When my headlights are on the boost gauge no longer lights up. I'm not sure if anything else  on the dash is affected yet.
It was going on and off yesterday & today has given up.
Any ideas?
I'm taking  the car away next week & I don't want it short-circuiting anything else if there's stray wires.
Second problem on this car and it's less than 5 months old. Not a single problem in my old one.
Just need to know if it's dangerous / likely to cause me problems (and what's the problem would be useful!).

Cheers guys

I've noticed this on my gf's 2010 esse esse, is there anyway of stopping them switching themselves on and off?
annoying when I've pinched it and out on evening blast!!
