When I switch off, from outside the car, I can here the computer closing down. No problem, but
lately it is getting significantly noisier inside the car, approaching irritation level! Is there any
way I can make it quieter??..............please!  2013 Dynamic Santorini black

Oh mine does that too. I was under the impression it was the throttle body re setting/adjusting itself. It is quite noticeable. Even my next door neighbour has commented on how loud it is!
