hi,been the owner of my first x type for 5 months now,a 2002 2.5 petrol ....no problems till this weekend....when I turn the engine off,theres a sound like a fan still running under the bonnet,which can last for around 5 minutes,the only way ive found to stop it is turn the engine on and off once or twice....bit worried as I use the car to commute daily...going to ring my local garage this morning and take it down ...passed m.o.t last week,no problems...any members know what the problem could be,thanks for any help,simon.
