I know the Freelander inside out but not had the pleasure of getting my hands dirty with the volvo AWD units(or ford kuga). I understand that there are various vibrations and noises that look likely to be caused by the Haldex unit itself. The majority of problems in Freelanders is actually a diff failure which i can now fix but in a way that will prevent it happening again (its a design fault). Id really like to to do the same for the affected Volvo cars. So if anyone would like to go into a detail about their own experiences id be extremely grateful, and if anyone is currently suffering issues and cannot get a resolution im happy to investigate the car free of charge (this is what i did with the freelanders to come up with a robust solution)
Im not sure if the guy i initially spoke to about his XC60 is on here, but he was stuck in a battle with Volvo to sort his car out, and was going to get back in touch with me but i havent heard from him, so if you read this give me a shout as im in a better situation to help at the moment (i have brand new Haldex 4 units in stock for a lot less than Volvo!)

Wonder if you or anybody can help. I have a 2004 D5 XC90 with AWD problems. I had the car plugged into VIDA and it came back with a code faulty communication code with the DEM. I've had the DEM repaired by lukas at volvodignostics and the rear diff has had a new pump, filter and transmission oil, but still no AWD. The DEM code was cleared.
I suspected that it might be the splined sleeve in the transfer box and I've tried turning the prop with all four wheels on the ground and the prop spins freely. Also I've had the car up on a lift with all four wheels off the ground, put the car in drive, the front wheels spin but the rear wheels do not, and the prop does not turn.
I've just come back from the garage now and they have said that after clearing the DEM code, they took the car for a drive and it threw the code again.
So I have a few questions to try and help me determine whether it is the splined sleeve or an electronic issue. (1) is the transfer from the angle gear a direct drive or it it clutched ? (2) if the DEM is working and splined sleeve is worn would this throw a DEM communication code when the AWD doesn't engage ? (3) are there any other electrical issues that would throw the DEM code ? I don't have any other fault codes other than a boost pressure issue, but that's not related.
If anybody can help I'd really appreciate it. I've already thrown around £1200 at this issue and I'm no further forward. Starting to get desperate now !!!
