Radiator Fan

Hi All

ive just got in from work, parked up, and locked the car.
and for a couple of minutes at least, the engine radiator fan kept running.
Is this normal behaviour, ive only had car a couple of weeks and have not noticed it before....

Thanks in advance

Mark

Perfectly normal my friend! It is the dpf regeneration process cleaning itself, it usually happens if you do a lot of short journeys!
Enjoy!

This is normal, part of the car cooling down its internals AFAIK.

I had the same thing... surprise and confusion when it first happened.... I never had it on previous cars so thought the car wasn't shutting down properly!!!

It usually happens after a trip when I've gone wide open throttle at least once.

Yep quite normal. If the DPF is regenerating the manual suggests you don't park on dry grass as it can get seriously hot... hot enough to combust flammable material that's close to the underneath! You can normally tell it's doing a regeneration as there can be a carbon/burnt rubber smell too sometimes. I was worried I'd knackered my clutch plates first time I smelt it, but now I'm reassured the engine's doing its job.
Fans normally operate on a thermostat regardless of whether the engine is on. When you stop there's no more air blowing over it, so the engine gets warmer, so the fan just kicks in for a minute or so just to keep it safe.
