F5FF BSI corrupted ?

[Pedro]

BSI fault F5FF keeps rearing its head I have a door module issue with what looks like may be wiring to the passenger door mirror a mate in dealers reckons its the flexi wires in the door as they appear to be getting 207 -308s with this fault on a regular basis he also asked was the car showing unusual outside temps?

Assume you’ve tried a BSI reset?

Yea 3 other codes came up after its knocked the air con off as temp issues coolant level & engine temp normal shows as engine wring harness faults- ECU shows oil pressure fault fluctuating between high/low pressure although oil was changed 2250 klms earlier & the car has no running problems except slight hesitation pulling away which I think maybe plugs as once their cleaned it disappears need to go digging ?

Try pulling fuses to isolate sections of wiring & see if the codes go ?

I have managed to get rid of the the F5FF with scan tool now BSI has no faults showing however the ECU has logged coolant fault & door module fault is still active
F40A is as before original with scan oil level full oil pressure no faults could be a Ghost from way back I did suspect fuses which will need checking but scanned again today & engine wiring harness is now showing no faults so at the moment I'm on my son's Focus ST oil leak so the Z is now on the to do list
