Trouble Ticket Help Requests for DTC P203D
Help Request Posted
2012 Mercedes-Benz GL350 Bluetec 4Matic 3.0L MIL Lamp on VIN: 4JGBF2FE9C
P203D: Adblue fill level sensor has short circuit to positive. I have reached out to xemodex regarding warranty but have not yet heard back. I understand the issue to be either a failed wire or the fill level sensor is failed. Please advise if you have any advice. Thank you.
