Recently moved to the Mercedes fold from a long line if BMW's and unfortunately already have a rather annoying issue!

If I switch the car off a minute later the engine cooling fan turns on to its full setting, ie very loud. It will then stay on until it kills the battery. Nothing will stop it apart from pulling the connector on the fan unit!

The problem happened after disconnecting the negative terminal on the battery for a few minutes and then reconnecting. Was fine before. Only thing to note was the car has recently been stood for a month ish and afterwards had been subject to a lot of starting up and shutting down after needing to shunt cars on the drive around.

Any ideas? Im stumped!

Thanks
