Hi there good morning to you and sorry for the delayed response

Ok the first thing to check and most common cause is s loose multiplug at the fuse box

There is a fuse box /gem module located in the passengers footwell under the glove box

Can you have a look at the two thin multiplug on The bottom of the fuse box to ensure they are clipped right home as I have had issues over the years where by one of these plugs is just not fully home and was causing similar electrical issues with the vehicle this can be caused if the plug has been caught with bag/foot

There is a green and a brown plug ensure these are right home incase this is caused by a loose connection at the Multiplug

Don't worry about the fault code U codes are communication glitches

If you need anymore help or advice on this issue please let me know

If you are completley satisfied with my answer /advice

PLEASE RATE MY ANSWER

Kind regards ***** ***** and have a nice day

Brian
