Adaptive Cruise Control Issue

[1AX]

Only had one journey in my car so far but I attempted to use ACC which resulted in the error message "ACC not available - drivers seatbelt unfastened".

Seatbelt was obviously fastened and there were no other warnings from the car during normal driving to say it wasn't, meaning the car did know it was fastened.

Hoping this was a one-off gremlin and it will work fine on the next journey...find out tomorrow!

First two or three journeys in the car this error persisted but it has now cleared itself.

Feels likely a low charge on the 12v battery could have been the cause, as experienced by @CHP in his Macan, but more use has charged it to an acceptable level

Update! Car is home. ACC working! They did change the front camera and had to replace the EM Brake controller as they could not get the faults to clear on the original. I feel pretty good about that fix, as this has been the faults that they were not able to clear at the PDI. Happier to know that it was bad from jump, than had it failed. I am skeptical that the camera was actually bad though. Warranty, so no skin off my back.

Well, that didn’t last long! Left car for several days with my PPF guy and on pickup, the ACC is out again. This time it’s the driver’s seatbelt glitch. I guess we’ll give it a few days and see if it clears as it has for some others. Leaving it parked until my ceramic guy gets it finished next week.
