We picked up an 07' model Komatsu 325 off-highway truck. It keeps popping up E03 code with the buzzer. The codes we've pulled from it were a low coolant and EGR. Coolant is fine so my question being whats the EGR fix? It mostly trips when cold. I'm def not a mechanic so please excuse me if I sound uneducated on this.
Any ideas or explanation will be appreciated. Thanks guys.
