can someone help me please? My VCDS reports error 005644 coolant pump 2. I don't know anymore. The pump turns on, but after a while (10sec) it turns off and the error code starts up. Cables are in order, I checked the fuses and relays.
Is it normal for the Group 139 thermostat to show -48 ° Thermostat ? I'm looking for some connection.

Have you decided the problem? I've changed the turbo cooling pump, it was damaged ( antifreeze in the electric part on pump). But still have 005644 error...
