Wingroad cruise control malfunction

Sounds familiar. I had a similar issue with my old Opel Astra. Cruise control packed in, threw up an error code. Have you checked the simple stuff, like the fuse box? Car electronics can be a nightmare. Could be a dodgy connection somewhere.

Fuse box, okay. Anything specific I should be looking for there? Or is it more likely to be some cable or plug issue with the cruise control itself?

Well, in my Astra, it turned out to be a corroded connector. But honestly, without proper diagnostics, you're just guessing. If you're not comfortable probing around with a multimeter, I'd advise taking it to a workshop. Save yourself a headache.

Thanks, appreciate the advice. Took it to the workshop, you were right about the defective connection. They quoted 95€ to fix it, which I've approved.
