Does anyone know what the genuine Mercedes Bosch resistance values are. I had buy an ebay £22 MAF to replace my 16 year old genuine Merc one that seems to be playing up. However it seems as though it has a slight rough idle at times and may stall the engine under braking at times. When turning it also makes the engine run very rough and lower idle speed.


Checking DAS, I got
P0130 A O2 sensor upstream TWC (R22)
P0100 Hot Film Mass Air Flow Sensor (B41)
P0325 Knock Sensor


Results for old worn out Genuine Bosch 0 280 217 114 Merc 000 094 09 48 MAF (insert part No. Bosch F 00C 2G2 025)
Terminal Pins 1 and 3 = 1.52k ohms
Terminal Pins 1 and 4 = 6.02k ohms
Terminal Pins 3 and 4 = 4.50k ohms

I have now ordered a new genuine bosch MAF.


Does anyone know the genuine part number for the O2 sensor causing the P0130 error.
