General: DEM Repairs

[gasc2188]

Hi,
My Volvo XC90 suffered problems a few weeks ago in that it began to display the message "Brake Fault stop safely". This changed to "Anti Skid Service Required". I could clear this with turning the ignition off and then on again. Initially I thought it was the BCM, but after testing loads of things and getting nowhere, I was forced to admit defeat and take my car to Volvo for testing. Dont know why I didnt do that first, but I'm now aware the DEM is faulty and is off the network when it was plugged into the Volvo diagnotic system. The wiring has been checked and everything is fine up until the point it gets to the DEM. My problem is the price of a new unit; £1480. Does anybody know anywhere these untis can get repaired. I cant personally understand why they are so expensive, do they have platinum internal parts, or diamonds maybe that I can remove and sell on to fund the price of a new unit. Sorry for my sarcasm Mr Volvo, but it does seem a tad expensive for a metal box no bigger than a packet of cigarettes.
