How many km / miles since your last oil change? Have you checked the oil level?

How many km / miles are on the vehicle?

Do you have a Windows mobile computer -- laptop, notebook, netbook, tablet ?

Your Winnebago must get a lot of attention in Norway.

HPOP is High Pressure Oil Pump. It uses engine oil to create high pressure in the injectors to fire the fuel through them. This is why I asked about the age of the oil. When oil gets old and breaks down, and then gets hot, it is more difficult to produce the very high oil pressures required to efficiently run the engine. This is why it's important to change your oil regularly (in km, I would say every 5000 to 8000 km), and to keep the level up to normal.

A "generic" or standard OBD-II device will not properly communicate with our generation of Powerstroke (we call them "OBS" for "old body style"). That message about 121 codes is probably a "false alarm". Our generation of truck uses a communication protocol that is not standard OBD-II.

There is an inexpensive alternative. I don't know about shipping to Europe, but look for a device like this -
Amazon Amazon
. With this combination, you can scan for codes (REAL codes), perform a few diagnostic tests, and even read real-time sensor data.

I haven't had a problem with the turbo o-ring seal, but I have heard that it can leak. Are you seeing engine oil in the valley (that's the "V" part of the engine) under the turbo? Look closely and make SURE that it's oil. The fuel filter and fuel pump can also leak diesel fuel into the valley.

Hi and thanks. I understand and think HPOP was that you write. Amazon dont send/ skip to Norway are standing in homeside. But I will try to google the cable.
Its oil in the valley ,not diesel and therefor I think there was used 3 l oil in our tour in summer. (full oilpan is 12 l ) only for 3 weeks and this " broken" O ring,.
I will try to change this first. I have to take off turbo to do this, ( very little place for my big hands ,in valley) I will thank you for very good help,madpogue. In Norway the mecanichs never heard about this problem before : I am first ??? I dont think. Do you know where I can buy an ekstra "brain" /box for my Ford. I have change 2 for 6 years,before the brain was on left side/motor room and get water on,before I fiks it.A brain/box cost about 2250 us dollar in Norway. Best regards Trygve lauritsen (also on facebook)

Injection pressure regulator valve (IPR valve). I had this issue last year. Would start fine when cold but when hot it wouldn't start until I let it sit for an hour. A few times it shut off while I was driving. You can rebuild this kit however that didn't work for me as the issue was in the electrical portion of the valve. I ended up replacing IPR valve and have been trouble free since.

IPR=injector pressure regulator. If you are going to pull it to change the O ring defiantly change out the little O rings on the IPR, they are cheap. Be really clean, dirt and IPR don't mix.
