Is there a fuse in the side dash panel or under the hood that might need replacing? My cruise control doesn't even come on. Need help please!!!!!! Going on a long road trip pretty soon!!!!

fuse #31 is for cruise control,tail lights,and auto transmission.

if its not the fuse use some electrical cleaner on the switch, worked for me!!!

I had to have the module rebuilt on mine. Contact www.autoecu.com They rebuilt mine for about $60+shipping & offered a 2 year guarantee.

Thanks guys for your help....I'll check it out.........But if it is the module....where is it located and what does it look like?

i think this is what he is talking about. but not sure. ecs sells them new for 130.

I have this same problem, my friend who is an audi tech suggested that it was either the switch which is in the picture ^^^^ or it is the cruise control module. we tested the switch and it passed, but the module failed. we removed it from behind the glove box and i still havent had it rebuilt. but that module failed continueously. try getting some wiring diagrams and test the module, it may need to be rebuilt.

sorry i forgot to add...... the module looks like a 1" x 2" x 4" aluminum box with the a part number 5GA 004 397-16, it has a 12 pin connector, and again it is behind your glove box, up under your dash

Sandman,
I'm a rookie to audis........do i have to take my steering column apart to
disassemble the cruise control switch, so I could spray it with electrical
cleaner? Please walk me through.....I live in Vancouver, WA., and going to be
driving to SoCal soon. Cruise control would be beautiful!
Thanks,
Goddzilla

Just spray the switch where it is. Then move the switch. Hold a paper towel behind where you spray.
