Hello,
my AWD on my V70R 2005 gave up last week and I'm hoping anyone of you can help to find the reason and/solution.
A few words about the car:
- I have no error message in BCM or fault code of DEM in VADIS.
- DEM was replaced 2015 (new by Volvo dealer) after sealing gave up and PCB was damaged.
- Cleaned the fuse of DEM in REM. Fuse is okay. BCM reacts on removal of fuse with DSTC error message.
- Sleeve was replaced (and well greased) 2019 when gearbox was changed. Shafts/gearing looks good on M66 and angle gearbox.
- no noise from below, no impact or sth. which could mean a mechanical fault
- Haldex oil + filter was changed two years ago, el. pump changed 6 years ago
I got the following data from VADIS while driving:
-4 identical wheel rotation signals (increasing with actual driving speed)
-around 14.xx voltage
-around 0.29xx pressure (no unit shown by VADIS)
-Solenoid between 13xx-14xx (no unit shown by VADIS)
-Oil temp starting at 0 and increased up to 20 while driving after cold start (no unit shown by VADIS)
-there was some pump current shown but I don't remember the value
I've read that a faulty pressure/temp sensor or solenoid of the DEM can result in disfunction of the AWD w/o showing any fault code.
Do the above mentioned signals point to an faulty sensor or solenoid?
Any other ideas what could be broken w/o giving a fault code?
Many thanks!
