Eberspecher D5LC wouldn't start

[benktnp]

Hi

I have a D5LC 2002 mod, that has worked for many years, with no problems, suddenly it wouldn't start.I delivered it to our local Vendor for diagnose. They said that it was the overheating sensor that was gone. I Changed it with a new one, without result. Since it was difficult to get parts for it, I bought a used one from a friend of mine, same type and model, that was overhauled. After mounting it start and the diesel pump was ticking but it wouldn't ignite. I thought the diesel had not reached the burner and restarted it five times, then it died. and was totally dead after that. Is there a way to reset it? Can anyone help me?

Do you have the manuals?

It could be a number of things. I am no expert, but I had similar symptoms to you and it turned out to be low voltage during starting. They draw a few amps to start and will abort on low voltage. Ensure your batteries and the wiring to the heater are both up to the task.

There are generic copies of the espar and webasto heaters available for very cheap if you decide to replace.

My first advice would be to get the espar code reader. They aren’t cheap, but they are well worth being able to diagnose issues with your heater. I’m glad we bought one.

Problem I encounter most in situations such as yours it's the glow plug screen that is Carbone's up badly and not allowing atomized fuel to reach the glow plug for ignition.
