Hi

Help needed if possible

I returned home after a 100mile journey nipped in the house for ten mins then jumped back in the car, inserted the key and nothing happened!!

No steering lock unlocked no ignition lights no electric seats no mmi system ! Nothing

I've rattled the gear shift its def in p

I've checked the battery it fine full 12v and interior lights etc work

I've tried the spare key

Checked the fuses I know of

Has anyone any idea or history of this problem they can help with please?

The AA nice man has concluded it could be a dash failure or ignition switch problem

Help please?
