Where did you hear that? I've been using CRC every year, since my original MAF died, that was back in ~2006, I now have 134K on the car and probably 70K on this MAF.Yes it can be. I'm considering doing this myself but I've heard it only shortens the life of the MAF.
Nah, that is not what people say. What they say is that cleaning it doesn't seem to extend the life very much. It can be done, but when it is going it will still go even if you clean it. Most threads on cleaning MAF involve people with MAFs that are going already, so it just seems like cleaning it is causing it since their MAFs die like 10K laterYes it can be. I'm considering doing this myself but I've heard it only shortens the life of the MAF.
According to my Bentley manual (page 130-9):what are the symptoms of maf failure?
A faulty MAF sensor can produce the following problems:
- Difficult to restart when engine is hot
- Engine starts then stalls
- Engine starts and runs only with accelerator pedal depressed,
I cleaned mine a month ago or so and do recommend it.Can MAF be cleaned with CRC MAF sensor cleaner? If so, is it recommended at all?
OP doesn't have an ICV as he has a VANOS E39 (99-03)I cleaned mine a month ago or so and do recommend it.
Blubee, does the Idle Control Valve (ICV) also play a role in the symptoms the OP has described? If so may consider cleaning it as well. The MAF is much simpler to get to so I'd start there.

Clean Your MAF - Its so simple even I did it today!
+1NO idle control valve on Vanos E39s? I just looked up the PN for one at my work and for my 2001 3.0 lists a 13 41 1 744 713 as the part number for it...
Search Ebay with the Bosch part number. There is a Bosch dealer that sells new, original Bosch MAFs at great prices...better than anywhere online. I got mine there. Watch out though, there are lots of sellers with no name or generics for sale. The guy with the original Bosch ones is very upfront in his listings what you are getting.I am planning on replacing MAF.
