Hey all, just wondering if anyone has received this code on a GLK250.. It's a 2014 and has 73,000 miles, from my understanding this is the "reductant level circuit sensor high" error.. Something to do with the adblue tank, but I haven't seen a message to add def or any messages about limited starts.

Just looking for some ammo before I head into the shop where they'll tell me I need to replace the entire system or something ludicrous

I couldn't find anything on this forum specific to the GLK and this issue, but others have mentioned a re-calibration of the float in the tank or something to that degree with other MBs

Thank ahead of time
