Engine fan Continues to run

Is this a common problem? My wife has a Mini Cooper Diesel with the BMW N47 engine. She has just 6000ks on the clock. At completely random times the engine fan will continue to run for up to five minutes after the ignition has been turned off. We took the car back to our BMW service centre and were informed that this is something to do with the regeneration of the converter that burns off carbon deposits.It was sugested that we take the car for a brisk run at high reves so that the process may be fully completed. Does this sound correct?

Seems normal. The PSA diesel engine does the same thing if you shut the car off either during or shortly after a regeneration. If the car is doing a lot of stop and start city driving you will have more frequent regenerations. Their advice to take it on the highway is quite reasonable.

If your coolant level is okay and coolant temperature is also fine, I see no issue.
