Haldex failure thread

[brad65ford]

Damn this is surprising to see from Audi, sure hope the rs3 has a different unit since its making more power.

[nothome17]

This isn't reassuring to know Haldex has issues. Anyway for Audi to know without having to have to test drive? Can't they check the ECU history?

i would like to know this as well...

My 2016 S3 has been out the road since early spring. It's parked while I drive my Porsche during the warmer months. My problem occurred during a very light snow fall. As I was entering the highway I got stuck in a few inches of snow. My front wheels were spinning with no reaction from the rears. I eventually took the car into my dealer. When I did there was no snow on the ground. They were unable to reenact what I had reported and therefore could not find a problem. I was told to return when there was snow on the ground for a further review. The season ended with no further snow. Therefore I am going into this winter season with a faulty car. Can they check this Haldex without slippery conditions? Send me a private message if you can assist me. Thanks.

A faulty system will generate a code. You could also just engage Launch Control and light up the tires in their parking lot.

Ladies & men, my car is 100% stock as my car is under warranty. Hopefully when I place the car back on the road my local dealer will be able to repair the car. Thanks for all your kind replies.

Hey guys,
So 2 weeks ago i went eurodyne stage 1.5 ecu / DSG tune, took my car out for a test drive and launched it a few times only to find myself peeling the tires like crazy through 4 gears. yes 4 gears.
went stage 2 this week with a CTS down pipe and took the car to the track, and same thing, couldn't get traction to save my life.
at this point I'm assuming the is a Haldex issue.

the car has 70,000 km on it.
Stage 2 tune / deg software.
2015 model.
no error codes displayed on dash however i haven't looking with my software or any other method of scanning.

have to call the dealership monday, but not sure how to go about explaining this to them.
what have you guys said in the past to get them to warranty the problem when you have no error codes?

Thanks.

[mrubys3]

man reading through these threads this seems like it should be a recall at this point

[djlittle21]

Has anyone noticed a humming noise from the rear before their failure during lift off deceleration (no brake) around 45-50mph? I haven't checked for stored codes yet, but something isn't right...

[nesbit]

Anyone with an RS3 happen to note what revision is on the RS3s?

[A20V200]

So the car was "acting weird" so I decided to use my OBD11 and this popped up!! What are people doing when they go back to the dealership after being TCU tuned? Flash ECU and TCU back to stock and put the stock air box back on and hope for the best or what?

No dash lights or traction control lights...just a little squirmy going around some round a bouts and accelerating out of them.

And if the dealer tries to "stick it to me"...you know, because your car isn't stock and is modified and has X and Y....? Anybody have a cost of repairs?

Car has 21,000 miles on it now....this issue happened in the last week.

Update: After going back to my tuner shop, flashed back to stock ECU and TCU, I then went to the dealer and they could not replicate the faults since it was wiped clean after the flash.

Flashed back to stage 2 and stage 3 TCU and the faults occured almost immediately. I drove it for about 2 months and getting on it every so often to get the clutch pump or entire Haldex to fail completely and not just intermittently....Then the Haldex TSB came out and I contacted the dealer to see about getting my car in to get fixed. They still need the error codes to replace or repair. I think to myself, no worries, flash back to stock and launch control it to throw codes...

The funny thing is, I drove "normally" for about 2 weeks prior to calling the dealer, now the Haldex is operating just fine...I hooked up my OBDeleven and no codes at all...! WTF....self healing Haldex? Was there some debris in the pump? Puzzled...I can launch it and get on it and it hooks up just fine. No slipping or loss of power..NOTHING!!

WEIRD

It has been confirmed that it has a larger rear pumpkin, but no confirmation as to whether or not the Haldex unit, or even simply the pump is the same or not.

[onequick4door]

What fluid are folks using for a Haldex fluid change?

[SirScott]

Then the Haldex TSB came out

What TSB # is this? I'm having the same problem and would like to go in as prepared as possible. 2016 S3, 29k miles, FWIW.

[Seinsmeld13]

My S3 has been off the road since mid March while I drive my summer car. My fault has not been repaired by Audi as they were unable to reenact the poor traction I reported in the snow. Is there an automatic Haldex repair?

[A20V200]

There is a TSB out for faulty clutch pumps and or the entire Haldex unit. Call your service advisor and report your issue and tell him your aware of the TSB and they will test it out.

[949]

is the tsb for all 8v s3's?
i have a 2015 s3 and was not told about any tsb. is it where it would only come up if there was proven issues like a cel?

[bmc333]

1. In the rain, FWD slipping
2. 26K
3. 2015
4. Any error codes - nothing specific to the haldex
5. Awaiting appointment/diagnosis from NGP

[Klim89]

They replaced the pump, changed the fluid, drain plug and had a "replacement kit" which they said was to for the pump and motor replacement. I will try to get the invoice and part numbers when I get a chance

Do you have a copy of the invoice?

AFAIK..the TSB is on the "downlow" at the dealership....they are not telling/sending out any info on it, unless yours is faulty and you ask them about it and have the appropriate codes for them repair the pump or haldex. I had my car flashed back to "stock" wiping the codes out, but they did the output tests on it and it passed and threw no fault codes. I showed them my OBDII screen shot, but that wasn't enough to prompt them to fix anything because the ECU did not have a stored fault code and they "could not recreate it during their testing".

[CJ_S4]

I'm having this issue too it looks like. Bone stock but a spirited driver.

This morning pulling into traffic under full throttle I smoked the front right for about 100 feet.

[Edit] Confirmed this weekend with launch control. Car barely moved as one wheel spun furiously. It was pretty hilarious.

[CJ_S4]

UPDATE

Car is in the shop currently getting the rear differential replaced. I was able to replicate the problem for the dealership, they scanned and found 2 faults related to the AWD system.

1. How you discovered you had the issue - Consistent wheelspin from front wheels only. Bad torque steer
2. Mileage - 19,XXX miles
3. Model year - 2016
4. Any error codes - None apparent on the dash, 2 faults found when scanned
5. What was done to fix it, and was it under warranty? - Fixing under warranty by replacing rear differential (contains haldex clutch pack that engages rear axle). EDIT: 1/5/18 My car was in the shop for 2 months waiting for the correct diff.

[Seinsmeld13]

My car has been to two different Audi dealers with the most recent being November 11th. I have been told by both dealers that there is no recall for my car for any issue which of course includes the Haldex. I have been told to return my car when there is snow on the ground to see if they can reenact my reported issue with the AWD. Can anybody help me with this traction issue or give me a recommendation? Thanks in advance.

Did you NOT take my advice from Vortex?!?!?!

get yourself a gopro or some camera with a slo mo app and get out there!!!!!

[SirScott]

tl;dr: By replacing the haldex pump, 0CQ-598-549, my car is now fixed. TSB# is 2043144/3

Here's what it looked like when broken: https://www.youtube.com/watch?v=D4IEBYcOecE

The invoice for the repair.

*Edit: 29k miles on the car when fixed. Probably 27k was when it started to break. The traction became gradually worse, it's not like it suddenly stopped working overnight.

[Iliketurtles]

Long time lurker first time posting

Recently had this fixed.


1. How you discovered you had the issue - Wheelspin on hard pulls even in second and third gear.
2. Mileage - 26,XXX miles
3. Model year - 2015
4. Any error codes - None on dash. Dealer paperwork showed tech found stored fault code
5. What was done to fix it, and was it under warranty? - AWD and Final Drive W. Clutch removed and replaced under warranty.

Notes show that when tech lifted vehicle and spun wheel the AWD system was engaging and all of the wheels would spin. Then they checked the fluid condition and found the oil had clutch material in it and proceeded to replace clutch unit. I waited a bit to launch to get the new clutch a little time to break in and everything is back to normal now.

[TWS3]

Just came across this thread. I have a 2016 S3 and so far no problems, i have done multiple launches(15 or so launch control) but I only have 8500 miles. I looked at my Haldex and it has a “G” stamp so not the F or K. Has anyone had any issue with this version?

[kjeeper10]

Hmm looking at a 2015, how common is this ?


2007 Audi A6 3.2 daily, 2007 Jeep Wrangler Rubicon 3.5” lift 37’s moderately modified.

1. How you discovered you had the issue?

I launched the car and took a slow-mo video and it’s so obvious.

2. Mileage

4. Any error codes
No, nothing at all.

5. What was done to fix it, and was it under warranty?
Took it to the dealer and they are blaming the tires! Waiting for a more technical explanation this week.

Were you able to look at what letter your rear diff has stamped on it?

[maskari_gti]

I couldn’t check that as I don’t have a lift or a jack to do so. I’m not that slim to fit under either.

It was so obvious in the video that the rear wheels are been dragged by momentum nothing more. Yet the technician kept saying that it might be the tires. I didn’t want to argue much as there’s no point in doing so. So I booked an appointment for Tuesday to get a thorough look into the Haldex.

1. Exceedingly poor traction in snow and other slippery conditions. Also, took some videos to see if there was any power going to the rear.
2. 35k miles
3. 2015
4. No codes pertaining to powertrain or the Haldex system specifically.
5. Awaiting appointment for local Audi Dealer. EDIT 1: Dealer is ordering in a new clutch pump. See later post for link to Repair Order.

I am experiencing the same thing. As a new Audi owner of about 8 months, I've loved the car. I never really launched it but the acceleration was always there. In the snow, things have been very lackluster. I was expecting better performance than my Isuzu Rodeo beater but the Rodeo handles the snow better.

Now after reading all of this and re-watching the videos I've taken, I think that the Haldex system just out right isn't working. I will post two links. The first is a snowy acceleration with TCS on and the second, TCS off.

Do you guys think this is proof enough for a dealership?

Thanks in advance and I'm diggin' the four ring circus thus far. (Sans haldex....)

I agree, looks like haldex is not working at all. i would definitely have the dealer look into that. have you looked to see what version of haldex your car has? what letter is stamped on the unit?

[GreyA3]

Thanks for the reply.

We have an appointment for Friday.

I haven't gotten under it as it's winter and no garage :(

I'll keep this updated though

I have no problems with my 2016 @ 8k but...

Could the repair be as simple as replacing this part? https://www.ecstuning.com/b-genuine-...kit/0cq598549/

That would be far cheaper than I was fearing. I was convinced not to mod after reading about these problems.

If the repair is under $300, that's more in line with a VTEC solenoid on my old Integra, or Timing chain tensioner on my old S2k.

That looks like a reasonable fix if you're out of warrenty...good find!

[GreyA3]

This maybe a silly question but I'll shoot.

Does Audi charge any inspection fees for warranty covered vehicles?

I wouldn't think so but I'd like to not get blindsided with 100+ bill atm.

[maskari_gti]

So after showing the dealers the video and trying to convince them that the rear tires are being dragged and no power at all, they still believe that his behavior is normal!! They asked me to drive for few days and come back to them.

They changed the haldex oil and were happy to give me the car back!

I'm going back again on Sunday and this time to get some something more convincing.

[VWVW]

This is very common.

I started noticing slipping and wheel hopping at around 20000 km. Had the haldex pump replaced (took the dealer 1 min to scan and they found the fault) and it has been going strong ever since (now at over 55000 km). No more slipping or hopping.
