There are many suspension issues ! I have a 2 liter hdi on a V, it had hard spheres so instead of messing about I changed all 4 and now it feels like new, the sheres are only £35 for a pair and easy to do. Regarding the fan, are you sure it isnt the air con fan as this will operate even when the car is cold as its cooling the condensor, if the heat setting is on demist in the car it automatically puts the AC on thus kicking the fan in. Sounds like its normall so just leave it, n buy a wig!
