Woke up to P07B7 on 2020 C43
Back story: the car has been healthy, runs fine, sitting at 58k miles. Yesterday I woke up to a P07B7 light (pressure sensor implausible fault).
Car:
Online reports say it’s just one sensor on the valve body and the specialists can fix the sensor for some $500 bucks.
Took it to two indie shops and they both say they can’t do it because it requires a Mercedes coding and I’ll have to go to the dealership anyway.
Dealership valve body replacement is $4000 for parts and $2000 for labour.
Another forum member mentioned used 9g replacement is just $1500 and $3000 labor - but coding might be an issue again?
Oh and also, I replaced the transmission fluid in Feb this year and one of the indie’s mentioned the fluid is black.
Any help is appreciated
