I've a 2005 320 cdi w/195k miles on it. According to the code read done at Advance Auto Parts my cel and limp mode is caused by a defective MAF.

Before ordering the part I attempted to clean the contacts on the two plugs on the unit. Small plug came out well. The larger connector was accessed after removing the plastic (cosmetic) cam cover.

Exactly how do I release the connector with the plastic tabs on each end? Do I pry out or push in before pulling the connector out?

Are there any other porblems I might encounter doing an r and r on the MAF? Does it harm the car to drive hours in limp mode?

Locations fora best price on the unit? Seems as though it's unavailable here as well as at most parts suppliers. I want to stay with a MB part only.

Thanks!

You might try posting on the diesel forum. (this is a diesel right?...) I don't think regular MAF's have two connectors on them. But as a general rule, connectors like that always have some kind of locking latches on them. Some you push, some you pry. Maybe post a picture of it if you can. Good luck.
