A220D Exhaust flaps error - following remap/DPF delete

[RAGEisDEAD]

Hi All,

Yes I am new to this forum so not sure if this is in the right category but it seems most fitting and I am coming here with my tail between my legs as I have a feeling I have F'd up so to speak, and I'm sure many people wont be able to resist telling me that, and I'm all for it .

Anyway... Looking for some help/advice.

I have an A220D 2.0 had DPF issues over the recent months and thrown loads at it, manual regens/ mobile DPF cleaners etc it always came back (and I know its my fault or not taking it on long drives)

Anyway I was recommended to have it removed so I had my DPF "removed" cut off, removed and welded back and EGR deleted and stage 1 remap by a tuning garage they claimed the first time EML came on they had to then welded open the exhaust flaps and map it out.. it then returned (EML) pretty much straight after leaving so he then said it was an error about camshaft sensor, but I wasn't convinced so had it diagnosed by another MB specialist who found codes coming up as P13C271/P13C21E Exhaust flap 1 has malfunction the actuator is blocked and malfunction, resistance value is outside permissible range.

they said to take it back to the tuner and get him to either unweld the flaps and they can have another look or did the tuner forget to map the flaps out of the ECU when welded? IDK

I had so many issues with my DPF I was advised to have all this done and now I'm regretting it as it just one thing after another and the tuner wont take on mechanical work so I am being passed around garages.

I have found an actual MB specialist who sympathize with me who I will be going to moving forward, but at the moment they advised to take it back to the tuners and see what they say but its occupying alot of my time having to taxi around etc.

Would you give the tuners another try to map the flaps out or just get them to un weld them and go elsewhere from here..

Has anyone got experienced with this unethical process of removing the DPF /EGR delete ever had to do anything about the exhaust flaps?

this is the service these guys offer:

"The Diesel Particulate Filter removal involves removing the internals of the actual DPF. Remove existing particulate filter from the vehicle, cut an opening, remove the core, clean and re-seal by welding, Refit back to the vehicle. Then remap the vehicle to remove the regeneration software from the ECU and remove the DPF warning light from the dash."


Any advice would be great

TL;DR had car DPF removed and EGR deleted along with a stage 1 remap, now exhaust flaps code is showing however tuner claims to have welded them open and mapped them out of ECU but MB specialist claims exhaust flaps are causing the fault and i have a diagnostic report to prove that. what do I do?

Since your car is no longer road legal, uninsurable and the mods you have done are all illegal (Stage One aside) and it can no longer pass a MOT and this forum has rules (not always acted upon to be honest) about discussions relating to illegal activity I doubt this thread will last long before being deleted by the mods. Best of luck sorting your issue though.

It appears the garage messed up your car.

In writing, recorded delivery, give them the opportunity to fix or reinstate (or settle with you) and if not resolved, then issue legal / small claims court.

And do it ASAP as you are in danger of being undeclared uninsured with a car that will fail the MOT

Good luck

Keeping in mind that the car is also equipped with AdBlue, which is a whole world of pain on its own if it goes wrong, my advise would be to reverse the DPF delete, fit a second-hand known-good DPF, then get rid of the car by trading it in, or by selling it to the likes of WBAC/Motorway/Carnow etc.

Sorry if this is not what you wanted to hear.

Yeah I know all of that and it's causing me too much money and hassle so I'll take the risk, try not to make me out as some criminal because I have gone against the policies set in place by Tyrants who whilst enforcing environmental policies are all flying around on private jets

Mine does not have adblue thankfully, I will give the tuners one last chance to rectify, if not ill bang a second hand DPF on it.
Only issue is it will take me a month or so to get the money meanwhile I still need to use the car for work and don't want to do any more damage, I'm just driving super slow in limp mode atm.

Thank you for the advice mate I have until November to sort it.

They have one last chance to rectify (going in tommorow) and based on what happens ill have no other option than to refit a DPF and get someone to map it back in and just take it for a long drive every couple weeks.

Yeah they advertise it as a fully legit service, claim they can have it pass MOT's and to be fair I know 2 others who have had it done and had the cars subsequently MOT'd fine, Ithink they just either arn't experienced with the Merc DPF/EGR system or just missed something I was hoping there'd be someone who had done this with their car and knows why the flaps maybe flagging, but this forum may not be the best place for illegal modding as pointed out by another user.

So, when it fails the MOT what is the plan?

Justifying actions based on those of others isn't rational.

I was told It will pass the MOT Emissions tests due to the remap put on it and the DPF has been gutted and rewelded on the exact same weld line so unless someone takes off and physically inspects the DPF they will not know.

So my answer is I guess ill find out when it goes for MOT.

Who do you think you are mate?

Sat on your high horse on a web forum, I literally said I was happy with the responses, you are all armchair warriors don't know **** all about my actual technical question just ranting about laws and policies, why even bother commenting?

You don't even own a mercedes.

Most of these mappers keep the original file and offer to re instate if not happy.
Best choice here imo.

To de weld isn't likely to leave the exhaust flap to move freely,
maybe a 2nd hand part there is best.
That would surely eliminate the need for the MB specialist to interrogate and resolve that.

I've fitted an new after market DPF, it was near 40k miles ago at around £400 (maybe more).
But the ECU does need to be told it's new, and reset to zero values.

The long drive theory is ott. But I do monitor mine to see if it continues to regen every 400 miles or so.
I've seen mine go back into regen after not completing one. It did this at 40 C (that was engine not exhaust temp).

Always better to try and resolve the issue with DPF rather than gut and remap.
Yes it can be done and not be picked up at MOT, but as you've learnt it can be the start of other issues that the remap can then be the cause of / blamed for, but how to know?

Personally I feel any remapping is better done on a proven well running engine, all fault codes looked for and any issues resolved.
Yours may have been merely a duff DP sensor.

Your political comment is whole different argument. I have sympathy with it, but it's irrelevant come MOT, Insurance, or even VOSA issues.

Good luck, you may well need it.

Hmm... as far as I know, the A220d 2.0L does have AdBlue... has it been deleted in the past?

EDIT: Just saw the OP's request to close the thread.

Who do you think you are? I think we clearly know You really do have a chip on your shoulder

Arrogant over entitled keyboard warrior mouthing off on a web forum (see the irony here?) typical of many who come here, add nothing of value whinge like children when someone does not agree with you!

I do own a Mercedes, an SL 500, I just haven updated profile which is my business not yours.

Another idiot for the ignore list. (which means I won't be able to see the drivel you will undoubtedly continue to post!.. Bye now

Oh surely not the pot calling the kettle black.

I am posting for technical help if you do not have the knowledge to help. you are literally adding NOTHING OF VALUE, see the hypocrisy?

"Arrogant over entitled keyboard warrior mouthing off on a web forum (see the irony here?) typical of many who come here, add nothing of value whinge like children when someone does not agree with you!"

The truth is you speak to people how you want to be spoken to unless provoked, you provoked me by trying to be a forum moderator which you are not also twisting my words (claiming I was unhappy with the responses after I stated the complete opposite) so it is what it is.

Wind your neck in


GOODBYE

I appreciate them time you have taken to respond, they did offer to map it back to default if I needed any reassurance.

I will see if they can resolve it tomorrow, if not ill have an aftermarket DPF fitted back and live to learn from my mistakes.
