DEM 0006 error on VIDA. Xc70 2006 D5
 

Got a xc70 2006 with 200k.
Checked the prop wasn't spinning before I bought it.
Scanned with VIDA and it comes up with the following error code.

DEM 0006 Pump code faulty.

Question is what's caused it?
Could it be just oil contamination, blocked filter or a dead pump..... Or something worse such as DEM issues.

Looking at the frozen details below it occurred around 190k. Cars now on 201k.
I will get under the car once its been collected as I want to service it before using it.

With mine it was the brushes in the pump motor that went.
I had to replace the pressure sensor too.
Mines an '06 with about 275,000kms on it when the pump went.
I replaced the filter and oil while it was open too.

Hi how did you know the pressure sensor needed changing?

Where did you get the pump bushes? Any guide on how to change them?

test the pump , unplug it from the DEM and apply 12 volts if it sounds to rotate it is probably the DEM at fault ...

I changed the brushes with a set from an old cordless drill initially to get the pump running, then the pressure sensor was throwing fault codes on it's own.
I eventually replaced with a new pump, new oil and filter and a new pressure sensor. It has been running fine for 4 years now.
The pump should be running all the time. check for 12v on the pump. there are fuses in the REM that feed power to the pump.
