Audi A6 S Line

[Laura Winslow]

Hi there I’m having a few problems with my 2014 Audi A6.

So as far as I’m aware the lights are all LED. My left rear strip of light on the boot has not been working then all of a sudden the indicator on the boot is flashing fast and no where else, anyone have any idea what I can do? 
Also, it’s telling me my pressure sensors are off, I hit a bad pot hole a while back and ever since then it’s been showing that up on the screen and the traction control is off too.

Final problem (promise) my heating in the car works on the passenger side but not the drivers side, passenger side pumps out lovely hot air, drivers side icy cold air, if I sit with the car running after the thermometer on the engine is fully hot it will heat up on the drivers side but once I drive off again it cools. I can hear the thermostat constantly clicking in and out so not sure what that’s about. 
I’d appreciate any help, thanks 😊
