Possible DEF Head Failure
Please forgive me if this is posted elsewhere, I did a search but was unable to find a relevant thread. We have a 2020 Newmar 4369 Dutch Star. We just returned from a short trip within the state we live in, Florida. Upon moving the coach this past weekend to wash it (love bugs splattered on the front end) I noticed a "check engine" light and "LOW DEF" indicator light. However, DEF is at 40%, so not low. I fear we may have the dreaded DEF head failure. I've read that it is possible to clear the warning by disconnecting the DEF head, waiting a few minutes and plug it back in. Also read that using a code reader can do a similar clearing of the errors, however the socket under the dash is NOT the typical OBDII, it is a round socket receptacle which is simply labeled "OBD". I'm pretty sure getting a replacement DEF head (Gen 7) could take many months, in which case our RV is grounded for a while. Any advice? Thank you.
