Hey everyone! I have a Audi A4 evant 2.0ltr TDI S LINE

Has anyone experienced problems with the doors not opening from the outside? I can open them from the inside & then there fine until i lock the car again. This started out with just one door & now all of them are doing it, mostly the drivers door works but can’t open the back ones at all without doing it from the inside and the passenger door is intermittent. 
 

Engine management light is also on with code P2015 which is the inlet manifold, I had the actuator changed but still the same code so am looking at getting the whole inlet manifold changed if anyone can recommend a dealer to buy the part that would be great? 
 

My only other issue is the screen wash that does the headlights is missing a part so it just goes on the floor, my screen wash doesn’t work at all but I’ve ordered a new motor for it. 
 

Thank you.
