I looked down closely with a light, and nothing is broken on the tumble flat actuator mechanism, it is easy to move with my finger, so its not seized, the car works perfect as well,
so my question is, when the tumble flap sensor comes on, and the car is working perfect, idle/hard acceleration Am I safe to assume is it actually just a faulty sensor? also a local mechanic tried to get a reading on the scanner for that sensor and it was basically blank, so he concluded the sensor wasnt reading anything, thusly, faulty.
any confirmation or input would be appreciated, no local benz dealer so not even sure where to get the sensors.
Also, i am not having very good luck tracking down the sensors online, one would expect it would be called "tumble flap sensor " but no luck ,,, any help with part number would also be appreciated
tumble flap seems to be a common issue to break on this era mercedes, it changes the angle or lenght of the intake runners depends on any given throttle, its based on vacuum. At least this is my understanding.
so my question was, given i can see the external linkage is not broken, but i do have a code coming up(as seen in picture) how likely is it that is is the sensor gone and not an internal issue,
also, am i right to assume that when the linkage is broken internally the car will run rough at idle? or higher rpm, depending what position it is broken in
also, i am not having any luck locating this sensors on any online parts sites
sorry, since i was in the e-class thread i overlooked putting the year and such.
