Hi All.
I know this has been discussed multiple times before on the thread, but I'm struggling to find definitive answerss.
Car - 2014 KX2 2.2 Manual. 92000Miles
Problem - AWD NOT working. Not cutting in automatically when stuck, nor when pressing the LOCK button. I know this as I keep getting stuck in a field (tow hay trailers and horses with it) It was working in November, but not since then.
Took it to a 4wd specialist as wanted an opinion before spending £££ on new coupling or KIA diagnostics.
Work done there -
P1832 Clutch Thermal Over Stress Shut Down
At stationary wheel speed are wrong - RR reading 1083mph - however reading correct when driving.
Looking at a link from kia (im not allowed to post it .....)
see below - it's posted there
Work info from KIA - would imply that it needs new coupling
However - Mechanic reports that the rear wheel turned 1/2 turn when engaging "lock" prior to codes appearing, and also no shavings in the oil - so would lead me to believer that the weld inside the coupling is intact, and the splines OK?
Speaking to My KIA garage - they say that it will need a new coupling - never come accross the Speed sensor issue before.
Likely I simply need to replace the coupling, however my thoughts lead me to believe that the erroneous reading fromthe rear speed sensor is causing the thermal shutdown - so if I could fix this then it would work?
No ABS / ESP warnings / codes, so seems the sensor is intact.
Any one any experience of this and can offer some advice / words of wisdom before I bite the bullet and replace the coupler. Its booked in with Kia early Sept to have diagnostics, but likely I'll get the work done elsewhere.
I can source a coupler for £259 so not too bad, but don't want to replace it if I don't have to and if it wont actually fix the issue:

Work done there -
- Removed and cleaned 4x4 coupling / pump / motor. Refitted and refilled wiht new oil. Said there was barely any oil left in it and what there was looked old.
- Checked earth and live were OK then tested the pump which runs wiht seperate live and earth
- Fault codes:
