I see in this thread it was the Fuel Relay.
I will check the contacts to the Relay in case they are corroded.

Fairly sure its not the Crankcase Position Sensor as I had that at the start of the year and there is a genuine Volvo one it it and I've barely driven much miles given the pandemic. Also when this failed before there was no 1-4-4 error.

Fault seems to happen when the car is fully warmed up (after 40-60mins of driving) so thinking its some electrical connection getting hot and loosing contact. I've tug tested the CPS and Temperature sensor wires when it running and also wiggled the Fuel pump relay but to no effect.

BTW what's an LH Module?
