I have the error message
Warning: Power Relay Failure
Engine does not starts or stop.
Acknowledge fault by pressing OK button
Check fuses and relays at engine.
The engine will start and run normally, so I’m assuming this is false alarm.
Does anyone know how to clear the fault ?
I’ve powered down but the fault will not clear.

The computer is seeing low voltage coming from the MPR. Either there is a bad connection or relay is failing. The motor has 4 relays I"I think".

The MPR is the one on the left facing the motor
Left to right relays
MPR, Fuel pump, Stop, start

Swap the MPR with one of the others

Many thanks for the info.
The details you provided were the money !
A huge relief for me.
I wiggled the relays, turned the ignition off and back on, problem solved.
Please keep up your good work in assisting tbe DIY community..... I would have paid £160 hour for the local Volvo dealer !
Top man !!!
