I would also check that your thermostat is working okay as I have read numerous threads on here where it has malfunctioned. This could lead to over fuelling if the ECU doesn’t think the engine has warmed up. I don't really know about setting up the throttle body but think you may need something like VAGCOM to make sure it is set up correctly?

Have you changed your Air Filter lately ?
