can anyone advise please I have a box under car with a flat pipe coming from it every so often it blows off can anyone advise what this is please

More info needed- where is this box on the car (front, rear, middle, passenger or driver's side) and what does it look like? Is it a metal, plastic or rubber pipe that goes into it? Does the pipe just carry air, coolant or fuel etc, and is it a large or small bore pipe?

Could be the auxiliary heater.

That's the booster heater standard fitment to the diesel versions, fully automatic unless you have the independent heating option

Aids faster warming up during the cold weather.

thanks chrispb123456 what does it do and how does it work thanks

It's purpose is to speed up the warm up time of the vehicle- it is a fuel fired additional coolant heater basically, without it it is purely the heat from the combustion in the engine which warms up the coolant, but being a diesel engine, this can take a long time, especially in cold weather- which means that the cabin takes a long time to warm up (the heater will not blow hot air until the coolant is up to temperature) and the engine also takes longer to reach operating temperature- and is therefore less fuel efficient and maybe more prone to wear. The booster heater reduces warm up time in cold weather and allows the engine and heaters/cabin to warm up more quickly!
