Hey,
So this is my first time using this forum or any actually, but ive exhaused every option i could think of, so though why not reach out here and see if any of you can help.
Recently bought a 2013 VW CC 2.0T with inly 68k miles on it got it for a great price since it had been in a minor front collision. Ended up replacing Rad support, rad, fans, intercooler and ac condenser, car ran for about a week then i noticed the fans were constantly on and that my Temp gauge was constantly not rising. Figured thermostat was stuck open for some reason or another ended up changing out the thermostat with third party piece and flushing the whole system but still not change. Maybe it was a faulty one, so replaced it again with OEM one that i bought at the local dealer. Still no luck, car holds temp great when parked at idle, as soon as i drive off it just plummets. Took it to the dealer the for diagnostics couldnt figure it out said they have to start ripping it apart to find the issue and start by replacing the radiator and that I would run 3-4k to find the issue. So basically they wanna play a guessing game and charge me for it. I ended up replacing the radiator myself and still running into the same issue. I was told by a local mechanic it may be because i don’t have the engine splash shield which didn't sit right with me. So at this point i dont even know where to start to locate the problem. So any suggestions welcomed!!

Thank you all!.

You mentioned that your fans are on constantly. If that is still the case, that is your problem. If they run constantly the car will have a hard time warming up and retaining operating temp.

So heres the thing, i figured as much but they've only recently been constantly only a couple of weeks ago they could only turn on when the car reached about 210, 220 degrees F ,parked. Which they should. Yesterday I tried disconnecting them waiting for the temp to get to that 190-200 mark and taking it for a drive down the road and the temp still drop to almost to nothing.

Your next step is to acquire VCDS (or borrow a friend's) and run a complete scan of all DTCs, save the report and erase the codes; then drive the car for at least one driving cycle, and scan again, and post the report here so we can help diagnose the problem. VCDS is the only software that is designed specifically for VW vehicles: in fact most dealer service techs and independent specialists use it instead of the VW one because it is faster and easier to use. It's not cheap but the approx. $250 will quickly pay for itself.
Keeping in mind the front end accident damage, I suspect a wire connector to a temperature sensor loose or not properly connected, causing an intermittent electrical problem when the car is in motion; but this is once again guesswork, of which you have already done more than enough. If you really want to solve it you need to use the appropriate software.

Just curious, when you're refilling the cooling system, are you pulling a vacuum to get all of the air out? I was having similar issues to what you're seeing because I wasn't using the vacuum refill method. As soon as I filled the cooling system using a kit from ECS, the problem went away.
