Hi. My name is Eirik and I live in Norway. I have a 2005 A3 3.2 VR6 DSG.

I have a big problem with the Haldex system. It spins on the front wheels when accelerating. But sometimes it seams like its actual working. But most of the times it don’t.

I performed a diagnose with VAG-com yesterday and got the following error codes:

Diagnose 1:

VCID: EAD08990C564499

3 Faults Found:

014 - Defective - Intermittent

1 Fault Found:

013 - Check DTC Memory - Intermittent


The errors was deleted, then I did a test-drive. Still spinning on the front wheels. Defiantly no haldex :-\
Performed a new diagnose an got only this error:

Address 22: AWD Labels: 1K0-907-554.lbl
Part No: 1K0 907 554
Component: HALDEX 4Motion 0101
Coding: 0000001
Shop #: WSC 00000 000 00000
VCID: EAD08990C564499

1 Fault Found:
00448 - Haldex Clutch Pump (V181)
014 - Defective - Intermittent


Can someone please help me sort this problem out. Is it the Haldex controller or the pump??

Regards,
Eirik​

Thanks for reply

Yes looks like that from the error codes. But I have found links to other threads saying that a faulty controller could cause error on the pump.

We ran a test on the pump from the diagnose software. I did not hear any sound under the car though.

maybe try and replace parts 1 by 1 cheapest first!?
 
Thanks I will properly just buy a new complete diff. But first I have to check all the wireing. I know that they could get corroted.
 
Your haldex priming pump is dead, happened on our R32 (uses the same diff), you need to replace it, you will also need refill with haldex oil as it comes out when you fit a new pump. It can be done easily (i did mine on the driveway with axle stands), just 4 allen key bolts hold it on.

Sounds good :) Hopefully it will only be the this pump. What do you think about the other fault codes?
Do you know where I can buy a new pump and what they cost?

Also the strange this is that sometimes the haldex kicks in and works for a short time. Did the R32 act like that when the pump was dead?

Regards,
Eirik

Looks like a repair set for the pump is avalible that includes a new pump, around £165

New Haldex is about £1175 :faint:
 
I just got my hands on a complete Haldex diff from a 2007 Golf MKV R32 with 20.000km on it for just 250£

So think I would go for that :)
