The cruise control went intermittant, then quit completely.
I bought the car about 3 months ago, finding the cruise would suddenly shut off or not even connect unless I kept turning it off, then on and set, finally one day it set, went about a mile on, shut off and hasn't worked since. Is there a wire broken, a sensor malfunctioning, or a switch broken, or what?

Re: The cruise control went intermittant, then quit...
Where is the switch for your cruise control? Is it mounted on the turn signal stalk? If so, it's likely a failure of the stalk. The Audi cars of your generation are known for stalk failures (my 99 A4 has had it twice), and it's likely that VW and Audi share switchgear as they're both part of the same conglomerate parent company. If your switch is on the stalk, you're likely going to have to change it out for a new one. I'd recommend German AutoParts in Albany, NY for buying one (www.germanautoparts.com) - I've bought several parts from them in the past and they're top-notch for service and pricing.

cruise control module has failed. or if your brake lights are staying on, then brake light switch has failed and not allowing cruise to engage. Have someone stand behind truck and see if brakes are working properly, if not- replace brake light switch. if fine, then swap out cruise control module under hood.... prob find one at a junk yard.
you could have a problem with the brake switch which de-activates the cruise when you push on the brake or a bad cruise switch or control module.have the cruise system checked out to find what is causing the problem first then go from there.
Check for anything that may be against your throttle cable. Look from the throttle body and follow it to the firewall. Your throttle body (butterfly could be staying open) The throttle body may need to be cleaned, once these get gunk built up, the butterfly will not close completely. If it can't go to a close state, the it's like having your foot on the gas pedal a little. The cleaner can be purchase at a local auto store. (throttle body cleaner)
I have a 1998 GMC Safari van in which the cruise control has quit. It didn't go all at once. It would work intermittently. Sometimes going 5 miles or so and then shutting off and then after another few miles, it would set again. This sounds to me like something getting hot. Is there a circuit breaker for the cruise control...or? I can't seem to find a good schematic/diagram for the unit. Driving me nuts! I don't want to have to buy a whole new module if there is a simple fix.
Faulty product. I install cruise control for 6 years. One of the cables are hooked into the throttle and the other in the vaccuum actuator, since it is electronically controlled actuator, the object itself might be losing it's contents or frankly worded, is taking a nose dive. works much like a brake booster does.
Is it a PID system? (Proportional integral derivative system)
or is it just standard proportional?
That will play a factor.
If you just have one of those cheesy controls (cruise controls), than replace it, obviously it wouldnt of cost much. if it is not, check the actuator and replace it! Replace the Fuse, brush it with wire brush, clean up all connections.
You should be ready to roll!
here are two switches that are the usual causes of the cruise kicking
out. they are both under the dash. One is the switch for the brake
lamps (stop light switch). the other is for the clutch if you have a
if you follow the brake pedal up under the dash you'll find two
switches at the top of the pedal. (it may be one switch but I think its
two). the top one would be for the cruise control. if the switch is
loose it will cause the cruise control to think you're stepping on the
brake and that will disengage the cruise control
same with the clutch pedal if you have a manual transmission; if the
switch is loose it will indicate you are pushing the clutch pedal in
and cause the cruise to kick out
other than that you'll have to check all of the connectors. If it does
engage then the fuses and actuators should be good and it would be a
loose connector or switch that's kicking it out
also, i assume your speedometer works; if its not then that's your problem as the cruise won't engage under 30 mph
