Viano cruise control issue

Whoa, that sounds familiar! I had almost the exact same problem with my Vito. Cruise control just quit, and it turned out to be a dodgy connection. You mentioned fuses, good start! Did you actually test them with a multimeter or just visually inspect them? Sometimes they can look fine but are actually broken. Also, and this is important, check the wiring around the brake light switch REALLY carefully. A short there can mess with the whole system because the cruise control disengages when you hit the brakes. The clock spring is also a good shout, but those usually affect more things than just cruise control, like the horn or airbag. Just throwing out ideas, you know?

Thanks for the quick reply. Yes, I did test the fuses with a multimeter, all okay there. The wiring around the brake light switch looked okay on visual inspection, but I'll definitely give it a closer look. You mentioned 'dodgy connection' was it something obvious once you found it, or did it take a lot of searching? And did you mean the brake light switch connection specifically? I'm just trying to narrow down the search area before I start dismantling half the dashboard.

Yeah, 'dodgy connection' is my attempt at sounding technical lol! For me, it WAS the brake light switch connector. I spent ages checking everything else first. Honestly, my advice? Book it into a workshop. I messed around with mine for ages and probably cost myself more time and stress than it was worth. They've got the proper diagnostic tools and know where to look. That way you don't end up chasing ghosts and potentially breaking something else in the process. Save yourself the headache!

Appreciate the advice. I took your suggestion and booked it into a local garage. Turns out it was a corroded connector on the cruise control module itself, just as you suspected. They cleaned it up and it's working perfectly again. Total cost 95€ Thanks again for your help!
