Is anyone able to help with these vag-com errors?

Every couple of days my engine management light will come on and stay on for a day or 2 and then turn back off , car drives fine, no limp mode etc, recently drove the car 200miles with no issue

Its an Audi A4 2.0TDi 2010 B8
I ran vag-com but cant get an accurate diagnosis on what the 4 problems are and how to resolve
any help is greatly appreciated!!

No I take it then

Thanks!!

I know the sensor needs changing now

I haven't noticed any problem with the rocker switch so il test it out

I've cleared the fault and it does come back, although since I have noticed that one of the rear windows switches does work from the back just the front

I will do the optical tests and post result

Cheers

Yeah I'm getting booked in to do sensor on Wednesday as have read how much it can cost if ignored
