I get a trouble Code PC155 and PC146 - without any further description by Durametric what it could mean, seems to be a non-OBD-Standarc-Code by Porsche.

At the same time I now have the enging compartment fan running once I start the engine - all the time!

The fan connection itself seems to be ok, testing it with the Durametric tool once the engine is off goes well, it goes on and off, so the fan itself and it's power connection to the DME seem ok. Can only be the temp sensor I guess.. would be extremely helpful if someone would have the meaning of the above rouble codes to cross-check..
