Bought a PM 3500 diesel on Jan 13, Throttle warning lite and ck engine came on in first 20 miles. Now in the shop awaiting a new EGR, which I read here, don't even exist. Will be going to dealer tomorrow for a C2J meeting. Can't have a vehicle I can't depend on. I also cannot keep driving during Regen, If I am pulling into a customer's drive when the light comes on. Love the truck, think they have a lot to do to make the diesel a usable option. Mainly have spare parts available BEFORE they release a truck for sale.
