Recently plugged in my obd2 and it showed up P0236 and P0238. Turbo boost sensor circuit range and circuit high respectively.
I have also noticed my auto gear change has become temperamental and sluggish. ESM button doesn’t work and nor do gear change paddles.Are these issues related and what should I do to address them?
I reset the transmission which seemed to work but things have gone back to how they were and cel is on too.

i have no idea what car you have or how old so i will start with get your battery checked , dodgy battery will throw up random errors or Replace the boost sensor

I have a 2014 cla 220 cdi. 170bhp model.
I have a boost sensor on order. Would the boost sensor indirectly affect the auto transmission?
I did the reset which worked but things have gone back to how they were and now I have a cel light coming up too.
I will change the sensor then go from there.

I would still check the battery as a first port of call after doing the sensor as these cars are just a bunch of electronics on wheels
