Hi, I have a UK 2004 XC90 and which makes a groaning noise when turning hard right (loudest when accelerating at full lock from standing start).
I took it to Volvo dealer today and their technician stated as follows:
FAULT CODE DEM0006 PUMP FAULTY 4WHEEL DRIVE N/W POSSIBLY REQ DEM UNIT/CAUSE OF GROANING NOISE
Unfortunately their quoted price to repair this was £2,964.60 - way outside my price range !
Two questions:
1. Do you think this DEM0006 error could also be the cause of the groaning noise at full lock?
2. Is there any way to know whether the DEM0006 error would be resolved by replacement:
*Haldex 2nd generation pump (

*Differential Electronic Module (eg

Many thanks
