As everyone else seems to be having problems with theirs... my park sensors and reverse camera has gone on the blink. It's not all the time, just seems to be when I most need it

It'll be a few month yet before going near a dealer for the service stamp, so if it's something easy enough to check then I'd like to give it a go. But from a quick snoop underneath I'm wondering if it'll be a front bumper off job to check the sensors? Or is this something to leave to warranty, I'm starting to build a little list of things failing....

I've got the error code as below on the IIDTool B1B38-26 Front Inner right sensor.

Thanks
Dennis
