Default Thermostat Question

Hello fellow Audi owners. I have an '02 A4 Quattro w/ the 1.8L Turbo. I have a P1296 code and have replaced the CTS. The CEL was re-set and reappeared after a couple hours w/ the same P1296 code. I am looking at replacing the thermostat as the next step. My interior temperature guage stays near cold for the first 30 minutes or so of any drive, then the needle usually heads toward the center of the guage. It often then heads back toward the cold end about 1/4 of the way between cold and hot. The water pump is working fine and the anti-freeze level is appropriate.

1. Do you think it's a thermostat issue?

2. Do I need to replace just the thermostat (~$20 part) or the whole thermostat housing and assembly (~$100 part)?

Thanks in advance for your feedback!
