Hi, my name is Spikes and I am joining from Denmark. I am driving a 2011 D40 3.5 ton Diesel with a camper cabin. I had from the get go a problem with the Fault Code P0380. About once a month the yellow engine light comes on. I got so sick of making appointments at the dealers that after 2 years I bought a code reader and just deleted the code myself instead of paying 15,00 bucks every time. I heard every excuse from glow plugs to parking at a bank parking lot sending a strong signal. Warranty is up now and the problem still exists. Sometimes I can drive for weeks and sometimes the light comes on several times a day when starting the engine. Does anyone have a similar experience? I appreciate any idea on how to fix this problem.
