I tried to fix my p1121 error code by replacing the 3-way coolant control valve. I even got OEM. I ended up spilling all the coolant on the ground. I also had to take one of the hoses off the coolant pump which I then forgot to put back on when I started the car. I then put it back on once I realized my mistake. I have refilled, and possibly overfilled the coolant system but the coolant doesn't seem to be circulating. The coolant system also seems to be making a weird noise like it is trying to pump and getting nothing? Could there be air in the system? I am having the following error codes now: P0117 P1121 - still, even after clearing code P0A0D - I triple checked the service plug and I am pretty sure its all the way in and pushed down! The red triangle goes on and off. Any idea what the problem could be? Did I break the pump or put air in the system?
