Locating the Coolant Temperature Sensor in Audi A6 C6 2.4 V6 - Rich Mixture Error

Hello. I got a motor error. After connecting the computer, it shows the coolant temperature error and too rich mixture on the cylinder 1,2. I bought a new temp sensor (4 pins) then together with a mechanic colleague we dismantled the engine "pol" in search of this sensor and nothing: / I would add that we were looking for it with advice from forums with photos etc. On all photos it was behind the engine on the left under pipe. Unfortunately, there is nothing like that here. For me there are 2 temp sensors (2 pins) what do you think ?! Anyone know anything more? Can I name those? I will add that the car has good and good workmanship and even 2005 thanks in advance !!! Regards

Did you check here?

Hello. Yes, I have it here, but 2 pins everywhere write that it should be another 4 vertical and so also sold to me in the store for my registration: / and there is no such. But I was just thinking not to mention it?

according to ETKA, it's how you write. Black sensor with two pins Catalog number: 06A919501A or 06A919501

So the 2 vertical to be replaced from the photo? And that is not in this engine? Thanks a lot

Hi. The sensor mentioned, however, the error showed again is 2 days and 2 days are gone: / maybe someone else has any idea? Thanks in advance
