FORD MONDEO TITANIUM 2.0TDCI 2008

I admit, i have posted about this in two or three forums groups but as yet have had no luck.

3rd time lucky??

As briefly as i can, i will list probs

Convers+ stuck on Trip Computer & Settings 99% of the time, i say 99% because occasionally when i press to power on the Sony entertainment system i do, but very briefly and never lasting for more than about 30 seconds get the menu for this!

Sony entertainment system does NOT hold memory for clock/date and NEVER recognises if the ignition is on or engine is running as always flashes the 1 hour signal. It also intermittently turns off and on of it's own accord!!

Intermittent airbag warning light comes on. This don't always illuminate but the only way to get it off is turn ignition off and completely remove key.

As far as i am aware there are no other electrical issues with the vehicle.

I have had it plugged into a on board diagnostics device and although few error codes appeared, none were related to any of the above and none could be cleared, or them that were cleared immediately came back!

HOWEVER

They were ALL said LOSS OF COMMUNICATION WITH BODY CONTROL MODULE

Someone must have experienced something similar? Vehicle has already had a factory spec battery replacement 4 days ago.
