Radiator fan permanent on query on C200

[C200 goblin]

Hi all
Just being wondering if anyone knows if there is an electric module controller for the radiator fan on a 1998 C200 automatic.
I ask this as I have been told by Mercedes Benz dealer that there is not, and the only thing controlling the fan they say is the viscous clutch drive behind it.
But when I checked in the Haynes Manual, and pulled back the nearside inner wheelarch liner (removing the roadwheel), I see the fan controller they mention in the book that is just around a ciggarette packet size. Not wanting to take it back off again, does anyone know this part number. If so would replacing this instead stop the fan running permanently on when the ignition is switched on.
I have replaced the coolant temperature sensor that goes in the bottom of the header tank and also cleared out the header tank and there is no blockage or air lock in the system, but it is still going off.

Found out they were telling me for the wrong model, it does have a fan controller.

I would hope that by now either the motor has burned out.. The car is no longer owned.. Or the dealer actually managed to repair it..

It is a well known fault on the 202 where the rad fan controller fills with water.

You just replace it,,, it was possible on some if caught in the early stages to dry them out and re seal them, but this one will be too far gone.

Sorry I did not see your original post I was not a member back then

I did solve the problem. I had waste money on the fan controller but it was the coding of the EIS ignition switch module that had the car not recognised as a W202 saloon or Right Hand Drive, which makes you believe its the fan controller making the fan run at full speed.

Errors in coding are not something thats easy to deal with, we would never get that in another 7 years
