Is mercedes pulling a fast one on my dpf

[mioba]

..... some things in the post just dont add up.

Although dealers try things on, there is no way they would remove a DPF.

Seems like the OP has been stung somewhere and is trying to blame the dealer.

Thats my opinion.

Why did the car need a new exhaust when you bought it? You say you saw the DPF and the filters inside but did you see the exhaust filter put that same unmodified DPF onto the car?

It had a slight exhaust leak

 

[Aaron Smith]

Did the op see inside the dpf? The dpf pressure sensor detects if it’s blocked and also if it’s empty.

I had a diag test and everything was perfect all reading 100% apart from map sensor was faulty ut everything else was all good as it should be

I think there's more to this than the OP is letting on.

I think an dpf delete map tricks or tells the ecu that everything is ok, that’s the point of it.

OP come on spill the beans tell us what REALLY happened.

You are a new poster, only ever posted on this thread. Will we ever see you again beyond the story of the dodgy particle filter...

Hi guys just want to know if this is happend to anyone else I had a recall on my car for a airbag deployment earthing but didn't mention a car software update got a phone car to collect the car later on 5hours later seems weird already and drove the car away and it was in some kind of limp mode engine management light was on drive it back got them to diagnose the problem and came up with dpf error due to new software so they kept hold. Of the car for 5days I had to keep on calling to get an update they asked me to come in for a chat didn't seem to good so after the chat I had with the lead mechinc saying the my car does have a dpf has the box but nothing inside it and that's a the rest why my car was going into limp mode but then I asked my friend that does remap etc. And he said this has happend to him and it was a load of crap as my car was reading all OK during that day when I had my remap are mercedes pulling a fast one for a quick buck please help many thanks

You have a facelift 2012 C220 CDI , recall for airbag deployment earthing , what years are affected as I've an earlier facelift ?

Table 3 on page 14. I believe the bottom figure is for DPF cars.

That's old !


Since 20th of May 2018...

Now manufacturer smoke opacity coefficient vin sticker/plate values can vary wildly .

I've a 2003 Euro 3 1.9 derv VAG that is 0.60 and blows sub 0.40 .

It's same engine size newer model late 2000's Euro 4 plate value is 1.00 !!!

Ford's late 2000's Euro 4 are bad as the 1.8 tdci are 1.75 so will be tested to the lower 1.5 default .

Watch those 1.8 tdci spool up with smoke .

As with the manufacturers smoke coefficient value location or being visable from make to make , values hidden by pipes with the plate being on the bulkhead to a separate 0.52 sticker all alone on the underside of the bonnet .

Unfortunately, sometimes when updating certain control units, a Mercedes star system will update a selection of control units automatically. The technician has no say in it. Now I’m not a fan of dealers but I can’t see how they would know if a map has been installed or if the dpf was complete.

get you . at the end its really down to the owner to make sure that dealer is aware of any non std software or other mods , i can see how it happened and i dont blame the dealer either ..and saying that brings a tear to my eye . i will be sure to remember the lesson. if the OP can show that the dealer meddled with the car (i doubt it ) that might be a different matter. hope he gets over the problem.

TBH I think all diesels will smoke, but how noticable.

My earlier Viano V6 didn't descernaably smoke until it developped an issue, even with its DPF it was embarrassing. Having tried many things to resolve I gave up and sold it at a loss to someone who seemingly didn't have issue with it.

My now 2.1 Vito doesn't smoke, as far as I can tell, and I do look for it. No DPF and I beleive it runs as clean as is possible.
I know that larger particulates will be emitted.

Often I drive in traffic and pick up that Paraffin smell, and put it down to a larger diesel wagon up front, an older Landy, or some prat with a stage 1 poor quality remap.

Prior to my remapping this one I have asked if others have experience of additional and discernable exhaust emissions post remap, as I don't want to choke any poor sods behind.

Nice to hear your vito doesn't emit any noticeable smoke M80 as my Vito Dpf is showing 99 percent full of ash in diagnostics but as yet no running issues. Hate black smoke filling the road behind me to be honest. I was thinking of doing a remap, EGR and DPF delete down the line when any issues arise with the DPF. I haven't heard of anybody in locality here being turned down at MOT for DPF delete. I think its still just a visual inspection to check its on the vehicle. Used to be a diesel smoke/Rev test here in Northern Ireland few years back but as far as im aware it was dropped on health and safety grounds for MOT testers

It may be a visual check at present but you can guarantee they'll get tighter on that before long.

Is the UK government going to be all that concerned about catching motorists with no DPFs after Brexit(if it ever happens) when they possibly will not be required to meet EU emissions laws? Im not up on emission laws, but is that not why DPFs where required in first place? Government and car companies are looking set to phase out diesel technology in the near future from what ive seen and heard.

Well at least here in NI with the government in charge of the MOT I cant see any problems with DPF deletes in the near future as they have to build expensive separate smoke testing halls if they want to bring back in smoke test I was told at time of dropping the last smoke test. Only thing i think they could do at the minute is the same idle smoke test they do on HGV test.

My thinking is yes, but I can't comment on NI and if it's different over there.
When you see what London and Bristol are up to regarding diesels it's easy to see that while diesels are becoming 'more' of a cash cow there is also a public sympathy toward these measures that are nowt to do with eu legislation.

I'm sure I'll get slated but after my experiences with the Viano 642 and ****** DPF's I'm looking for a 2010 (possibly earlier) Viano, 646, with no DPF.
Hidden mileage is the pain here as so many are clocked ex taxis.
There is a reasonable looking example at 103k miles, but as it spent 3 years as a taxi doing only 42k miles in that time someone is fibbing.

I think you’ll find that we will keep with EU emissions regs in order to keep selling new cars into Europe and as said there is momentum building not only in the UK but the 1st World for cleaner air so very much the beginning of a new era

 

[ajlsl600]

hope OP gets sorted . i dont really think the dealer wuld remove the dpf. .had it had a recent mot. if it had that would suggest the dpf was there ? if it was not and still achieved a pass i am encouraged .

Totally agree.
We also don't want to end up with a scenario where UK cars are not permitted in the EU due to non-compliance with clean air regulations.
On another note most vehicle regulations are not from the EU but are UNECE based.

 

[ajlsl600]

+1 on above, tho i not sure i trust EU to remain realistic about the matter. you see 1,000,s old diesels here in france it will be interesting.

Never considered thought of UK export car makers affecting Government thinking but I do see government thinking in cities regarding health issues and public views swaying the argument towards at least keeping DPF,s. Maybe they should penalise city drivers and let the rural drivers fume into the open countyside

Dont shoot me for mentioning an inferior make on here but wife,s Santa Fe has had issues since start of summer with flashing engine light. Its been with dealer for the third time now. left it in last Monday and its still there, changed sensors this time and no joy now they have raised a technical case with Hyundai so DPF off for inspection start of incoming week and possibly new one fitted under warranty thankfully if thats the problem and Hyundai authorize it. Hoping that sorts the issue out as dealers is an hours drive from home. Up to now I believed DPF,s were for the greater good, But now im happy to get a work around after Hyundai warranty runs out in January if the issue reappears
