Vaccum style, what usually goes bad on those units? Switch is functioning, it's got to be the actuator or the computer.



Any ideas? I scrapped it on my AE, but would like to have everything correct on the vert.

cruise control is for pussies!

i have no idea, ive never had to fix the cruise control. id imagine its the thing under the hood.



the boxes are different between na the turbo

I never got to mess with one. Wiring was ate through on mine so i ripped it out.

check the fsm. does the indicator actually say "cruise" after setting it?

Yes it does

vaccum style? wtf? I thought they all measured off the speedometer. Maybe it's different for S4 cars.



I for one like the cruise control. I can set 120 kph... use the safc and my techedge wideband and run her at 15.5 : 1 AFR to max fuel mileage.

Well it runs off the speedo, but the vacuum is used to make the adjustments. if that makes sense.



They are definetely different computers for na and t2.



It's strange, I don't really use it, but I want this car to be pretty strait up.

im pretty sure there is a pretty good section in the fsm for the cruise

I'm just pretty

I suppose we'll have to have a thong pose-off between you and 94t.

No thanks.



We should have a wet tshirt contest at the retreat though.

then it would just turn into a big sausage party

NA = vacuum servo.

Turbo = electric servo (so it can work under boost).



They rarely give trouble.

The most likely problem areas are the clutch & brake switches.

The diagnostic procedures are in the FSM.

I was thinking though, if the clutch and brake switches are bad, unless they are registering as permemently closed, it would effect the cruise. I'll have to take a look at them.

In my sig is a link to the on-line manuals.

Download the "body electrical" section & print what you need.

The S5 cruise control information starts on page 69.



The CC has it's own diagnostic system & can blink error codes.

yea who needs cruise control https://www.nopistons.com/forums/pub...1047683561.gif i took mine out and put a bar /f gauge in https://www.nopistons.com/forums/pub...1047683827.gif
