Hi, my 2006 x-type 2.2d has just developed an intermittent fault when driving. The sat nav display and radio & mainbeam switch off then the battery light and airbag light come on as if something has reset. I also here a relay clicking from the passenger fuse box around the same time. Once it starts it occurs often. I have tried reading fault codes but none come up. Does anyone have any ideas where I should start looking?
