Hello fellow Qashqai owners

I have a question regarding my J11 1.2 Tekna 2013.

My car has been in for replacement of the timing chain, this was arround august last year, today my engine light turned yellow. The OBD code was P0594, Ive searched the forum for this code but without luck. I also have had unsolved problems with the cruise control and if I google the OBD code i get this result: https://www.obd-codes.com/p0594

How is this connected? My CC can be activated but not set to desired speed. Also my "outside" temperature shows to high values, just by a couple of Celsius, but still wrong.

Regards from Sweden.

edit: Changed to OBD:)

Unfortunately we do not have system/service documents for that engine so the DTC you report cannot be identified specifically. Your link refers to generic results which would vary across vehicles and engines. If the car is running correctly its probably a problem with CC inputs (switches) to the AUTOMATIC SPEED CONTROL DEVICE (ASCD) like brake or clutch?

Temperature sensing would be something else I suspect?

Thanks for the fast respons, I have checked the connectors for the brake lights and clutch, no error there.

P0594 is a generic error from what I've seen relating to the CC being disabled, probably as a result of another issue. Had it with my Thermostat coolant temperature sensor failure previously.
