Hi All,

 

Pulling my hair out again with DPF.

 

Purchased Octy CR170 last November knowing it had DPF delete and remap .... due to DPF filling up to a level whereby needed a new one at cost £900 by previous owner (i was assured its passed each MOT no worries)

 

Cue my failed MOT yesterday for DPF Tampered on visual check however they never tested the emissions(stating didnt want to put it under load as low oil - oils fine). Halfrauds quoted £1070 ! On a car i paid £2800 .... ermmmm no.

 

So where do i go from here as i said it could have been cleaned out but they want to see proof and i dont have this.

 

Is there any companies that offer a full DPF with a letter saying this has been done so i can retest at a reduced cost than having to buy a new DPF and remap back to standard at cost and possibly an issue with EGR also?

 

Only had this car less than 6 months and want to get rid of it with this DPF issue.

 

The cars engine runs sweet as nut and i love all abt it but this DPF issue is draining.

 

I get the soot level and environment etc but families do this due to excessive cost.

 

I just want a cheap car thats reliable that runs sweet and save money trying to get to work to feed the family.

 

If i wasnt bothered abt money/environment id buy a range rover guzzler like others do ... Who has 1k they can pull out the bag just like that.

 

Always the working person hit.

 

Thaks in advance

Is there any companies that offer a full DPF Clean with a letter saying this has been done so i can retest at a reduced cost than having to buy a new DPF and remap back to standard at cost and possibly an issue with EGR also?

I'm not sure a reputable company that cleans DPF's would want say it's been done given there is no DPF to be cleaned. Seems like an easy way for them to get in trouble.

 

I think your choices are:

- buy a new DPF and have the car returned to stock or mapped to suit

- buy a used DPF, possibly have it cleaned and have the car returned to stock or mapped to suit

- find a dodgy MOT place

 

Given they are cracking down on DPF removal, I'd probably choose one of the top two options. As a FYI, some people claim that aftermarket DPF's don't last as well as genuine ones...

 

Hopefully the car was a bargain as it's likey making it road worthy will take a fair chunk of whatever savings you made 😕

?

Have UK MOT tests been suspended yet meaning for 3 weeks or more no need to get a renewal as it is only Essential Workers working?

?

Does that mean it is get a retest today if you can anyplace or your car is going to have to be off the road?

Not yet.

 

At time of writing, only MOTs for HGVs and PSVs have been suspended for three months: https://www.gov.uk/government/news/driving-tests-and-mots-for-heavy-vehicles-suspended-for-up-to-3-months-to-help-tackle-spread-of-coronavirus

Cheers.

So, Published 20th March 2020.

 

They will need to get their big boy pants on and thinking caps, because NHS / Police / Emergency Services and essential workers will need their private car on the road and legal and insured and them driving in accordance with their licences.

If you want to save yourself future grief, buy a petrol and one that is nearest dammit EuroVI compliant

 

I've recently jumped ship from diesel to petrol due to the unscrupulous behaviour of car companies like VAG and people like yourself who knowing drive around in vehicles with DPF delete and other emission cheating 'mods'.

 

The main concern of people who do this is whether they'll pass the MoT. The general consensus on various forums is that it's not a problem, however, some local authorities  have 'pulled a binder' by banning diesel vehicles totally. It is only a matter of time before more towns and cities adopt this policy.

 

From 2022 you can no longer drive a diesel in Glasgow that is less than  EuroVI compliant, Euro IV for petrols. This will be enforced by CCTV with a fixed £75 (ATM!) fine

 

I was intendingto keep my vehicle for a good few years, but had to sell it early to avoid a crash in diesel trade-in prices as 2022 approached.

Euro 6c has introduced particulate filters for DI petrol engines.

What's the scrap value on your car? It might work out cheaper overall.

The value of Scrap / Scrap Cars that needs collected might well be an issue for the next few months.

And now they have: https://www.gov.uk/government/news/vehicle-owners-to-be-granted-mot-exemption-in-battle-against-coronavirus

 

It states:

Quote

All cars, vans and motorcycles which usually would require an MOT test will be exempted from needing a test from 30 March 2020. Vehicles must be kept in a roadworthy condition, and garages will remain open for essential repair work. Drivers can be prosecuted if driving unsafe vehicles.

 

However, given the OP has already failed an MOT it probably won't help them. If anything, it'll probably hinder given they need to make it roadworthy and get an MOT :/

You need a new DPF. A DPF clean won't work as there is nothing to clean.

 

When the DPF is 'deleted' it is either removed completely and replaced with a straight-through pipe, or the DPF casing is cut open, the insides removed and then welded back up. The sensors that control the DPF are then coded out so that you don't get the warning lights on the dash.

 

Either way the MOT tester is able to tell visually that the DPF has been tampered with. To clean the DPF you do not need to cut it open, so the fact the MOT tester has been able to identify the weld they are well within their rights to refuse to issue an MOT certificate.

 

When did the previous owner remove the DPF? You can enter your cars registration number here to view the cars previous MOT history and to see if it has indeed passed an MOT since the DPF was removed, or if it's received any DPF-related advisories...

 

https://www.gov.uk/check-mot-status

 

Unfortunately I suspect the previous owner has either used an unscrupulous MOT tester, or has lied to you.

 

Halfords is never going to be the best place for a new DPF quote, you need to find a DPF specialist, or a trusted local garage with low labour rates and access to non-genuine DPF's. I'm afraid even this will cost you between £500 and £700. It'll also need someone with access to VCDS or VAG-related diagnostics software to reactivate / code the DPF sensors...

 

 

 

 

I had DPF issues with my old PD170 vRS, I considered a DPF -delete and figured it simply wasn't an option given the current legislation so I chopped it in for a Skoda Superb.

 

Why the previous owner thought it wise to remove the DPF is anyone's guess. Even if it was full of ash then a professional clean can significantly extend the life of an existing DPF.

Was the remap a performance upgrade, or to simply code out the DPF sensors? If the former then he has naievely removed the DPF in the pursuit of a smidge of extra performance, quickly realised his mistake and sold the car under false pretenses by reassuring you it'll pass it's next MOT.

I am not sure if I understand this, please correct me where I am missing something.

 

The vehicle has failed an MOT because the DPF is missing or has been tampered with, the emissions test was not done because of a low oil level, would they have tested it if the oil level was correct knowing it had a DPF delete?

 

If you can get a reciept showing that the non existant DPF has been cleaned the retest will be cheaper?

 

Would a vehicle (re)tested for emissions meet the standard with a non functional or missing DPF?

As an aside and perhaps of no relevance, to facilitate my getting my Yeti registered in France before bringing it over from the UK (to avaoid ANPR & road tax problems) I got a UK MOT on it, the tester an old friend passed it with a commebt saying that the emissions could not be tested because the vehicle would not rev beyond 2.5k RPM at standstill.

 

I think this applies to most post 2012 Skoda diesels, my neighbours Octavia is the same althiugh he had never realised. Could this be a way around the emissions test problems?

 

Have any of you had the same thing with MOT tests skipping the emissions test?

 

My 12 month MOT is now valid for 24 months in France not that I can drive anywhere in the confinement and the temporary (1 month) registration certificate expired yesterday, they wont be back for 4 months to issue the definitive one.

Correct, the MOT tester has spotted that the DPF has been opened / tampered with. This alone is enough to fail the car.

 

 

The MOT tester knows that evidence to show the DPF has been cleaned doesn't exist, the evidence it has been opened and gutted and not cleaned is there for him to see.

 

If the tester still wanted to carry on with the test, diesel engined cars are put through a smoke / soot test, a probe is inserted into the exhaust pipe, the engine reved and the levels of soot are measured. For fear of damaging the engine the tester will not be willing to rev the engine knowing the engine oil level is low.

 

 

If the DPF has been removed, gutted or is inoperative this should be evident from the recorded levels from the soot test. A fully present and functioning DPF will record a zero reading in the test.

 

There is no point retesting the car until the DPF is replaced. A receipt for a DPF clean won't be enough.

So you knew it was unroadworthy (in the eyes of the law) and most likely to fail the MOT.

No. In this instance, its a case of wishful thinking. 

 

The fail and the reason is now on the MOT history database for any prospective purchaser to inspect.

 

Only solution: fit a new DPF.

You can't code out sensors via diagnostics, it requires a remap to get the ECU to stop monitoring DPF function. Rectifying this will require a further remap to return the car to the stock ECU map.

Yes you can, at least on some VAG models, there is plenty of content online where it has been done.
