Advice please
I have a 2018 CPO E400 coupe that I bought back in 2021 with 30k mileage. Since having the vehicle it’s been a good experience just a few issues I’ve run into. I’ve always done service A & B every 10k miles.
Around 55k mileage my check engine light came on, it was a switch in the fuel pump that went bad so luckily the fuel pump was replaced by the dealer right before my cpo warranty expired.
Had to replace all tire sensors at one point. And my steering wheel stopped going all the way up.
At 80k mileage my ac compressor went out so got that replaced.
Now i just passed the 100k mileage and started getting a sensor for gas cap loose, I checked it and everything was good and it came off, but now the check engine light came on. I took it to auto zone and the code p0442 which is a leak in the evap system.
Took it to the mechanic and they did a smoke test and said the charcoal canister and purge valve need to be replaced and it would cost $880 to replace,but what worries me is they said when they were checking that out they said there was underboost and that the turbo needs to be replaced which is $3200. I understand that with any car, issues like this can happen but honestly I always thought these engines were solid if maintained and now I’m honestly not sure if it’s worth paying for it and expecting other issues to arise down the line. Can’t decide if I should just sell it as is or fix it and keep it. Any help is appreciated!
