S3 wheelspin

Yes that makes sense, what used to happen behind the scenes in PFL is now selectable via the MMI in the FL so that rear bias is increased but only in certain drive modes and possibly exactly the same in dynamic if the hardware is indeed the same ?
Regarding the hardware, we're assuming that the module on the side of the diff is calling all the shots regarding how much clutch is in at any given moment. Given that that decision is made with reference to steering angle, throttle position, gear selection, relative wheel speeds, brakes, and perhaps even air temperature, perhaps the choice of 'how much' is handled elsewhere, and the diff mounted module just looks after the fairly complex task of managing the pump and clutch to deliver demanded torque transfer.

Entirely possible mate, wonder what the 5 pins of the Haldex ECU connect to ?

we update for you gents,
done the oil and filter change on the haldex but no joy and wheels still spinning :(
oil was rather black when drained and looked like it had lumps in it but on touching the lumps they just disappeared so no metal or anything to worry about.
just away to have a look for a new pump so if anyone has any info on who is best to get the pump from and cheapest that would be much appreciated.

I take it your car is out of warranty?
If so then yes your next logical step is to replace the pump..
@Rob2k68 had his done at an independant garage think the cost all in was in the region of £180. Post #76
He should be able to give you some info ...:salute:

I've had the same symptoms in my TT, turned out to the haldex pump was knackered (burnt out).

No problems with the fuses or anything like that - oil change and a new pump and its back to gripping the road again in the wet!

Did you have the car hooked up a computer/vcds and if so did it show any faults? Audi seem to be telling me if it's a pump issue there would be some record/fault code thrown up.

Same generation / issues as this on mine but mine required the pump... got one new from a company on eBay (seller name is haldexparts) only charged £159.00 all in a few months back... cheaper option for anyone who's car is out of warranty like mine.

I've had my tyres burning for some time, thought it was just my Conti5's being down to around 2mm. I waited until the 19k mile Inspection and had Pilot Sport 4's all round...I didn't mention the loss of traction as I had put it down to the worn tyres.
Fast forward 1000miles (had some bad luck in private life recently so couldn't take it in) and they've told me that it IS the Haldex Pump that's needed. They are doing it Thursday.

Thanks for starting this thread. Hopefully, I'll be able to do a normal Launch again soon. Might make me feel a bit better.

Mine is a 2010 TT - once it was fixed it changed the car. On fronts only it was dangerous to drive in my honest opinion. Pulled hard left or right into tracks in the road due to the torque going through the fronts only.

My 2014 S3 PFL has same symptoms as all previously mentioned..............Traction cutting in at anything other than a light pull away and giving it the beans meant constant traction flashing and interrupting.

Only had mine since the summer so assumed it was me getting used to power and pushing her harder but after a good drive out in the Peak District yesterday realised definitely all was not right.

Under warranty so booked in to Audi in a weeks time, I told them needs a new Haldex pump, I`ll keep you posted.

Update.
Went to change pump today after doing oil and filter last weekend.
Had everything stripped down and just the pump to remove but after taking the 2 x bolts out it was still stuck solid and could not get it to budge so had to put it all back together so I still don't have my pump changed grrr thank God I kept the old oil in bottle and saved using another new one.
Will have to book it in somewhere so can get it up on ramp.

That's a shame mate but fair play for trying. Probably a fair bit of friction to overcome by the two 'O' rings - do you have an oil filter chain wrench ? I'd be tempted to get that on it to get it turning and help work it loose.

Na sure if there be room to get chain round it and body of pump is bit flimsy going by feel, think it could be stuck solid with rge heat from exaust as that runs just past it also.
I'll get it booked in this week.

So, car booked into dealer tomorrow. When I booked it in last week, I told them that traction was cutting in too much and car felt front drive only and that I thought problem with Haldex pump.

So today received call from gentleman who sounded like service manager who wanted to know "what exactly was problem again?" And that he had never heard of any Haldex pump issue and am I sure it's not weather or tyres.

I can already see where this is going tomorrow and that car will seem fine , it's the greasy roads.

Has anyone got any facts/data/fault codes I can quote or be telling them to look at?

Cheers

I'd imagine they'll do a scan which should reveal a Haldex fault code if there's a problem.

From my experience of having Haldex issues there should be no wheel spin or T/C intervention when pulling away from standstill with 30% full throttle (maybe even 50% on a standard car) even on damp or greasy roads it should just hanker down and get on with it with no fuss. Also if rear end dips and front end rises that's a characteristic of a front wheel drive car.

Cheers, fingers crossed they will pick it up. I'm not expecting it to be stuck like glue with 300 horses charging but pulling away rolling start about 10mph and giving it 50% throttle surely TC shouldn't be kicking in?

So picked her back up yesterday, new Haldex pump/controller fitted... oh, my fecking god!! I got used to front wheel drive to an extent and forgot how much she grips even at full chat off a round about in the wet...... back to gripping like something to a blanket and even on wet greasy roads, not a flicker of TC.

Anyone seeing TC light up on dash I recommend paying the garage / dealer a visit.

Lol glad it's all sorted - feels like someone in the back with their feet in the back of your seat pushing you along now !!

Update then as I originally started the thread.

After being at my local dealer for 4 days I picked my car back up yesterday. I wasn't able to give it a proper abusive roadtest but it seems much better. I'll have to give it a damn good thrashing to check for sure.

I am advised that the issue was a faulty haldex coupling preventing it from working. Coupling has been replaced.

Fair play to Blackburn Audi though, car was out of warranty but they have investigated and done the work FOC. Not sure how much of that is a result of being told on a number of occasions by a number of their technicians that there was nothing wrong...

good to hear, well hopefully...... good that they sorted FOC......

Was you getting lots of TC interruption before?

Lots of traction control light and under various levels of acceleration lots of vibration from the front end when it was scrabbling for grip. Not a pleasant feeling.

I'm hoping to get chance to confirm it's sorted over the weekend.
 
exactly same as me mate........ honestly, after 1 mile of picking mine up after new Haldex control unit / pump fitted I knew it was sorted.... it transforms back to how it should be..... TBF I got used to FWD and forgot how much traction you get when all 4 wheels working properly....

If your not 100% sure straight away i`d say its not been sorted.
 
i asked blackburn audi to look at mine was honest a bout my mods they just laughed ha ha

Picked mine up the other week and did launch control about 10minutes later....yep! She's back on form again. I did get a nice tyre burnout vid before I they replaced it. They also let me pick a free gift! Got myself a nice suit case.
They gave me an R8 watch last time I had a Service. Lovin the Audi after sales treatment so far.

:-( just got new pump fitted but no joy still spinning front wheels.
Audi advised it was the pump but looks like they got it wrong so 250 quid out of pocket.
What else could be the problem, any help much appreciated.

Oh dear sorry to hear this, other issues could be Halex ECU, Haldex coupling (rear diff unit) or the transfer box - there may be more.
 
What a shitter !

If Audi advised you what part needed replacing to solve problem then surely you have some comeback on them?

I had the Haldex control unit changed on mine but think this maybe what the pump is called?
 
Yeah I'd not be paying for that pump if they advised it and it didn't fix it

The controller is the silver box that the cable from the pump plugs into and price for that is just under 900 quid from audi.
