Changing 1.8T DBW Idle Speed...

So I came across directions for using ECU adaptation to change your car's idle speed. This would come in handy for those of us with stiffer engine mounts and bushings, as a higher idle speed will make the car idle a little smoother.

Using a VAG-COM or ProDiag Palm Pilot, adapt channel 01 (02 in a diesel) to a value between 124 and 132.


I copied this off of another site. Does this how-to make sense? Winston and I tried to raise mine but couldn't figure it out. Anybody with a VAG COM feel confident about this one and can help me out?

I'd like to upgrade my side engine mounts at some point and I'm thinking that with the idle at stock my whole car will be constantly shuddering. *ick*

Anybody think VW will notice the raised idle speed and be cross with me? ;)

I think I've seen that screen while vagging my S4 but I never changed the values. The info you posted is also posted on Ross Tech:

http://www.ross-tech.com/vag-com/cars/18T.html

I can't imagine that a VW tech would notice that the idle adaptation numbers have been changed unless they are looking for it. But, you never know. You could always set it back to stock before taking it in.

Like others have mentioned per ross-tech:

01 for "engine" electronics
10 for "adaptation"
01 for channel 1

Per the Bentley, 128 = 860 rpm and each number should go up/down 10 rpm accordingly. So you can't get that number to change and save at all or no matter what the number is (124-132) the idle is the same?

I didn't put in the "doughnut" one. I'm just going to leave it out for now.

I'm just a little tired of the shaking steering wheel at idle/stoplights mostly. I'm pleased with the feel and now that I have the icky all-seasons back on, there is a noticeable difference in wheel hop while taking off quickly -i.e. Instead of hop, it just spins them in first, most of second and into third -but it does it smoothly!

I forgot I had just put them on the other day and took off from a light next to a friend of mine who was fooling around and spun them pretty much all the way through the intersection.
Bad Andrew...  ;)

Okay, thanks Andrew, cool but I'm not familiar with the VAG software enough to know what this means. :?

I know how you feel, the other day I poped the clutch a little hard going into second. snow tires are way to soft and I feel bad when ever they spin. just eats em up.

My new bushings were really stiff for a while but they have gotten alot softer. but when its less than about 30 degrees they are still pretty rough.

Select control module:



Select engine (01):



Select adaptation (10):



Select channel 1 (01) and type in your desired idle:

Hehe, I got to thinking that probably wasn't in the best of taste. Did you end up calling Alan?

Nope, I knew it was you guys after I called you.  I had this flapping piece of paper stuck to my windsheild all the way home, and lucky for Alan I read it AFTER I called you, that would have been bad... Funny though... :)

Well, currently I am taking time "off" which translates to kinda working when you work for yourself... so whenever.  I have a meeting with a new client downtown next week, but I can meet up with you anytime in the next couple days... maybe lunch tomorrow?
