Code P2755 transmission fluid cooler control circuit high

[Asad]

Hi. I have an Audi A6 C7 2012 auto s line 2.0 diesel.  I had an Engine management light on recently with this message and code. P2755 transmission fluid cooler control circuit high. It goes away some times and comes back. I cleared the code with obd11 and it went away for a day but came back again. anybody can shed some light in what this could be please. is it a serious issue? The past few days I have been driving and I felt the car jerking when it switches gears around 3 to 4. it bogs down then picks up. I scanned again for codes and got the three following:

throttle position sensor
brake pedal released
air quality sensor

Am not sure if these could also affect the experience driving. other then the air quality sensor I don't know what the other two do. Please could you provide assistance. 

 

Thanks

Going from the original scan, when was the gearbox fluid last changed? If it's the dsg gearbox the gears can be affected if the oil is degrading. 

The throttle position sensor is more likely an issue I'd say then the others.

Hi the throttle position sensor is most likely the throttle body gunged up  the other two are random and would not affect the driving of the car also look at servicing the gearbox, new filters and oil.

Hi thanks for the reply. I will be looking to change the gear box oil. the attached picture is that a dsg gearbox? the oil that I need is it a normal cvt gear box oil? 

 

Thanks

Not sure which oil you'll need but CVT is a different type of gearbox to dsg. Here's the oil change and oil type of a CVT:
