Hello everyone!
Got an 08 C300 4matic about 2 weeks ago.
About a week into owning it a CEL popped up while driving. Got home and scanned and found the P2629 staring at me.
It was on for about 2 days before I had wiring and socket checked out and then proceeded to replace the sensor (Passenger side upper).
Before replacing I found that the code would not erase even for a few secs and after replacing, the code erased but returned soon after and this time, it appeared with the P0050 which points to the corresponding sensor on the driver side.

Now I am stumped thinking this could be something else and not the sensors.
Are these sensor heaters fused??

 

Nobody?

 

I guess it depends on how you interpret the last paragraph in this document:





I will also leave this right here:




There may be other related documents that I can post, but I gotta run for now. I will check back later on....
