This past week, it would come on and stay for a while, and my idle was rough. Then yesterday, when I went to start it, I had a really rough idle and CEL stayed solid. This morning I checked under the hood, and I didn't see any obvious intake leaks, tightened up my intake boots and it ran a bit better but still rough. I checked the CEL code: 1215 MAF. I checked the voltage on the connector (not the sensor) and it had voltage. I happened to have a spare MAF around, so I swapped that out. I started the car and it ran better (not great), but CEL still on. Drove it around a bit, and idle is fine, but CEL is still on. I tried the hold the pedal down for 10 seconds after pulling the codes, but that doesn't seem to do anything. When I pull the codes, it just seems to repeat them over and over and over again. So I hold the pedal down for 10 seconds turn the ignition off, and check again, still showing 1215. Do I still have a MAF issue, or am I just not clearing the codes right? Any clue? Car is a 94 540i with about 170,000 miles on it. It definitely could use some work, but in general the engine has been running like a top. Thanks in advance for the help, and happy holidays!
