I have a 2010 ford fog, So few months ago my partner degreased & gernied under the bonnet of the car whilst the car was running all was well
Turned it off & went to turn it back on few hours later & just won’t start now.
It has a SYSTEM COMMS FAILURE fault come up on the screen the reds, stereo everything else stil works sweet it just won’t start?
We’ve had all the plugs pulled out & put contact cleaner ect on them & same issue??
