Might also need to change the 4/2 thermostat as the coolant didn't get above 60 degrees and the oil temp ditto.

Ok
So I have now sorted the problem.
After putting in a new OEM pressure sensor, the red flashing light stayed on.
I traced the wire back to the ECU and found bare wire where it was rubbing at a bend.
Replaced the wire and light went off at last.
Was getting under/over boosf in the turbocharger, P0299 and P2563 codes...eventually cleaned boost pressure sensor on the intercooler outlet pipe with brake cleaner and all the codes have disappeared.
I did use a vacuum pump to check all the pipes and the N75, etc which showed everything was working.
I had taken the air intercooler pipes on and off so many times, like a brides nighty, to sort the oil cooler so must have affected the sensor as the faults had come on after all the messing around.
Now must change the 4/2 thermostat...maybe over Easter.
Happy now.
Thanks for your help C
