Just had the local dealer read the error codes for me.

Code: P0100-001 B2/5 (Hot film mass air flow sensor)
The signal voltage is too low.


This is just one of several codes stored...

Vehicle went into limp mode last week... (that's why I took it to have codes read.)

No mention of any problems with transmission on the printout of error codes.

My question is this... Is the mass air flow sensor the same for the diesel engine as it is for the petrol engine.?

According to the printout the mass air flow sensor in my car
is referred to as: B2/5
I had a look at the russian mercedes web site and the
part number of the mass air flow sensor for my model (ML270 cdi ) is: 611 094 0 048

Is this the same part I see for sale on various web sites in the USA where you mostly drive petrol engined ML's... ?

Looking forward to your comments/input/advice.
