I am new at this forum and sorry I can only write Englisch. German reading is no problem so you can answer me in the German language.
First some information regarding my car. I have a 2.5-16V with motor M102.990 with Kat. We did a complete overhaul of the motor and of course we needed to replace the air flow sensor. I have ordered a new one OEM number 3427 224 035.
When installing the sensor we measured the resistance which is totally ok in the beginning (value of 1020 ohm) and graddually increase to 9 kOhm. According the Mercedes manual this resistance should decrease when the airvalve is 3/4 position. This is not the case with me and the values increase up to 11kOhm with full air valve down.
Does somebody has any experience with adjusting the sensor.
Many thanks.
