery, unless you have the very expensive Quattro Sport rear diff which makes your Audi much more chuckable :wink:
My old B8.5 S4 had the diff and compared with equivalent cars I drove without was a completely different beast. The reason I bought the S6 was partly that finding a newer B9 S4 with the diff was nigh on impossible whereas the S6 comes with it as standard, plus I had to have a V8 in my life at some point... :lol: :twisted:

Sorry for the thread hijack, I'm not turning into an Audi fanboi, honest! :roll:

A few years ago I was hankering for some kind of AWD, road tested quite a few and tried out a few friends cars, the 9-3 2.0 sportwagon I test drove, was OK, I was slightly underwhelmed and expected more, the Turbo X was marginally better...…..to cut a long story short I bought a '00 Evo VI Tommi Mak, then I bought another :lol:

I can see there are really few people that have moded XWD among us. Personally I'd go and buy one over a FWD as I know fwd limits after tune (terrible wheelspin around 300bhp), but there is so few people who could say anything about all wheel drive on saabs that it makes me think it's for a reason.. ;)
BTW, is this exactly the same drivetrain as in TurboX ? If yes, it should at least handle 300KM/400NM accordingly...am I right?

I was thinking the same. We have a 2.8 litre XWD. It's fine, if serviced correctly. The drive train is much the same. The only thing that may be missing is the electronic LSD, which was an extra.

The "weak spot" is the Haldex differential at the back. It got a bad reputation because said that is was sealed for life. It started failing at around 35,000 miles, and you would be charged £3750plus fitting for a new one by Saab. Then Saab said that you had to change the fluid every 35,000 miles. Then they said that you should also remove the side panel and clean out and change the filter. This solved most issues.

Since then the aftermarket has sorted it. You still do the above, but there are extras that can be done. You can remove the opposite cover and clean the hydraulic pump. A bit of time and a gasket, against £875 for a new pump...

If you have a serious problem, the Haldex can be rebuilt. It would now be done with modified parts that are used on the Vauxhall insignia and used for rallying. Around £1200.

Sgould thanks, it's a lot of helpful info in this field but I'm still trying to figure out if we can mod 2.0 with XWD, and how much it can stand.
The main thing I've been wondering and cannot understand - according to BSR site there're less tune possibilies for 2.0 XWD. You can't go further than stage 2 (388NM), while on normal 2.0 FWD BSR offers stage 3 and 420NM, so at first glance it's the drivetrain that makes the difference.
On the other hand, TurboX which has same XWD system that 2.0 has, is able to handle 488NM. I know that bigger numbers are due to different engine mainly, but it's clearly visible that Haldex doesn't seem to be a problem here. Am I missing something here? Just my thoughts ;)

have a look at the Saab TurboX Club Facebook page. There are some guys on there who have done big power on those cars. If they are fussy about your car being "only" a 2.0. Try the Facebook page for "ALL SAAB". Nathan (Nate on here) has done some TurboX tuning in the past.

https://www.facebook.com/groups/7926878257/

https://www.facebook.com/groups/allsaab/

I'm not sure of the differences in the tuning. It might be something to do with the exhaust. The routing may be compromised because the XWD propshaft is in the way. Don't know though. The 2.8 exhaust leaves the turbo on the top left hand side of the car, not down the back, like the 2.0

Perhaps the weak spot is the clutch on the b207 xwd version?

As already said the XWD drivetrain can do 300bhp+ as shown by the 2.8 cars.

Unsure on the B207 2.0litre engine.

But I know the clutch on the 2.8XWD cars is different (larger than the fwd cars by 10mm) to account for the clutch getting a harder life as no wheel spin to ease torque load.

XWD is always automatic?
TurboX is not, what about 2.0 ?

Our XWD is a 6 speed auto. The box is rated at 450Nm.

I think it was standard on the auto 2.0 Aero XWD, The others got a 5 speed auto.

No, you can get manual 2.0 xwd cars.

I expressed myself badly there...

You can indeed get manual XWD cars. I was trying to explain that a 6 speed auto was also available on the 2.0 XWD. Most other non-manual cars got a 5 speed auto.

So is there anyone who owns a tuned 2.0 XWD?
