Code 0100
My '01 E55 has ~110,000 miles on it. It started running very rough recently. Terrible gas mileage and throwing a 0100 code consistently (erase it, starts up without it, then comes right back).
Has anyone had any experience diagnosing a 0100 Code (MAF or VAF A Circuit Malfunction)?
Replaced the MAF about 12,000 miles ago (whole thing with a Bosch part; not just the insert). Since I started getting the 0100 code I took out the MAF and cleaned it with CRC MAF cleaner (didn't take the MAF apart).
Any help is appreciated.

That's
a circuit problem,not a cleaning problem.You need to check power to the maf,any loose or frayed wires,Make sure the socket is plugged in.Bosch part off ebay or a real bosch part from someplace like autohausaz.com.?Someplace the maf system is not getting the whole 5 volt signal,,,,,you need to locate where.Any friends near by to swap out the maf and see if it has a gone kaput circuit?

Bosch MAF from Autohauz.com
The one I replaced ~12k miles ago was a Bosch MAF from Autohauz.com. I have a neighbor with a 2001 E320...will it have the same MAF???

So
as suspected ---- swap out the maf and see if it has a gone kaput circuit?---
The Maf circuit was kaput and Autohausaz.com replaced it no problemo
Now you can get back to kickin butt and takin names
That has got to feel great!
