Also, there are other frequent causes of DPF failure on 08-10 trucks, notably exhaust brake adjustment (super, super important), Intake throttle valve sticking shut (often a contributing factor), engines very overfilled with oil (which ends up in the intake and then the DPF), clogged nasty air...

6.6 is within the realm of normal. 8-9 is a new injector. Failure is indicated by frequent dips under 5, or a constant 25rpm speed delta (computer is controlling at 1500, but actual rpm ranges beyond ~1488- ~1512. Give or take. 2005-2010 trucks actually use an entirely different test to...

The burner event log will be in bcu-->view. I think. PM amount will be in ecu-->configuration-->?? There should be some sub-menus. I think. This is hard! The rental car flag is under ecu-->customization.

I guess the next questions are: Where do you live, and what year is the Sprinter?

Ok. The U-codes can generally be disregarded if the truck appears to run correctly. Except U0073, but you don't have that one, so moving on. P2002 is the general Regeneration Malfunction code. It does not point to a single sensor or item, there is a number of things that must be inspected...

U2 actuator translated into English is 'devices powered by the ecu'. Pretty much, anyway. This includes the VNT controller on the turbo, the EGR valve(s), the mass airflow sensor, and maybe some other stuff (I'd need to look at a wiring diagram).

In subzero weather, the DEF will freeze and it takes a little while for it to thaw back out. During this time, DEF injection is suspended. With conservative driving comes a lower demand for power, which results in higher EGR usage. EGR is used less when there is a large demand for power. At...

You would need everything, catalytic converters, evaporative emissions system, etc. Federally speaking, this is required. Your state may not have a means (or desire) to enforce federal emission requirements.

Crap, I'm the first person to vote. I guess I should have read the whole post first. I did an engine swap on a sprinter once, and it was a giant pain in the ass. What you are suggesting is probably not emissions legal, but I like GM's LS engines, so two thumbs up.

I like when I hear about people buying Hino DX. You can now experience the same trial-by-fire as me! HAHAHAHAHAHA!!!!! I've been using DXII for about 18 months now, and the details of DX are already getting fuzzy, but bear with me. North America: 600 series is all conventional trucks from...

Hino tow trucks tend to suffer the most regen problems. Make sure that it's ecu software is the latest version, and that the exhaust brake is adjusted correctly. While they are in there, under the engine customization menu, there is an item labeled 'Flag for rental car' or something nutty like...

I'm a fan of cotton/polyester blends.

Stop looking at my profile.

What are you trying to solve?

Let me take a step back. What is the truck used for? It suffers from overheating and frequent regens. Anything else? Is the check engine light on? Is there soot in the tailpipe? Does it run like crap for a few seconds when it's cold, then acts normal? When it's doing an automatic regen...

Fan clutch, thermostats? High idle all day...what are you doing with it? Is the exhaust brake on the whole time? Is the exhaust brake set correctly?

The next challenge is to keep it going until you retire

When you find the answer, please give us an update.

I can't think of a single case of an egr cooler clogging on one of these (where I work, anyway).

Also, what's the oil temperature when this occurs? If it's high, there may be a flow problem through the oil cooler, assuming that it has an oil thermostat. Edit: It appears that the pressures you are seeing are normal. If you felt a loss of power, it was probably unrelated. You'd have to have...
