**SOLVED *8
Hi
Newbie to the forum, and I know this is an old thread, but I’ve had the same issue aa original poster and did a diy fix that thought useful to share.
Firstly, in this thread there are *two* different issues being discussed, so let’s clear that up first.
The first issue is the ratchet system. That’s the thing responsible for “locking” the arm rest in place, which you can do if you lift it slowly from the lowest position and then (as the ratchet engages on the first tooth), press down and it’ll not budge downwards (if ratchet is working). You can move it upwards (to higher ratchet position) or all the all the way to vertical.
If you’re unable to get it to lock and it always ends up at the bottom position, ratchet mech is probably at fault.
The second issue (and Chard’s issue described in start of this thread) is about there being a little resistance as the armrest moves (similar to a door that has a soft closing motion). I’ve seen several people complain about lack of any resistance at all. It is this resistance that allows the armrest to stay in vertical position without having to hold it there, and also allows the arm to glide down to bottom position if you push it, rather than slam.
And it’s that second issue (no resistance in the movement) that I solved on my 2018 SQ5 today.
(side note, car under Audi warranty in UK, but they exclude upholstery and interior trim on page 10 of warranty doc, and refused to accept they fix it when I called to argue the decision, hence my DIY attempt. And they wanted over £600 for a new armrest!)
Ok, so, the armrest pivots, and the resistance (friction) is created by two torx bolts, one either side of the armrest mount. If those (either or both) are loose, they do not apply any pressure to the pivot, and so it flops loosely. To create the required friction to make it move slowly and smoothly, those bolts have to be tightened up. (you can’t keep tightening them until movement stops completely, the max torque create the correct amount of friction)
I found mine were loose.
To tighten them, I had to remove the rear part of the armrest (the part where the rear passenger vents are, and the rear climate control is), and then, could just about get a torx bit in to tighten the bolts on both sides (after removing two small white circle stickers that cover the torx head - no idea what those are there for) Ideally, you’d have to remove the side trim from the armrest to get access to the two side bolts, but honestly just getting the rear trim removed was enough of a challenge to put me off that.
I’m pretty sure that all those of you with “floppy” armrests (that still engage in the ratchet), have just got loose pivot bolts that have come loose with time and the up/down movements.
If anyone out there wants to k ow more, reply to this post, or message me, and I’ll try and provide more info, pictures. It’s a relatively easy fix once you get over the trauma of removing the rear bit of trim that feels likes it’s never coming off (it does, eventually!)
Shame on Audi UK for excluding this from a warranty fix, esp as it’s avoidable with a small blob of thread lock at build. But on the plus side, very satisfying to DIY fix and learn something.
