Keeping them clean can prolong the life, but once you get past a certain point, no amount of cleaning will help.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Sure this has been asked before but cannot locate it or on the Tech Tips page. How easy is it to clean the MAF, pitfalls, cleaning fluid to use, etc. Thanks

POST 3Original post

You can see the MAF at the outlet to the air filter housing, near the rubber hose to the throttle body. It is held on by two T20 security Torx screws. You can get a T20 security bit in any decent tool shop, or Halfords, etc. It is easiest to undo the screws and remove the MAF before disconnecting it from the plug. I use IPA (that's isopropyl alcohol, not India Pale Ale). Give it a good soaking in the cross-slots and the hole in the bottom. I'll post some photos when I get to my PC tomorrow.

POST 4Original post

Just remembered the pics........ This is on my Turbo, but you'll get the idea.

POST 5Original post

The best product to use is Electronic Solvent Cleaner - available from Maplins: http://www.maplin.co.uk/electronic-solvent-cleaner-30056 It doesn't leave a residue behind unlike brake, carb cleaner, thinners etc.

POST 6Original post

By the way DO NOT in any circumstances touch the sensor itself. Only use the spray cleaner.

POST 7 / ORIGINAL POSTEROriginal post

Very many thanks for all the replies and tips and also for the pictures Richard.

POST 8Original post

Although they have a quoted life of over 100,000 miles, many become a problem at around half that distance. Keeping them clean can prolong the life, but once you get past a certain point, no amount of cleaning will help. If your car had a new MAF with the new engine (it would have been if it was a Porsche exchange engine) then I wouldn't worry too much.

This is a source reference. Confirm exact model applicability in the original material.
