L322 L322 battery and electrics

OK, I've just been rescued by the RAC because the battery I've needed for ages finally died in the 2004 L322 3.0 diesel. All my fault.

The RAC man insisted that there was an electrical fault because, when he closed the doors with the key out of the ignition, he could hear a fan running somewhere in the engine compartment.
I said it had always done this and yes, the fan does run for a short time when shutting the car up for the night, but it stops after a very brief run. He insisted that this was wrong.
His report states that the current drain at this stage, with the fan, was 2.2 amps and it needs to go into an auto electrician.

Can anyone confirm whether, when parking and locking the car, there should be a brief period where a fan runs?

Thanks. I'll assume it's OK, and the RAC was wrong.

I'm a bit under the weather after lung drainage (1.2 litres!) so will have to get a local garage to supply and fit the battery.

The breakdown report notes the following: " battery failed test but car also has high current draw of 2.3amps memebr declined replacement battery advised of charge to reattened", which implies an argument if I call them out again in the near future.

I think the fan sound does come from the region of the fbh, so presumably that does have some sort of short period of safety cooling just in case.
