Hi All
Thought i'd share an experience i've just had with you all regarding Haldex 4wd.
I have a 2005 A3 Quattro s-line and the other day i had the abs warning light come on, this went off after recycling the ignition and stayed off for the remainder of the day, the following day, this happened again but did not go away!
and on my school run, it felt different and then spun it's front wheels in the wet!!, OH DEAR!!!, no 4wd.
A subsequent scan showed
Address 22: AWD Labels: 1K0-907-554.lbl
Part No: 1K0 907 554 A
Component: HALDEX 4Motion 0105
Coding: 0000001
Shop #: WSC 00000 000 00000
VCID: 2B5162E4F383
5 Faults Found:
00003 - Control Module
014 - Defective - Intermittent
02248 - Valve for Controlling Clutch Operating Angle (N373)
014 - Defective - Intermittent
00448 - Haldex Clutch Pump (V181)
014 - Defective - Intermittent
00003 - Control Module
014 - Defective
02248 - Valve for Controlling Clutch Operating Angle (N373)
014 - Defective
And also there was an advisory fail on the ABS saying check DTC's
Having done a lot of ringing about and speaking to both Audi and VW techies and also Awesome Gti store and a few others i found out that.
1. All gen2 controllers are interchangeable, ie petrol gen2 varients and diesel gen2 varients can be swapped beteen cars as these are all the same. one point to note though, always try to find a unit the same age or newer as some software is not backwards compatable!, ie newer software will work on older cars but not the other way around.
2. Complete Haldex rear diff set ups can be swapped between VW and Audi Diesels, ie A3 Quattro and mk5 Golf 4motion, but not between fuels, ie diesel will fit diesel as the haldex final drive matches the gearbox final drives.
3. Gen 4 units look identical to the gen2 albeit with the deletion of the filter plug/cap but these will not fit.
After trying to clear the faults down with no luck i found a good low mileage controller off ebay, it came complete with the 2 valves that the controller sits onto, this controller came of a 57 plate R32, it fitted perfectly and as soon as the ignition was turned on, the fault had gone, meaning no unnecessary coding!
Guide prices for rear diffs are about £200-£300, some companys quoted £700 so please shop about if you're going to change the whole unit.
Hope this helps anyone in a similar position
