MAF assembly - how to undo the flexy connectors

[ALFAitalia]

Probably.......heat and a blade usually get them moving though.

I must admit I thought you would just be buying the sensor itself....just the bit the plug goes onto (similar to google generic pic below).....that's what I have used in the past....they are cheaper like that as they are used on lots of different cars whereas that plastic moulding will only be use on a few. Good job either way.

I would end up snapping it, its like its molded into the plastic. Maybe cutting it with a Dremel would work.
How would you find the exact correct sensor for the om642 ? Does it have a part number?

I have managed to remove the maf unit from the intake, it was a pain but i got it off in the end. I hope its easy pushing new one in.

Any pictures of your handy work. ? Have you sourced the mafs separately?
I believe these mafs are plastic welded to the batwing at the factory.

I have uploaded it on YouTube for everyone. Hope it makes sense.

Now my problem is i realised the sensor i fitted is a 5pin..much more available and cheaper than the older 4pin. Despite the car being a 2015 adblue. Ive not ordered 5 pin plug connectors convert to a 5 pin MAF.attached a wiring diagram for you guys out there.
On the left of the picture it shows left and right sensors for cars pre-2014 and the R side diagram is for 2014+. Only terminal 3 is additional which doesnt need to be connected according to one source.

Do you have the part number for just the sensor itself(not in the housing?
