Hi Ian
Many thanks for your help sorry for the late reply been stuck in isolation. It’s interesting because the problem seems to have started since I removed the solenoids and cleaned them. The codes I’m getting are
F5FF unexpected re-initialisation fault from bsi
P0366 fault in exhaust cylinder ref sensor signal consistency
U1108 fault no communication with engine ECU no signal or fault engine status information
U1318 operating fault caused by BSI
U1003 communication fault on can
Thanks

Have you tried clearing these codes? Some may be historical. The odd thing is you are getting a P code from the engine ECU but there is another code suggesting the engine ECU is not communicating. This could just mean the P code occurred before the communication problem.

U1108 is the most serious because it suggests the there is a fault on the CAN bus that links the engine ECU, ABS and BSI. I suggest you:
(i) Disconnect the battery (follow the 3 minute rule see last paragraph).
(ii) Check All engine fuse box fuses especially F10
(iii) Unplug and inspect all three engine ECU connectors for water ingress or other signs of damage
(iv) Inspect the the plug on the ABS (the CAN bus from the BSI loops through the ABS before it connects to the engine ECU)
If you have a multimeter it would be worth measuring the resistance between pins 6 and 14 of the OBD connector. It should be 60 Ohms. If it's 120 Ohms it will confirm that the engine ECU is not connected.

P0365 relates to either the front solenoid or the front camshaft sensor but we need to sort out the CAN bus first.

The first fault F5FF suggests the battery was disconnected while the BSI was awake. This can corrupt the BSI. It is important to open the bonnet, turn everything off, take the keys out, shut the doors but leave drivers window open for access and then wait 3 minutes before disconnecting the battery.
