I had this click issue. It was a failing starter.

Likewise, new starter under warranty at 11k miles. Only did it intermittently (at the pump in a busy petrol station, trying to get off Eurotunnel etc.).

The issue was not a "click" rather a half second starter sequence! So more of a "miss start" than a "click" from the starter solenoid...

It's happening to a friends 11MY AB Black... Get in, press the brake and the starter button. Then the engine will turn over for half a second or so (not long enough for it to start) then stop! With your finger still firmly on the starter button!

I could understand if it was just a "click" That would be easy!

Im sure i read a thread on here somewhere about someone having the same issue!

Wasn't a solenoid noise, starter just didn't spin up. Surely not difficult to check the feeds etc. in a workshop.

No, obviously it would not be hard for me to book him in but!!! I am very busy at present and kind of remember reading that thread which would have given him some information to have a fiddle on his own time (as thats what he likes to do)
