2016 Octavia Mk3. Intermittent cruise control issue. I love cruise control! When it does work (having randomly flicked the stalk switch to check if it is in the mood), it stays on for 2 or 3 minutes, disengages and then the orange light comes on. I've been told it is a unit replacement (€350 -€450!). Ive tried cleaning inside the stalk. Woked for a bit but...... Any suggestions before I replace the unit?

You almost certainly have a broken wire in the steering column unit. Disassemble and inspect the wiring.

Might be worth getting it scanned as well. It could be a failing brake switch or if fitted dirty front radar sensor.
