Hello, so I wanted to unscrew my MAF (LMM) from my w124, now I have these screws hindering me from extracting the sensor from the tube. How do I open them? What can I use?
It’s a w124 CE320 with the m104 engine from 1992.
Thank you so much
Edit: couldn’t open it. Sensor is clean. Issue still there. Thank you all for your help and insights
TL;DR: W124 MAF sensor - OEM or is an aftermarket part fine?
Hey guys, I’m having an issue with my 1992 C124 (M104 engine). It sometimes stumbles/sputters at idle during both cold and warm starts. I pulled the codes on the old man, and apparently, it’s showing misfires on cylinders 4 and 5, which doesn't really make much sense. Spark plugs are relatively new.
Anyway, straight to the point. I was just about to order a new MAF (Mass Air Flow) sensor, since I strongly suspect that’s where all this nonsense is coming from. But now I'm seeing that the Bosch ones are €530, and on the Mercedes website, they’re over €900. Since my funds are tight and my last name isn't Bezos, I wanted to ask if anyone has experience with aftermarket/non-OEM parts, and if so, which brands?
Also, if anyone has any other ideas as to what else it could be, I’m all ears. Thanks in advance!
