Renault Master Cruise Control Failure

I had something similar on my Master. Check the throttle position sensor and the connection to the clock spring. Also, have you checked for blown fuses?

Thanks! Where's the throttle position sensor located? And is the clock spring easy to get to, or do I need special tools?

Without seeing it, I can't say exactly, but you'll probably need specific tools. If you have a code reader, check the speed sensor output. Honestly, I'd take it to a workshop before you start taking things apart yourself. You'll probably need a professional diagnostic anyway.

Thanks a lot! I took it to a workshop, and you were right – it was a defective cable connection, like the error memory said. Cost 95€ to fix. Appreciate your help!
