I would be very glad if you could help me with the following issue with my 2005 Volvo S60
The car showed me the "Anti-Skid service requied" message. First just after driving 20-30 mins, later was the message from the first second there, and didn't went away since.
I was already at two official Volvo dealership to solve the problem, but they just seem to be not very competent or helpful. First dealer said that there is maybe a problem with the DEM or with the AOC pump, they wanted to swap it, but they couldn't say for 100 % that the problem is with this components. As they are very expensive and the dealership couldn't convince me, that the problem is really the DEM/AOC pump (in the first place they said that there is propably the SAS what went wrong...), I took the car to another Volvo service.
They have provided my at least the list of the fault codes (whey couldn't help me further, which I think from an official Volvo dealer/service is really sad...), the codes related to the AWD, Anti-Skid systems:
BCM-0094: Communication between control units, Communication problems with DEM
CEM-1A64: Communication with AOC control module Signal missing
DEM-000B: Oilpressure Faulty value
Another Haldex "expert" has after a 5 hour long struggle said, that there is a CAN-Bus communication failure and he cannot determine, whats wrong with the AWD.
Could the DEM-000B, the bad/misreading oil- and temperature sensor lead to all this problems? If the sensor sends faulty values to the DEM, the DEM will not respond to the ECM and the BCM, am I right? Therfore the ECM and the BCM will give a fault code, stating, that the DEM is not communication. Could my misery be solved with just the changing of the oil pressure sensor in the Haldex unit (and the changing the AOC pump will be also good...). The car has run 120k km's, and I think the previous owner didn't paid that much attention to the Haldex/rear differential. I have changed oil and filter in the Haldex already.
When the oil pressure sensor is changed, i still have to go to the dealer and ask them to delete all the fault codes?
Thank you, ***** ***** can provide me a correct answer!
