GL350 diesel bluetec
Angry GL 350 diesel pressure differential

I have a 2010 GL 350 turbodiesel bluetec

I went to replace the pressure differential - it is a dual pressure switch. The one I replaced on my daughter's car was a single & it works fine. Why does mine have a dual switch & will a single solve my low power issue?

Instead of the single differential switch it has two side by side clamped together. I will attach a photo.

Can you view the photos I posted & tell me why I have this dual differential pressure switch. And do I need to go to the dealer for this part? I have no power when accelerating. I replaced the turbo already.

OK, this is DPF pressure differential sensor.
If I understand your question, you ask why different model has different sensor?
MB is constantly improving their cars and lot of parts has several updates.
Still remember W124, who for given MY had 7 different engine temp sensors.
It is what it is. Do you have a code?

the code is P0299. My confusion is - the part I ordered & received to replace this with the specs for my vehicle is a single (not dual as pictured) . I'm wondering if the single will work. The part I received is a MZD part with MZD # on it. I am installing it on the rear sensor.
