S80 AWD issue mechanical faillure
Good evening All,
I have a VIDA message saying mechanical faillure of the oil pump. No pressure actuator sliping (something like that) 2000 miles ago the AWD of the car was working fine on gravel. No idea if the message was already there. I changed the filter and the oil but still the same DTC message and no AWD. When the car in P position I can't move the prop shaft or rear wheel shaft. What can be the problem ? faulty pump ? faulty sensor ? Thanks for the help. |

What is the actual DTC code?
You can check whether or not the haldex oil pump is working by removing electrical connector and connecting a 9v radio battery across the terminals. You should be able to hear the pump. You can also get live data via VIDA/DICE of some haldex/dem conponents. As you cant rotate propshaft it would suggest issue is in the Haldex unit/components or the DEM. Cheers Bob |

Thanks for the reply. I was abroad. I will have a look tomorrow.
By 9v battery you mean something like this ? DV019_Jpg_Regular_424922_single_above_R.jpg Thanks |

What’s your mileage. My xc70 had a knackered pump at 200k
Haldex filter had never need changed since 06.

I have 71000 miles. I noticed the AWD stop working arround 70000 miles so I decided to change oil and filter. The oil was black but not too bad. Changing oil and filter didn't solve the problem.
I will try to have a go with the 9V battery |
