Buying a Mass Air Flow Sensor......

I have a 99 C230 Kompressor, I just received a refund off of a FleaBay Scammer who sent me a bad sensor and am about to purchase a new Bosch on Germanstar.net....the only question I have is they only sell the actual insert. The Ebay craphead sent me the WHOLE cluster where the insert goes into....if I purchase the insert, is this going to solve the MAF problem? Or do I need to purchase the whole cluster to solve anything? Also, when I do receive this, I read that unplugging my engine for 10+ minutes should reset my computer to clear any check engine codes....is this advised or a myth? I will give the first person to reply the biggest thank you in the history of man!!

LOL, no thanks necessary. Anything you buy from GermanStar should be fine, just make sure you find some instructions on the proper way to swap the inserts. I don't know the right way to clear codes by d/c the battery but after a few on/off cycles of the car they should clear themselves.

The MAF we've got from GermanStar come mounted in the tube that didn't fit MB. I think it was originally design for VW. That is actually good thing, because the tube gives protection for very fragile MAF during shipping. 2 screws with proper bit take seconds to remove.
Took me 7 restarts in 10 seconds to clear CEL with new MAF.

Hi, Jeff. The insert (when purchased from Germanstar.net) is fine to use, that's the business part of the MAF anyway. You can reference the DIY to clean it in the W210 forum, same thing to R&R the insert from the assembly. The new one comes with regular screws if I remember correctly, but you'll need a special security torx bit to remove the old one. However, you can just use pliers to unscrew them, the screws aren't that tight and they have a nice shoulder you can grab with the plier teeth. Then use the regular ones to reinstall. It only goes one way.

Take care and enjoy the ride,
Greg

If you dont have torx security bits, harbor freight sells a set cheap. As to the CEL, you can have it cleared at autozone or advance auto. Anyone with an OBDII scanner can do it.

Or you can simply ignore it and drive normally. After a certain number of cycles the code will clear and the light will go off all by itself. Odds are the morons at AutoZone wouldn't damage anything, but you never know.

Take care and enjoy the ride,

I got a new whole MAF unit for pretty cheap ($185) at autohausaz.com and all I had to do was swap the old unit out (5 minutes). I'm not sure that buying the insert only is worth the hassle it sounds like it takes to install.

Hassle? It's two screws. In your case, the savings amount to $23 per screw.

counting 20 seconds per screw I think I can beat most of this country lawyers in income
Actually took me longer to remove clamps and pull the MAF tube, that was jammed between covers, than just take screws out and swap the insert.
