NHTSA Complaint #11425251 — 2019 ENTEGRA ASPIRE

Diesel Exhaust Fluid (DEF) head failure. Diagnostics codes SPN 3364 / 1761 / 3031 The offending unit is not available from me, the mobile mechanic took it with him. My Motorcoach derated. I was able to get to a safe parking spot, where I waited one week to be repaired, (1000 miles from home) Could not move from that spot, as top speed was limited to 5 MPH. I was warned during travel by dashboard warning lights to check engine. It was good I was aware of potential DEF head issues, so I immediately checked the diagnostic codes, then immediately found a safe place to stop. I contacted Spartan, Entegra, and Coachnet, whom between them, acknowledged the problem and sent a replacement head. Once the head was replaced, fault codes were cleared and I was able to continue. So, other than the monitoring head itself being faulty, all the inputs the head monitored were fine.
