320 v6 CDI air sensor

[ldare]

hi
I have a 2007 W251 R320 which i think is the same really as an ML320 and GL320 under the hood.

It started to feel quite lumpy and the exhaust quite dirty so had a good look over the air intake and pipes.

I noticed a sensor and it's pipe wasnt wasn't sat right and lots of mosture...bingo.

However Im not sure if it is going to pop out again? It just pushes in with a red gasket, doesnt seem to be a clip? Should there be? Should it be held tight or just pushed in?

Hopefully my photos identify what I have pushed back in.

Thanks

The area is always oily. The red rubber bit does have a tendency to walk out again unless it is scrupulously dried of oil residue and its hole in the hard plastic cleaned and dried too. The bit that pushes into the middle of the red rubber seal is barbed, and a bit of oil helps that push in, and that part won't walk out again.

Yip just a push fit tail so needs to be cleaned off thoroughly

All cleaned up. Does it matter what order they go back? Ie rubber on sensor and push in the hole or put the rubber in the hole and push the sensor in?

Cheers

Doesn’t matter really

I always put the rubber in the hole first. It has a little notch and cutout to align.

Hi
