Re: [MBZ] E320 fuel/electronic question SOLVED
Got the Mass Air Sensor (MAS) on Tuesday. Swapped it out in the parking lot while Daughter was working. Last night she said the car seems to be fine now. No more searching and stalling. As for the electrical problem: The turn signals/flasher and wiper are intermittent together, but are on different circuits. That is why I don't believe it is a fuse issue. It could be a ground issue under the dash, or somewhere else, or it might be a problem within the turn signal/multiswitch stalk. I plan to do some testing on Sat. Long ago I had weird problems relating the turnsignals and headlights, but I don't remember the symptoms now. I do remember I bought a used turnsignal/multi switch and that solved the problem.

You can open the switch up, at least on the newer ones, and clean up the contacts. The headlight part, anyway. Careful bending of plastic ears, etc...

Re: [MBZ] E320 fuel/electronic question
Are the old fashioned (only because they'be been around for 50+ years) better/worse/the same as the newer fuses that are like little flat plastic plugs? The more modern fuses are easier to see if they are blown - it's very obvious - while the ceramic fuses we all know can be *very* difficult to troubleshoot. Had a fuse a few years ago on our 78 240D - kept loosing the brake lights, etc - rolled the fuses and they'd usually start working. I chased all kinds of potential problems - relays behind the instruments - wiring under he fuse box - THEN I was looking at the fuses when my wife pressed the brake pedal - say a small arc in one fuse - there was a harline crack that was almost invisible to the naked eye.

Re: [MBZ] E320 fuel/electronic question
Yes, and I checked all the fuses last spring when it was doing this. If memory serves, these components are on different circuits, but fail simultaneously. SO maybe it is a ground problem under the dash? Last night was raining and near freezing. I want to try working on it inside, in the dry, with light, and preferably when it is not freezing. I found a couple of places on the MAS screen where the plastic was broken, but hanging at an angle, which could cause turbulence. Also, the oring to seal the MAS to the air filter box had been out of place, which might also cause some turbulence. I am assuming that turbulent flow might cause a false reading. We will try running it today. When i worked on the car this summer, I did not remove the air cleaner top from the MAS body. If I had, I would have found the oring out of place. Is there any way to test the MAS out of the car with simple equipment? Ohmmeter or voltmeter... At 09:37 PM 11/11/2008, you wrote: Fuses?
