Hello all, I have a w168 with MSM VDO 1.4 ECU. There is error p0100 stored in the ECU. Ecu Testing in UK tried to test the unit they told unrepairable as their MB software wasn't getting live data from MAFS. I received the unit back, cleaned the mafs, refreshed solderings and cleaned the air mass temperature sensor. Live data from MAFS is present as I can see it with my obd scanner, air temperature reads some degrees less than outside temperature, 7° instead of 10.5°. If I clear the DTC it comes back. The sensors on the mafs are clean and don't seem to be damaged and the readings are there. Ideas ?
