Peugeot 807 Cruise Control Failure

My 2009 Peugeot 807 diesel's cruise control has stopped working at 169641 km. The dashboard light doesn't illuminate, and the speed won't lock. Fuses are fine, but I'm getting an error. I suspect a cable or plug connection issue. Any ideas where to start?

A 2009 Peugeot 807 diesel experienced cruise control failure at 169641 km, with the dashboard light not illuminating and the speed not locking. The issue was suspected to be a cable or plug connection problem, as fuses were fine but an error was present. After taking the vehicle to a workshop, it was confirmed to be a defective cable or plug connection, which was repaired, restoring the cruise control functionality.

I had a similar cruise control problem with my 807. Did you check the connection to the speed sensor? Also, a faulty steering wheel control module can cause this. Is the dashboard light working?

Where exactly is the speed sensor located? Is there any way to test the steering wheel control module before replacing parts? Or is that a garage job?

The speed sensor is typically near the gearbox, but confirm with a repair manual for your engine type. Testing the steering wheel control module requires diagnostic equipment. If you're getting an error code related to it, and the cruise control is definitely the problem, I'd recommend professional help to avoid further issues.

Took it to the workshop. It was a defective cable or plug connection. Cost 95€ but cruise control is back.
