Hi everyone,
I really could do with a bit of help as my focus has been acting up.
Esp light comes on, turn engine back off wait 5 mins and it usually disappears. When driving it's in limp.
Occasionally eml comes on too but not every time, maf sensor was replaced a few weeks back, a genuine ford part.
Taken the car to a garage this afternoon and had it scanned. Fault code was u2023
Communication error.
Has anyone had this sort of problem before, I need help!!

 

Find a competent mechanic, because without a proper diagnosis you're going to be firing a very expensive parts cannon as so many people do.



If it is genuinely a communication issue ( again, better diagnostics would give more info than a basic code which means little, they need to diagnose each module within the vehicle to see where any comms issue may be, or if any specific modules have issues ), it could be a wiring issue ( damage, water etc etc ), faulty module within the vehicle, or more.

So if you do not have the equipment to perform tests, the knowledge how to....you're fighting a losing battle here. But make sure any garage working at it are competent and with the right equipment, otherwise you're paying someone to waste your time and money.

A little googling even here brings up stuff

Thanks for your reply, its going to another garage next week and they do specialise in electrics so will be able to look deeper and diagnose better
