Ok, MPS look similar but there are different serial numbers for Mercedes depending on the engines, these are for the 280, 350 and 450 engines, ending in 110, 111,112 and 012, those are the last 3 numbers on the Bosch reference.
You can´t mix them as they have different reostasts inside. The MPS just senses the vacuum pressure on the intake and sends a signal to the ECU so it knows the exact quantity of fuel that needs to be injected. To test it use a multimenter and you have to get 350 ohms reading.
