please can you confirm relay and location. Had already checked fuse 53 next to relay8 also fuse number48 is ok. Is there a exhaust Gas temperature sensor that is only other fault code that came up once.
Checked fuse 54 and checked fuses 48 and 53 again, all are ok. Assume you were referring to engine bay fuse box on drivers side bulk head.
Sorry for delay, had to wait for it to stop raining before jacking up again. All wiring seems to be connected.
The lambda/ oxygen sensors do not heat up, when I turned on ignition and checked as you suggested.
