Re: 01 audi tt quattro cruise controle stopped working
You own an Audi, everything is expensive. If your cruise light doesn't come on at all, you have an electrical problem. If the light comes on, you have an actuator problem, or a vacuum problem. The dealer, or a shop that works on Audi's should be able to find the problem.

cruise control have there own fuse check that ,make sure it is still hooked up to throttle ,check vacuum lines and power plugs , your speedo has nothing to do with cruise,also check that it is activated,test horn ,YES horn and cruise use same relay ,make sure your brake pedal is retracted ,and that brake lights work as well, good luck with it if I can be of further help get back to me ,hope I helped you.
Could be the problem; however it is more likely to be under the hood where the cruise actuator is located - check the electrical connections on the actuator and the linkage between the actuator and the accelerator lever on the engine. Also, if the cruise control uses a diaphragm to control the accelerator, it may be leaking or the vacuum line to it may have fallen off - check the vacuum at the actuator with the engine running.
Your dealership should have seen any underlying codes. Most Cruise controls I've worked on are used on the vehicles vacuum. that is where i would start, because on a grade your engine uses more vacuum pressure thus taking from some where else.
CRUISE CONTROL PROBLEMS CAN BE CAUSED BY FUSE OR FAULTY BRAKE LIGHT SWITCH OR BLOWED FUSE TO BRAKE SWITCH.YOUR CRUISE CONTROL SWITCH COULD BE FAULTY.BEST TO TAKE CAR TO DEALERSHIP LET THEM HOOK CAR. TO DIAGNOSTIC EQUIPMENT.BECAUSE CRUISE CONTROL IS ELECTRONIC AND PCM CONTROL.THE CRUISE CONTROL SYSTEM USES INPUTS FROM VSS SENSOR .SO IT WOULD BE HARD TO FIX AT HOME YOU NEED EQUIPMENT TO FIX AND TROUBLE SHOOT.
cruise control operation is reliant on the following
road speed sensor ( speedo or VSS sensor )
engine rpms tacho/ ignition coil/module problem
clutch pedal sensor (VSS in automatic )
gear selection position sensor ( not properly adjusted causing flickering of the selector light)
brake pedal sensor
bad ground wire connections
r all need to work together or the CC will stop working
nothing to do with vents and all that you mentioned.
wire connections and harness connections for the transmission are suspect
CC will not operate under certain engine rpms and road speed
