replaced the thermostat with a factory Nissan OEM thermostat. Completely fixed the problem..
Pros: completely fixed problem

I have an 06 Audi A3 2.0T Sportback with just over 105k miles; recently replaced the thermostat, spark plugs and coil packs. Other than being in need of some new brakes and a bit of cosmetic love, she's running strong.
Pros: running strong
Cons: needs new brakes

I’ve had so many replacements fail in all my Nissans over the years that I just get an oem one from a dealer. Never had an oem one shit out yet.
Pros: OEM reliable, no failures
Vehicle:
Nissan
Since going with the OEM thermostat, my temp gauge has stayed pinned just below the middle of the gauge, even towing campers and heavy loads on hot days.
Pros: stable temperature, handles heavy loads
Vehicle:
Nissan
Only an OEM Thermostat fixed it.
Pros: fixed issue

I had this exact issue with 3 aftermarket thermostats that were opening too early. Bought one from Nissan and my temps went back to normal
Pros: temps went back to normal
Recently had the exact same issue on a 14 a6 ended up being a DOA t stat I compared the shaft length on the new t start to the 2nd new t stay and sure enough it protruded out about a mm further just enough to not seal properly causing the over cooling after the swap no more issues.
Pros: no more issues
Cons: over cooling
Vehicle:
Audi A6
Had this happen to our 2018 Q5 a few months back, 35k miles on the SUV. Thermostat issue plus some other stuff.
Vehicle:
Audi Q5
Mileage: 56327 km
I recently changed my thermostat due to my temp gauge occasionally dancing. The old thermostat appears to be bypassed as theres no actual thermostat in the housing. After putting on a new nissan one and oem gasket i bled the system with a overflow funnel for about 40 minutes until i stopped seeing bubble. Also using peak 50/50. Afterwards my overheating problem has gotten worse i overheat in about 10 minutes. I tried bleeding again and same results.
Cons: overheating problem worse
