2007 Sprinter 311CDi EGR
Absolutely fascinating thread!
The EGR valve on my 2007 311CDi has stuck in the closed position. It's totally seized. The van is in limp mode and is reporting an error code of P0404.
I have electronics/microcontroller/PCB making experience so am pretty confident I can design & build and emulator which could fool the ECU into thinking all is functioning as normal. The only(!) thing I don't have is the knowledge of exactly what the ECU needs to see.
I believe my MAF is a frequency modulation type but this should be pretty easy to spoof using a small microcontroller.
Can anyone please tell me what The ECU expects from a working EGR and MAF sensor? I'm going to have a sniff with a logic analyser this weekend but it would be great to have a head start.
The EGR is a Wahler 00005320C5 and the MAF Sensor is part number 000 094 32 48.
Assuming I get a workable solution, I'd be more than happy to share the results!
