Please Help; Germans Stranded in Mongolia

I am currently in Mongolia and there are some lovely german people staying at the same hostel as me. They have their Daily 70-170 camper here which has gone into limp home mode with some check engine lights on.

We have read the manual and deciphered that the series of engine lights means that there is a problem with the exhaust system, which I am currently assuming to be a blocked Diesel Particulate Filter. This makes sense as there is low quality fuel here and, the problem started they were driving slowly on bad roads for hundreds of kilometers which would make it difficult for the filter to regenerate.

My question is, I've seen that it is possible to manually trigger a regeneration cycle and that an oil change is required after that process is completed, but I cannot find how to trigger that process.

They have a diagnostic reader coming tomorrow from Europe, but i don't believe this is the fix, as this will only allow them to read the codes.

They do however have a Dimsport New genius 2 which was provided to them from the factory to switch from Euro VI to Euro V as there is no Adblue available here in Mongolia. This thing appears to be a more fully functional ECU reader/Writer.

They are willing to drill the DPF, but I have heard that this is a last resort if the manual regeneration fails.

Can anyone on here please help - These guys are super lovely but not very mechanically minded. I'm just an engineer staying here trying to help out.

Hi,
I recommend that you first replace and reset the engine oil.

Reset the engine oil change:

Switch the ignition on, wait a few seconds until the cluster do the check, then press the accelerator pedal and start the timer, after 15 seconds start to press brake pedal 10 times, without releasing the throttle pedal, next I switch the ignition off, then release the accelerator pedal.
After 30-40 seconds start the engine and the warning light must be off!

Regeneration on demand:

Stop the vehicle on flat ground, away from traffic and pedestrians. Be sure not to be flammable material under and around the vehicle.
1. Set the gear in neutral and apply the parking brake.
2. Switch off the engine, then switch the ignition to MAR-I
3. Press the brake pedal and the accelerator pedal at the same time, and wait for the DPF warning light to blink, and the cluster to display the message "Cleaning DPF start the engine and keep the vehicle stationary".
4. Release the pedals.
5. Start the engine without pressing any pedal (throttle, brake, or clutch). The DPF warning light will start flashing. If the engine fails to start, repeat the procedure from the beginning.
Reg on demand could stop automatically if there are system failures as sensors or else.
Regeneration is complete when the DPF warning light is no longer flashing:
- if it goes out, it means that the procedure has been successfully completed;
- If the warning light remains lit, it means that the procedure has not been successfully completed and must be repeated by eliminating the causes that have caused it to stop.
After the regeneration is complete, reset the oil once more.

Hi Bazil

can you please tell me, if this "Regeneration on demand" and "Reset the engine oil" procedure is an "official" IVECO instruction in an emergency case as described by bapo?

Did you ever tried this yourself and does/should this work for all Daily Euro 4 & 5. Does this run at ~ 3000rpm - i think

I am interested in this stuff, because I know many drivers of Daily 4x4 xxS17/18W 2007 and up and also Bremach with the F1C E4 & E5, witch are often travelling in Asia, SouthAmerica, Africa etc....

I am Mod in the German viermalvier.de forum. But I do not have a 55S17/18 to test it - I own a 97er 40.10W

Best regards & Thx
Juergen

Hi,

The reset procedure is tested on Euro 5 models. Marcus has found this procedure and is from the SCAM user manual. I personally tried it on a few Daily 4X2, Euro 5 (MY-2009-2012-2014).
The on-demand regeneration procedure is from the Daily MY-2014 user manual, so it's official but I have not tried it yet. Daily 2014 may be Euro 5, or 5+ (Light duty), or Euro VI (Heavy Duty).
REG procedure, may not work on older models. Over time the EDC software has evolved also evolved the hardwere side.
I used, as a description, the same Model of the Year as 4X2, but actually the 4X4 models appeared with a one-year delay.

To return to the regeneration procedure, it is essential that regeneration of the DPF to be done normally and the service regeneration, also the one on demand, should be done only as a last resort.
It is also important for the engine to be at working temperature, ie 80 degrees Celsius. Do not try to regenerate at lower temperatures, as it is possible to fail.
A service regeneration lasts for at least 20 minutes, and automatically sets the engine between 2500 and 3000 rpm. It's possible to be the same at REG on demand. A shorter time may mean regeneration was unsuccessful.
In most technical documentation the attention is drawn to fuel quality, but there are few that specify the importance of oil.
If fuel quality can not be a choice because of the area, instead, the quality of the oil can be. An oil that is not Low SAPS will speed up the ash growth in the filter.

N.B.

"Service regeneration" means forced regeneration, done with the diagnostic tool.

Thx Bazil for your respond & explanations.

it`s interesting that the on-demand regeneration procedure is described in the (14er) Daily user manual, unfortunately I don`t have one and did not find one on the I-Net.

Does IVECO make any limitations/restrictions to use this procedure ? (in the user manual)
And yes of course, the on demand regeneration should be used only in exceptional cases.

It seems possible to trigger a "service regeneration" with a cheap Delphi clone too. But more important is, while travelling in areas with high sulphur fuel, to check the load of the DPF from time to time....

And I agree with you - Low SAPS Oil is important.
