Hi there we have a 2014 new shape 2.2 rwd transit
We brought it with front end damage
It's all back together but we have electrical issues
Whilst driving the heated front screen randomly get hot and blurry but the switch is turned off after 30 seconds the warning beeper goes off and dash says service engine then after 30 seconds the warning goes off so does the heated windscreen
Also one day engine is quiet the next it's rattley as if the timing is out
Can't find any wiring damaged or find anyone who has had the same problem and ford won't look under warrentl as it's been crash repaired
Any help would be appreciated
