DPF removal issues.

[V6Matty]

You could try sourcing a second hand unit and have them fit and recode the car,

Second hand is still quite expensive, like I mentioned I've not had much luck with the vehicle. Constantly something is fixed another thing goes.. and I do a lot of short journeys so I am not sure its wise as I'd be wary of it blocking again? At the moment I am stuck with the issue.

 

[Craiglxviii]

Sure. But, and this is the key issue, your car is, y’know, ILLEGALLY MODIFIED right now, it’s moved away from it’s homologated condition, an MOT failure and so not roadworthy. You need to fix that!

In reality. Makers don't advise prospective owners of these cash grabbing systems, just like they will sell 3 ltre cars that can't legally tow anything , and sell 4x4,s that can't pull anything without 4k of upgrades. If there was an obligation to inform buyers some wud walk and find a motor sans all this kit that often they can ill afford
Also if makers were "forced" to make the kit reliable or more economic to purchase, a 10yr emissions kit warranty wud fix this inside a Yr. And 600 plus for a plastic tank to get a 10 qiud sensor most would just do the right thing.

Thing is 1000's wonders of diesel cars do not have a DPF purely because its much cheaper to cut it out and fuel consumption is better and car runs better etc etc. I decided to cut it out as my dpf was completely blocked and kept on blocking pretty much every month. So of course I went for a "cheaper" option which is not so cheap in my case anyway..

If I was in position where I could splash out cash I would get new dpf and coded. However like I mentioned I am currently not. Therefore that's why I am just asking for any suggestions or advice.

Run your hand over each intercooler hose and check for oil on it. If it's oily it's possibly leaking.
Look especially at the inside of bends and the areas near the end of hoses.

I wouldn't even know where to look for. I mentioned that to the "local garage" they said we need to find out if dpf been removed properly, they said it been removed but catalyst converter is still there? They also said there was no leaks on intercooler hoses.

Whether it runs better and has better economy or not we must keep it fitted by law.
The reason I'm so hot on this is I bought a car from a dealer where someone had removed the DPF and I found out after purchase. It took months of emails and threats before they agreed to contribute to a new one. It created a lot of hassle for me that I should not have had.
They then went after the person they purchased from.
It was pretty clear from diagnostics when it was done so easy to track down.

Boost pressure must be leaking somewhere.
If it's not boost hoses then PCV valve could be failing though I'd expect other issues.

Intercooler hoses are the big rubber ones about 2" in diameter that run from the turbo to the intercooler then intercooler to inlet manifold.

Bollocks. Thousands of diesel cars don’t have a DPF because they were Euro III. Sure, some owners removed DPF, some removed EGR but they’re in the same boat as you; since the changes to the MOT test those cars are now illegally modified and not roadworthy. That’s an excuse to cover your actions, not a good reason!

Your problem could have been sorted by taking the car for a good Italian tuneup then forcing a regen each week.

Any advice you get here- and Lostkiwi is giving you excellent stuff- still doesn’t return your car to a roadworthy legal condition. That’s an obligation on you unfortunately.

It's not an excuse, every single person is in different situation and you make decisions based on the financial situation you're in. I was in situation where, I could not afford a new DPF therefore I went for a cheaper option and that's that..

How’s the cheeper option working out for you

 

[V6Matty]

Only other option might be to see if you can find a local scrap year that has the car in

A mobile remapping company did the DPF mapping for me not long ago as well as EGR delete. Apparently he said it could be something to do with MAF sensor. In the worst scenario, if I can't fix it. I'll just buy a second hand DPF and I'll get rid of the car ASAP and I'll get a petrol.

 

[dry run]

I feel for you Da1992. I get why you did what you did and I'm not judging you, but you have unwittingly dug yourself deeper in the brown stuff. I can't see a cheap way out of this. You can't really sell the car in it's current condition and driving an non roadworthy (legally anyway) car is only going to get you so far. Second hand DPF, coding, selling would be my best suggestion. Anyhow, hope you find a way out.

 

[LostKiwi]

To get coding returned to standard check to see if your car is due the emissions recall. If so that's a free way to get it recoded back to standard.
You should be able to pick up a used DPF from a scrapyard for around £200-300.

First of all though, fix the issues while you can see them in the rear view mirror.

I will take it to specialist and see what they say. If they can't fix it and the only way is to install a dpf and code it then that'll be it and I'm getting rid of the car.

Yeah, I'll have to see if the black smoke and the air leak can be fixed as some of people I know had their dpf cut out and they don't have any issues or black smoke. Would it be more useful if I actually recorded a cockpit video and you could actually listen to what I hear?

After market isn't daft, I've done over 10k miles on one of these.

MERCEDES VITO & VIANO 2.1 CDi 07/10-12/16 DIESEL PARTICULATE FILTER DPF (EURO 5) | eBay

Diesel Particulate Filter. Once the fault that caused the previous DPF to fail has been rectified the new DPF can be fitted. The new DPF should be fitted loosely to line it up correctly with the rest of the exhaust system before tightening it up.

Installing a DPF w/o restoring the ECU to factory wouldn't last more than 1,000 miles or so. The ECU wont cause a regen so the DPF will cake up till blocked.

Can the ECU be returned to factory via Star at an Indie?

Here's a short video of the noise I'm getting under acceleration. Perhaps this would be more helpful rather me trying to explain it.
