Front Radiator Fans

Due to engine bay noise, I just had my 2006 C2S water pump replaced. In addition, my car had some software updates required by the factory.

Now my front radiator/coolant fans seem to turn-on all the time. Before this service, I rarely noticed them coming on.

Is this normal? Did the dealer mix the pure coolant with too much water? Did Porsche change the process for this with one of the new software updates?

FYI, my temperatures are all normal. No changes.

Let me know what you think?

You probably have service action W737 done. This is DME programming update to deactivate the lowest speed setting of the engine compartment fan. I don't think anyone knows exactly what this update does to the DME but I guess its possible they use the radiator fans to make up for less cooling in the engine compartment. I would think this would have more to do with any noticable changes than anything related to the water pump replacement.

If the fan issue persist, it is appropriate to repeat the DME service action with the latest PIWIS up date, in the low speed mode.
