I'm going to swap the egr and turbo transducers as soon as I get the silicone vacuum hose I've ordered.
I suspect the egr transducer anyway because the egr valve seems to be acting up. And the turbo was working fine on the highway and then no boost. Instead of going 75 all the sudden I was going 60 and no power. I did check the turbo output to the intake manifold and didn't find a breach. So I suspect the turbo transducer as well.
The vacuum hoses on the car are suspect and could be an issue as well.
The scanner I bought is a BAFC products Bluetooth OBD2 Scan tool.
Can't get it to communicate with the Mercedes but it works great with my Buick. The scanner is supposed to work with all cars sold in America from 1996.
But I hear it might not be up to task for a Mercedes diesel until 2001 up.
But the old school disconnect the battery didn't make the cel go out so I suspect a short in one of the sensors. And that's why the cel won't go out.
I'll chip away at this. I know I'm not the only person who's having this problem. I know it has to be something simple. Once found.
