Hi having found a site that actually works......brilliant few more  questions 

my Audi smokes at standstill not white smoke.........and my handshands free was working stopped  at the same time as my keyless entry and start etc  stopped any quick fixes? Cheers guys

I know it sounds silly and even slightly dangerous (wouldn't advocate sniffing exhaust fumes for a prolonged period) but does the smoke smell of diesel fuel or burnt oil or even coolant with sweet smelling antifreeze (sounds like I have some sort of addiction going on here!) ?

Maybe a battery reset or signs that the battery is failing....happens like this with top end BMWs.
