Went for some diesel today, got back in the car started her up and radio has no sound.
Turned radio on and off and still no sound so endured silence on the journey back home.
Once home I shut the engine off and restarted, now no radio sound and the sat nav screen is blank
Left the car for a couple of minutes and restarted again and everything is back to normal
Anyone else experienced this weird behaviour?

Nik. 2015 Golf R DSG
Gone 2013 Mercedes C220 CDi AMG Sport Plus
Gone 2008 2.7 RRS HSE

Just the normal electrical gremlins. My satnav screen has these little wobblies from time to time and the wing mirrors dip in reverse only when they really want to.

Characterisiic I think the service guy called it............. FF 4.4 V8 Soooo looking forward to this bad boy
Ex 2006 RRS SC - garbage
Ex 2016 135i M Sport - dream car
Ex 2003 RS6 Avant - piece of cr*p
Ex 2014 320d X Drive, M Sport Touring - ok I guess
Ex 2007 RRS TDV8 - bloody loved it

Yes, yes, it happens once in a blue moon. No idea why.. But the next morning, it's recovered from its little tantrum, and all is happy and wonderful!
