I was wondering if anyone can confirm if these are the correct part numbers for my car (1.9 tdi pd 105 bkc) 

Coolant temp sensor 06A919501A

Thermostat 068121113H

Thanks

As parts are 'modified or upgraded' regularly the best advice is ring the dealer and quote them your registration number and they will tell you the correct part number. Sometimes you will find numbers the same but then with different letters on the end like A, B or C and beyond where they have been changed. Aftermarket parts can give issues particularly those that need to be 'adapted' to the ECU which the Coolant Temp Sensor may need to.
