Mine showed up as an error on the scanner too. Called a regular stokists, none of them sold this item before. Decided to go shopping at shop chop and found a used unit. Replaced it and error's gone.

On another note, if you're always on Internal Circulation, then the AUC is redundant to be replaced.

Just sharing what i know

Btw, the location for the sensor on M52 and M54 is different. M52 is just below the top radiator hose. M54 is located in the lower right corner of the fan shroud as shown in the 1st pic.

The error is detected on my S62, but I guess it should be somewhere around the same area as M52 or M54.
