Just raised it, thanks. I try increasing it before with VCDS but it would keep failing. Just updated VCDS and now it worked.

SOOOO Happy this is now possible!! I'll be doing this myself just because I still notice it every now and again. Hoping th ecombo of RS7 plugs and 50 rpm increase resolves this issue.

You sir are a gentleman and a scholar, this is an amazing discovery.
On obdeleven it gives you the parameters of "0-255" why do you say select 50? I appreciate you finding and sharing this. I set it to 50 and it feels better, but still recording missfires just not as many

A shift of 100 would be ideal, my car ran so much smoother with a load from the AC.
Yeah but i dont think it works like that. I dont believe it raised the idle 50 rpm as my rpm stayed just short of 800 as usual. I think its some sort of algerithim nerd stuff. That's why im asking if there is a reason 50 was selected. You could always try 100 and let us know

yea same issue here, without ac on i get a weird idle at times. Cold starts are perfect, its like at 1k but then once it warms up it drops to like 0.7k and gives me that weird idle at times. I changes plugs to rs7 and got a bit better but still there. Its the rpms for sure

Same here, tried changing spark plugs but it's almost the same.
I noticed first at 8k miles Apr stage 1, now 22k stage 2 is the same at least is not worst...

I'm not the one that figured it out. That credit goes to WOLF, he put it in one of his videos last week. In it, he says that VCDS will only allow you to do 50. I haven't tested any higher than 50 so that's why I said that number in the post.
My understanding is that this function is there to provide a quick way to adjust idle speed without changing how the engine is running/programmed. It basically just tells the ecu to add 50rpm to what the ecu thinks the idle speed should be.
I wouldn't read too much into the 0-255 part. I can tell you that that range is there because of the binary language that the ecu uses.

Sooooooooo, after reading this thread for a while I notice that the idle does seem to be a bit rough. It's so subtle though. I've noticed it after I installed the engine and transmission mounts a few weeks ago.
I've heard the idle discribed as "fish bite idle". Sounds about right. But it's not bad enough to really bother me. Compared to a diesel that I came from it's definitely smoother

50 is the highest setting possible. Simple.
