Over the last few days I've noticed whenever I put my foot down my wheels are spinning and the traction control light is flashing. Seems like the power is going all through the front wheels.
Been doing a few searches to what's causing it, it's looking like either the haldex oil is very low so it's cut out to prevent damage to the system or the haldex pump has gone. I'm hoping it just needs a service so think I'm opting for this option first (fingers crossed)

Anyone had any experience with this?
 
More than likely the pump, pretty common . Fault - V181

I've had it on the diagnostics and it said 'haldex pump intermittent' I'm just thinking do the oil first to see if that fixes it as I've heard that sometimes works. Can always do the pump afterwards if it needs doing.
How much is the pump roughly?

There's a mesh filter inside the pump, just read an interesting post on Briskoda where cleaning the filter cured the problem. Sludge builds up on the filter causing the intermittent flow of Haldex oil.

Got a link?
 
Booked into Audi for a haldex service on Monday £99! Fingers & toes crossed it works
 
Good look with just hoping to get away with the oil change.

Just had mine fixed. I used Carista and VCDS to confirm error which I have attached to this post. Using VCDS i tried to manually activate the pump using the test feature but it would fail. I was also getting a battery quintessente error but thought it was something else.

New pre charge pump for gen 4 is hard to get hold of. I got one for £206 from an audi dealer online ( don't be fooled in getting a Chinese copy to save a few quid ). Not sure what Gen your car is running though.

I will post a photo of the old pump after this post. New pump takes 5 minutes to change and you will need to put new oil in again.

My old pump. Im going to try and clean it and give it a test. I think the brushes inside have collapsed and falling out as the old oil was full of small metal filings and car has low miles.

By the way Audi shouldn't be charging more than £89 for the haldex oil change, its a fixed national price. Cancel, and book again online.

If you need a contact to get the pump for £206 rather than £260 and and oil I can pass you the details.
I needed 4th Gen oil which is about £60 but got it for £30 ;) All Audi items.

I was just about to look for the link, but this covers it.
There's been fairly good results from cleaning that sludge out of the filter but, you may find this isn't done during your Haldex service.
well worth doing and certainly seems to cure the intermittent fault.

I've mentioned the filter change to them which they said 'doesn't need doing' I'll be reminding them on again on Monday that I want it replaced while doing the oil. Cars on a 58 plate just hope they stock the filter.
I'll get them to take a look at the pump as well see if they can see anything.
Car was driving fine last night, 50mph foot down in the dry and no spinning or traction light.
 
Yo! Got the car back, noticed on the drive home through 1st/2nd/3rd wheels still seemed to be spinning and traction light was flashing. Tried to launch the car in 1st (normally don't get any wheel spin and it just goes) this time it barely moved lol.
Before I go ahead and try sort a pump out, there's no way this could be related to my sh*t tyres or the fact my car is pretty low on coilovers? Or anything else for that matter.

You need to get it scanned with VCDS to see if it's logged any faults on the Haldex. There's a VCDS map at the top of the forum, someone local will help you.

Had it scanned already, come back with haldex clutch pump intermittent.
 
OK, so that is your issue then, not your tyres. Probably just needs an oil and filter change as it may be overheating, hence causing the intermittent issue.

Dealers won't change the filter on Gen 4 as it's not a service item according to them - they won't have a part number for it.
 
Had it back down to Audi today, took a mechanic out for a drive. They want to get it on the diagnostics to find out what's causing the problem. I've already told them I've had it on my friends which showed the clutch pump intermittent fault but they want to do the diagnostics anyway.
 
I've got the same problem with my a3, been told it would likely be a new pump. It seems like it only engages half the time which seems weird

So that's 3 Haldex issues? I wouldn't be surprised if it's down to lack of filter replacement and Audi will insist on changing the entire pump (which will obviously fix the issue as it comes with a new filter).

p.s. sorry for being so skeptical of Audi, not all main dealers are bad!

Apparently on my haldex the filter doesn't get changed just the oil, those are Audi's words.
Maybe a dirty old filter is the reason behind the intermittent fault :fearscream:
 
Just bite the bullet, it is going to be the pump without a doubt. If it was the haldex control unit you would get a "01324 Control Module for all wheel drive (j492)" fault. Error you stated is the pump and I bet without a doubt you can't activate the pump with VCDS which will confirm the error.

Mine is a Gen 4. I had the oil and Haldex & diff oil changed while my AWD system was working fine just after a full service. 1 week later front wheels started spinning with traction light coming on etc. I checked Control unit which was fine. Replaced with a new Audi Geniune pre charge pump and bingo, worked immediately.

Not many in stock for the Gen 4 though. I live up near Newcastle and ordered one from an Audi dealer all the way down the country who had 1 left in stock and 5 on back order from Hungry that had been pre ordered for over 2 weeks!! They might have them in stock now. I can give you contact details as they discounted from £260 ish to about £206 ;)
 
Got car back after srvice and the following is the outcome.
Ran GFF no faults stored.
Road tested and confirmed fault no 4 wheel drive, carried out test plan for haldex pump and have advised I need new pump and oil change.

So all in all it is the pump, now do I change filter before changing pump or just bite bullet and get the pump ( anyone know best place to get ftom)?

Also have a prop shaft donut seized and have been advised I need new prop shaft +bolts and donut (anyone know where best to get this also)
2007 s3

You can buy the doughnut for front or rear as an aftermarket part. Audi will tell you that you have to buy a full propshaft as it's one unit and costs nearly £900. I know as mine was done under warranty after buying the car 2nd hand from arnold clarke. they coughed up and replaced it but I found out the rubber doughnut can be bought for about £180. think I had a link somewhere I will have a look.
 
Thanks for info, it is the back one I will need.
Have the following quote from audi but bit confused with it so here it is word for word.

Prop shaft donut seized advise new prop shaft and bolts or if donut comes separate please price donut £462.97
1 hour to fit

Am I rite on thinking I am getting shaft and donut for 462.97?

Rear one. send them your details to make sure it will fit but looks right 1. much cheaper and if ur handy with diy easy enough to do yourself or get a local independent garage to fit. literally remove bolts,pI'll propshaft out enough to remove and replace with new.
 
Cool thanks and yes I'll be fitting myself along with new charge pump but ill try oil and filter first.
 
Had another diagnostics done today by a friend with the vcds. 100% New clutch pump needed.

Did you get this sorted mate?
Done the oil and filter yesterday ut no joy so ill be off to audi in the morning to see if I can haggle a discount on the pump.
I'll let you know how I get on
 
Hi Guys,

Im interested in this thread as ive suspected my haldex isn't working. Front wheels spin and traction control cuts in more than I would have thought but as this is my first haldex car im not sure whats normal. I see you talk about pump failures and filter cleans but I don't know how old or mileages your cars are.

Ive got a 12 plate S3 with 23k miles. Which gen of haldex do I have and is it likely to be faulty ?

Thanks
 
You have a gen 4 Haldex which are pretty reliable. You sure it isn't just a combination of low temp and low tread on your tyres? If you're still in doubt, get a local member to scan your car for faults.

Get the car scanned. If it comes up with clutch pump intermittent then it's probably goosed. I could never get any of my wheels to spin till my pump went now it's pointless putting my foot down.

Tyres are fine with 6mm P zeros. To scan do u mean plug in diagnostics OBD and look for errors ?
 
Carista app on phone will pick up the errors as I used Carista first due to always having a blue tooth obd dongle connected but then used vcds to check properly and run an output test on the pump.

Will be pump if you get same error shown in my.screen shot above. very common after 40k miles on same pump in Gen 4. so common it's hard getting a replacement pump in stock. I can give you link to an audi dealer that might have stock and knocks about £40 off list price Inc delivery.
 
I think the reason why they are failing is that Audi don't tell you to change the filter at 40k.
 
Yo... cars been in this morning for a new haldex pump and oil change. Problem solved! No wheel spinning at all even driving back on the wet roads, it's like driving a new car :smile new:
