I had a breakdown this year along I70. I had to call for service using the Newmar Club service. The vendor they sent was able to assist in getting the unit started and I drove it to the nearest truck stop. The truck stop replaced the fuel filter, but this didn't resolve the problem. They checked the computer code, which was a 164-2. They stopped at that point, as the vehicle is still under warranty, they were not authorized to work on Cat engine. We set there for two days waiting for the Cat parts store and service center to open. The local cat dealer determined that the problem was associated with a sensor telling the computer that the engine was having erratic oil pressure, causing the computer to shut the engine down. Sensor was replaced and problem appears to have been resolved.
