...And in addition, I am going to suggest to the techs that they read this thread and maybe provide some answers to the questions posed on Regen!

Ernest,

And the type of regen Russell had to do (Manual) HAS to be done on gravel or concrete NEVER on Asphalt - the exhaust temps during regen are on the order of 1,500° F, so I would not have anything near the rear of the coach either!

Bob when they went back to the side mounted radiator they located the filters on the back. That location is higher than the tank. I can't remember if that is only for tag or all. FL told me when I inquired about it after losing 2-1/2 gals of diesel to be quick or install a shutoff in the line from the tank. But when I asked for recommendations on valve and location they said they couldn't because they don't supply one.

Wayne,
The filters in the back are only on the rear radiator XLT. I wish they had the filters located in the back on all models.

Well, looks like I am in luck!

I'll still see what the tech has to say about solutions for you guys.

Diesel particulate filters catch exhaust soot to be reduced by regeneration. From Wikipedia, DPF filters go through a regeneration process which removes this soot and lowers the filter pressure. There are three types of regeneration: active, passive, and forced. Active regeneration happens while the vehicle is not in use and takes 10 minutes on average to complete. Passive regeneration takes place while driving using the heat of the exhaust. This works well for vehicles that drive longer distances with few stops compared to those that perform short trips with many starts and stops. If the filter develops too much pressure then the last type of regeneration must be used - a forced regeneration. This involves a garage using a computer program to run the car, initiating a regeneration of the DPF manually.
They also discuss "runaway" regeneration, where regen gets too hot, causing damage.
From a little research on DEF and DPFs, I haven't found a good reason for needing a manual regen, especially after A 1200 mile run at hiway speed, the DPF should have been clean.

The reason for the manual regen was because the code could not be reset without one. I had other codes that were showing. The scanner was able to clear those. The particulate filter code was Red and said that a manual regen needed to be done then attempt to clear it.

After we did the the manual regen the scanner was able to clear it out and the coach is running fine now??

I too very much agree that just 6 mile after the coach had made a 1200 mile trip with no issues this should of not happened!! But the scanner told us what to do and that fixed it!! I'm betting I'll see it happen again. My mechanic & I feel that one sensor is probably going to need replaced.

All gauges are fine- no high temp, water level about 1" below cap. Oil pressure good. Oil full. No high temps??

I made it back home but computer will shut engine off after running maybe 3 minutes.

No one open today but I do have a friend coming to hook it to scanner to maybe read something.

Anyone had this issue.

Thanks.

I was getting multiple error codes from the DEF unit, which would de-rate the engine on the road, so had Cummins check the engine. If you have not had your engine control unit software updated to the latest version, I would suggest doing that - have not had a single error since the update.

Good info. I will see if I have another issue.

You say derated on yours?? Mine was a complete shut down. How does a derate work. I thought that where computer took some of your power away and you limp along?

And what motor do you have.?? Year & size ??

And welcome to the forum.

Hi Russell - we have a 2014 Berkshire 400QL purchased new. When the engine de-rates it feels just like turning cruise control off at speed; a sudden drop in speed and power. The ECU is reacting to an error code, and de-rating power to protect the engine. Depending on the code (or multiple codes), it can result in a complete shutdown.

Any electrical issues? Like flickering dashboard lights? On one occasion, we had a loose wire on a 12V chassis relay that shut down the engine intermittently, on another, we discovered one of the engine battery positive leads was not swaged properly, and was intermittently shutting down the 12v system, causing the engine to shut down or not start...

just some things to check. Make sure all house and chassis hot and ground leads bow to stern are tight!

Right. Those problems are not what I had. Mine was definitely due to the particulate filter. As per the scanner. No derate on mine just a total shut down. Then would run for 45 seconds or so then shut down again.
