Cruise control not working

It either fixes them, or they get replaced, so as noted, no loss either way..

I suppose I could develop carpel tunnel however if I cycle the switches too much...

Would be very interested to see how you get the stalk apart, as I haven't been brave enough to try yet...

Me too, does anyone know how to replace or dismantle it?

Mine has started seriously playing up again. The other day it did work eventually after some "abuse" of the switches, but yesterday it just wasn't playing at all.

Also, does anyone know if there are any codes that might show up as a fault.

Mine is the PF version, so you do indeed feel the earth move (under the accelerator).

I'd suggest squirting some switch cleaner/ lubricant around/ into the offending areas then vigourously working the switches.....
Be careful not to spray all over the interior though, so hold a cloth/ rag around the stalk...

Well, as noted briefly in another thread, I've doused it in Isopropanol several times and worked the switches "vigorously". Nothing mucky came out though.
Been on a short slow test drive - about 20 minutes at 30/40mph - and it still wasn't working despite trying every few yards.

Then just short of home it suddenly engaged; I have no idea what was different. Just enough time to check that the increase speed switch worked before having to brake and turn off down my road.
(no opportunity to continue and test further due to roadworks with traffic lights)

So, none the wiser really.

However, looking closely at the switch it appears that it "might" be possible to prise it open in situ without taking the stalk off (airbag out job methinks ) - anyone ever tried that or know if it's possible?

I had problems when I got my S8 in January. The issues boiled down to 2. Firstly, underuse made the switch temperamental and, secondly, my right foot. If I left my foot on the throttle for a nanosecond after pressing the CC engage switch it would not engage. The trick was to ensure you lifted your foot off in the nanosecond before you engaged.

The removal route is well covered in Audi pages (as you probably know):

Ah, thanks for that useful "how to" link.
Mine's a late 98 so I do need to check the revision carefully!

As for "foot off first" I do that automatically, but I have found in the past that it wasn't strictly necessary.

Is there any way to tell, without dismantling, whether you have a RevC or RevN cruise stalk?
Looking at the AudiPages photo the cloth-wrapped cable seems to leave the back of the stalk in a different direction...
Down, forwards, up and across on C.
Up, forwards, down and across on N.

Edit: I can see mine leaves the back of the stalk, goes up, round a plastic lug and towards the driver, then down the drivers face of the stalk back and across into the cowling.
So, I guess it's an "N".......
