Door hinges

[Paulprior]

My wife’s Audi passenger door is slow to close, no creaking but it needs a firm push to close it, what is recommended to lubricate it and where ?, I assume WD40 is not the answer

Historically I've used Fluid Film, but have just bought some WD40 white lithium grease.

Lithium grease is what I would use. Also useful on your window hinges in the house , caravan etc.

Lithium grease it is then, how do you get it into the hinge rather than just on it ?

Same way you would get standard wd40 into the hinge.

A squirt of engine oil will work fine

I use a little 3 in 1 oil in aerosol form, never really got the spray grease thing.

The spray can has a straw attachment.

does the door stay open on the "notches" on an incline or whatever or is it free to move?

If not It'll be the check link arm failing.

The arm is usually a forged core with an overmould with dimples in it. The arm itself will be attached to the slam area between the hinges. In the door there's a little block that essentially contains two sprung plungers that pinch the arm. As the dimples go past the sprung plungers it holds the door in the desired positions and it stays there until moved.

Usually there are three positions.

If the door is slow and or hard to close then either the ploastic over mould has worn away and binding bit or the sprung pins have worn flat and not gliding. Try a smear of grease on the arm that goes in and out of the door.

(There are a few systems that are "any position hold" but they're very expensive and I don't think they've made it onto any Audi's yet but I maybe mistaken, possibly a Q7, A8 or etron)
