My Hymer is poorly sick

hi
you might be able to do a forced re-generation with that software.

Yes, it can, but it fails because of the sensor fault. If I clear the fault it starts to regenerate then the sensor error gets logged and it fails. I did this 30 times and managed to get the clogging from 68% down to 40% so it is doing a 1% regeneration each time. I can drive the van now, but it has little power due to the back pressure. Hopefully, once the sensor is changed it will complete the forced regeneration.

As you know I do a fair bit of work on bikes but not cars/vans. For most bikes you can get exploded parts diagrams or microfiche diagrams on line giving part nos and the location of parts. Might there be something similar on line for the motor in your van so you can locate the duff part.

The problem is that Hymer moves things around when they convert the standard van to an A-class. The inner flitches are removed and anything on them get repositioned.

Think it’s will be a case of tracking them pipes for splitting or as you stated popped off a possibility

Yes, I need to get under the van so that I can trace the pipes. I am going to wait until the new part comes.
 
Those DPF’s can be rather expensive through dealers so hopefully it won’t need replacing. If you have a faulty sensor are the readings of 68% true Phil?

My van is a 2013, so no adblue.

Phil change it for an old Talbot Express. You can buy one for less then all the meters and testing equipment. Also you don't need any PDF stuff. It will also help tone your body if you get one with no power steering. Its like wrestling a Rhino and will put muscles on yer tongue.

PS hope this was helpful. Hope to see you at Henley if I can escape.

A lot of folks have been using oven cleaner to cleanse dpf filters when removed

Not Sure, I will find out once I have fitted the new sensor. However it is better now I have cleared it to 40%, it can idle now.
 
Oh dear it looks like one of those weekends. I was driving to Cumbria for the weekend away yesterday, we got about 6 miles down the M62 and next thing a loud thud on the windscreen and yes cracked across the whole window. Now waiting for autoglass to call me and give a date when they can come and replace it.

We’re not having much luck the now guys ,prob start raining next ?????
 
We only do 20 miles a week in Portugal. We get similar problems. DPF or ERG, gumming up.... A tankful of mixed diesel and super diesel , works wonders. Don't know if there's a downside to this, though?
 
You might need a washout of the actual filter if the regeneration hasn't happened, There might be a sensor at either end for the ECU to compare, the oxygen sensor would look similar. Once you find them then should be easy sailing. Mercedes dealers will probably not tell you anything of worth as they want those jobs, but maybe not on an A class.

I have ordered a new sensor after reading a post on another forum from someone with the same issue. They used the same software and got the same readings from the sensor and it turned out to be a faulty sensor.

The sensor cost £26 including delivery. Now I just need to find it!

Check your letter box regularly
 
I hope you get it sorted out phil :) :)
 
I have had a thought about this and it might well be a stuck EGR valve. It is the weak point with all the sprinters and can happen as low as 25000 miles. The MB Way is to replace the whole thing but the valve is easily cleaned with barb cleaner. It is difficult to get to on Aclass vans because of the front postal slot access but normal ones dead easy.
It lives beside and under the oil filler spout which is removed with a torn bolt then pulled up. The valve is a three bleed propellor like device over three holes. It gums up the dry car one and the body gets filled with soot and gum..it is opened by a little servo motor but snaps shut with spring force. Gumming stick it open so according to the usage will block . Athrashed hard motorway delivery van will last lot longer than a town one which can maybe block in 10000 miles.MB will replace but it is a service job to clean them for self maintenance firms .
If you still have problems after the filter clean then try this one. The service light might or might not come on. I have a service code reader to put them off .
