Been looking at this online and would like to know people's thoughts on this process ? Anyone had it done and what the pros and cons are ??

Thanks Sam

Pro's: Eliminates potential DPF issues, improves the smoothness of the drive, increases fuel economy, saves weight.

Con's: It costs around £400, the car will smoke, may make it more difficult to pass the MOT soot test, could affect your insurance, voids warranty.

I was wondering about the mot test .. Has that been a problem at all with people ?

How does it effect insurance ?

No probs if you give it some welly on the way. Or floor the throttle a few times to clear the soot out before you take it. Millers helps as well.

Wrong, find the right place, i paid £150. The car will not smoke any more then a standard diesel, something you will not even see out of the rear view. Mine passed an MOT last month at a Skoda dealership with a stage 2 smokey map on and it passed with flying colours. Does not effect insurance, only a map will do that. There is no warranty on your DPF, it is classed as a filter.

It's a mod - you should notify your insurer

Get it done at a 'tuning' place that does MOT's too and then take it there every year. They wont have the cheek to fail it on the 'smoke' test if they've removed the DPF. That's probably what I'd do if I ever need to get it taken off.

Far from wrong actually.

A DPF equipped car doesn't smoke at all. A car without a DPF will smoke. The bumper and bootlid of your vRS shows just how much it does smoke.

A stage 0 map smokes the least but it will still smoke, you just can't see it from the drivers seat.

I didn't say it won't pass the MOT, I said it will be more difficult to pass the soot test. A non-DPF equipped diesel smokes so will register a reading on the soot test. Some cars smoke more than others. If it isn't driven very hard prior to the test then the high revs required for the soot test is likely to record a higher than normal reading.

It will affect the insurance as it is classed as a modification. The fact the DPF is a filter is irrelevant (we all know it is more than a filter too), removing it is changing the car from standard. The ECU also needs to be mapped to stop the car reading the various sensors. This requires the ECU to be coded which again is a non-standard modification - all of which require you to notify your insurer. It may not affect the premium but not telling them could void the policy in the event of a post-claim examination.

It will also effect the warranty as the car has to be mapped, which requires access to the ECU which is more than enough for Skoda UK or a third-party warranty company to refuse a claim.

If you are trying to tell me your vRS doesn't smoke then I think you might be smoking something too!

Holy crap,I'll say that car has a 'smoky' map.

I had the DPF removed by shark and a Stage 0 map ( PD TDi Vrs Octavia )

Smoked a little but flew through the MOT no problem, and it ran better. No noticable smoke though even under power

Think it may depend on who does the work

I also had my DPF removed by Shark. (cR170 TDi in an Audi TT) and has been emissions tested by 3 different places and all 3 passed it. It does smoke a little on spool up (2500rpm) but it's very light really and the DPF is physically still present, so it's legal for the MOT.

Forgot to add, the DRF was still in place on mine also, there was just nothing in it.

You cant use mine as an example, thats a stage two AND having just freshly come back from the nurburgring, not it was used for track but mnany many motorway miles.

Like i said a non DPF car will smoke, as much as a normal diesel does, which tbh on a well maintained car is hardly nothing but mine IS a smokey map and still had no problem come MOT at a Skoda dealership which tbh i think are going to be the most stringent.

How will effect warranty when there is not even a manufacturers warranty on it? The ECU modification only stops it from regenerating, so the software that is being removed for the part that has been removed, it will affect nothing else on the car.

Insurance, i have rung them, told them about the DPF (which came off about 2 month before the map went on) and they said that this does not change the insurance nor will it be recorded as it is a wear and tear product.

Have i missed anything out?

Slightly suprised on that, changing an air filter is only a filter but Innsurance companies seem to like to know. With anything like this Insurance companies being what they are keep a record of the time you called & the name of the person you spoke to or better still send an e-mail as confirmation of the call, it will probably never be an issue but if it is you will only know about it when you claim.

Completely off topic but are there any more pics/spec of this?

Looks good.

My first post you labelled as 'wrong' was aimed at the OP not your car. We don't know if the OP's car is under warranty or not.

He was asking for the potential pro's and con's of removing the DPF.

I said it'll smoke, we both agree it'll smoke.

I said more soot will be emitted from the exhaust. More smoke = more soot.

I said that a car that generates more soot may have problems passing the soot test during the MOT. I didn't say it was a guaranteed fail. By your own admission you drive your car hard. Someone who doesn't (at least directly prior to the soot test) may have issues passing the test.

Not everyone is insured with the same company as you. Therefore my advice that is could affect the OP's insurance was valid.

I'm still unsure as to why my post was 'wrong'.

The most notable effect after having my dpf removed (by Shark - be very careful who you use for this) was the massively improved response to the throttle.

The difference is like driving with the hand-brake off after having the dpf removed.

Does smoke when giving it the berries though!

It was wrong as the way you came across, i think pretty much every vRS i know has the DPF removed, them like myself have never experienced any issues with warranty, insurance or MOT. Smog is a different topic, if you truly do not want you vehicle to smoke, by a petrol. In my opinion all diesels should smoke and these daft silly filters are just a ridiculous

Someone asked about the Blue Octy that has been posted, thats mine 170PD Stage 2 map, KW V1 inox's and Dare LP5 alloys (although im back to OEM alloys as of today) the perfect road use diesel if you ask me!

Why on earth do you think all diesels should smoke??

Because all diesels do smoke to a degree?

I'm taking it further off topic but do you have anymore pics and how is the ride on the kw's? I want to lower mine but the wife is worried about the quality of the ride especially now we have a child.

Because if they dont smoke they have a dpf, that eliminates smoke by breaking the nasties down into even smaller particles so unlike soot which just damages lungs the fine particles can pass through the lung into the blood stream & go through your body, time will tell but I think we can all judge on where this might be leading.

The Horse & cart was fairly good to the enviroment, every stage after that just brings more & more issues & technology to solve each raise more deamons in a few years, its called progress

Slightly suprised on that, changing an air filter is only a filter but Innsurance companies seem to like to know.

If I was an insurance company, the filter itself would mean nothing, but any client who thought it was a good thing is probably taking advice from way too many muppets and is likely a liability for that reason.

The ability of an insurance company to prove a map has been is altered is questionable. They would have to find the original ECU dump from the car, pull the current bin file out and compare the two.

I don't know where this idea comes from. Only unhealthy diesels or those monkeyed with smoke. It could be the number of dirty tunes on the road is so commonplace that the general public thinks all diesels do that.

Only a diesel with a DPF will have a clean exhaust tip inside. But without a DPF no smoke after startup is the way it's supposed to be.

My JabbaSport mapped car with DPF removal smoked a little but only really noticeable if it had not been driven hard for a bit. It failed its first Mot due to this issue but after a blast by myself it passed ok and every subsequent mot.

I personally highly recommend the DPF removal as I had no end of issues with it; my journeys were not short ones either but 2 hours per day of non town driving.

If you do decide to get it done, do not go for the DPF delete pipe as this will fail an mot as the tester is looking for the DPF physically. If you get the innards removed the tester is none the wiser.
