The cool wail
The heater of my 5yr old Diesel 2.2 Nissan X-Trail T-Spec has never been much good and only starts to give out heat when the engine has warmed up after 10-15mins of driving. This is a real nuisance in severe winter weather because I can't use it to defrost my windscreen. My partner's petrol MINI One has an excellent heater and her car warms up within a few minutes and certainly long before the engine reaches its optimum operating temperature. Should my heater work better than it does?

This is true of diesel engine generally because they are more thermally efficient than petrol engines and that means they take longer to get hot.
