Hi - I'm on my third S type and I've had several problems including stuck on parking brake, Restricted Performance messages etc and, I'm lucky but, in every case the problem has been caused by cold weather, short journeys and consequently low battery voltage (11.5 this morning!). A substantial recharge or battery replacement has cleared the problems and reinstated my faith in the car. My current car is a 2006 diesel and came to me 3 weeks ago from a dealer. It seemed to have been well looked after but a Restricted Performance message caused me too doubt. I think for people new to the cars or others who contemplate replacing EGM units etcit may be a cheaper first check.
