Air Flow Meter

[cinquecento]

The bolt that secures the air flow meter to the body is turning freely... seems the nut that's hidden inside the body panel has either broken away from it's bonding.. or is stripped.

How does one get into that area... can't see any way throught the engine bay or even via the wheel arch??

thanks..

From memory, I think it's a self tapping bolt which taps in to the body.

Yeah, I've seen them for sale at classic car show etc. I don't think there's any access from underneath, you need to extract the old one and fit a new one, or just pop a new one in next to the old one.

My 98 500 has a tapped bush fitted and uses a standard bolt. It doesn't look like a mod.

Hi Lindsay,the thredded nut does look more like a bush as its depth is greater than that of a std nut.You can access it i'd guess, by removing the inspection cover on the inside of the wing just a couple of inches further up,towards the windscreen.This cover is mostly obscured from view by the afm and the air pipe.It is held in place on mine by 1/8" rivets,but once removed,some self tappers can be used to re-fit(was on my previous griff).Dont forget to use a good sealant around the outer inside surface when re-applying,as the inner wing forms as part of your vent ducting,and youll loose perfomance on an already struggling std sytem if you have any gaps.Hope this helps,cheers,Mike

There called nut serts i think, you put them in with a kind of rivet gun.Might also be called a clinch nut kit.

After gaining access by removing the panel next to the AFM that Mike suggested, I could'nt get a solid grip onto the "nut" inside.. which isn't really a nut.. it's a round (!!!) metal cylinder (with the tread inside). This had indeed separated from the GRP body.

Ended up inserting an upside down bolt from the inside the panel, held tight by a washer and nut.. then the AFM is held tight by another nut. Need to be careful abt the height of the bolt.. otherwise it would hit the bonnet. Works just fine. Thanks to all!!

Would drop one off for you if you pay petrol for trip, priced up for a kit it was £45.
