Will my cr 170 vrs soot more if I remove my Dpf,I've already had stage 1 remap by shark

Of course...However DPF problems only seem to affect PD engines NOT CR ones

They are more likely to be a problem on the PD but the CR is not imune to DPF problems.

As it happens I've been ringing around for quotes and advice on DPF removal.

I spoke to Shark who gave me three options, two of which were 'smoke-free'...

1) Stage 0 (DPF removal but no increase in power) - smoke-free*

2) Stage 1 (DPF removal and increase in power, can't remember exact BHP) - smoke-free*

3) Stage 1 (DPF removal and a bigger increase in power, can't remember exact BHP)

*Smoke free isn't guaranteed however as it does depend on the condition of the engine to start with, however I was warned that due to the vRS having 'straight-out' tail pipes rather than down pointing ones any smoke produced is more noticeable.

My engine is only 3150 miles old so hopefully ok,going to phone shark in the morning

You will also have to have the DPF function switched of within side the engine control unit and also have the vehicle completely remapped.

Any correctly tuned vehicle shouldn't smoke unless you are really pushing for every last bhp figure.

These 2.0CR 170bhp engines with DPF removed and tuned correctly will produce a clean 220bhp with safe EGT's

1 do DSG's get the same amount of power?

2 what costs are we looking at?

3 are the ecu's still being opened on 11 plate plus cars or can they be done EOBD?

4 will the PD dpf off pipe fit a CR so the DPF can be refitted if the car is sold on?

5 if the car when to a main dealer for a sevice after a dpf off and the ecu was reflashed with a up date (like they did with the PD's to try of fix them) will the DPF off need to be re done?

To compare, Shark Performance offer a DPF removal and Stage 0 remap for £449 inc. VAT.

This is a great price, I also phoned around some other local garages and they either claimed it couldn't be done to the PD170, that the front tracking would need to be redone (to access the DPF the suspension needed dropping!?) or they were more expensive.

Don't go for a DPF bypass pipe. I was speaking to my local MOT tester at the weekend on this very subject and he said this would be a fail for him. If the car left the factory with a DPF and it is obviously missing (visual inspection only) then it's a fail.

If the DPF is present (even though it's insides have been removed) and the car passes the emissions test then its a pass.

A nice shiny stainless (and expensive) bypass pipe shouts "look at me, a DPF used to be here!".

1 do DSG's get the same amount of power?

Generally yes, the limits of the 7speed DSG are quiet high.

3 are the ecu's still being opened on 11 plate plus cars or can they be done EOBD?

The ECU will still require removing and opening, it will take many years before the encryption key is known due to the number of bits used.

4.will the PD dpf off pipe fit a CR so the DPF can be refitted if the car is sold on?

You will have to have the DPF Off map removed before refitting the DPF otherwise it will clog very quickly indeed. The pipes are not interchangeable.

5 if the car when to a main dealer for a sevice after a dpf off and the ecu was reflashed with a up date (like they did with the PD's to try of fix them) will the DPF off need to be re done?

Yes, and you will have major problems with fuel consumption until it is redone.

If you are go to shark, they will modify the existing exhaust by opening up and removing the DPF material before welding back together so from the outside the car will look totally factory.

The DPF is not a testable item, so a failure on that point would give the car owner grounds to appeal and possibly cause the tester to lose their license.

I've read the many threads on the latest MOT standards and have yet to see any hard or fast evidence to say that the DPF isn't a testable item.

It still seems to be a bit of a grey area with lots of confusion and conflicting advice.

This was why I went to see my local MOT tester to ask him directly.

Agreed it isn't possible to physically test the DPF (aside from the emissions test) but it is possible to visually inspect it. If there is supposed to be one there but its been removed he said that this could be grounds for a fail. The MOT standards don't appear to refer specifically to a DPF but do mention a catalytic converter which if missing (where one was fitted as standard) is a fail.

I'll be ringing VOSA for clarification before continuing.

It is worth noting that the MOT standards could be updated in the future to include the DPF which could make it difficult if it's been removed.

This is why I'd always go down the route of removing the insides but keeping the outer casing of the DPF in situ rather than removing it completely and replacing it with a pipe.

(to access the DPF the suspension needed dropping!?)

Don't think so

And they wanted £550!

the new MOT standard is PETROL cars from 01/08/1992 have to have a catalytic converter even if it it will pass the emission test when removed

DEISEL cars only need to pass a smoke test. it will be many years if ever if new rules about DPF's are to come in (its taken 20 years for petrol cars)

Hi guys - it's bonus time from work, so I'm looking at getting this done on my 07 PD170 vRS.

Having already had one panic with the DPF (about £400 to get it investigated & a sensor changed by my local independent), I'm keen to get it out of the system.

I see Shark mentioned in this thread, but does anyone have their contact details please, and/or the details for anyone else who does this?

Cheers.

01623 332233 give them a ring you'll not be disappointed,having my Dpf removed on friday

They are the best in the business:

Great - Thanks guys

All ive just had the followig back from VOSA as i am contemplating the removal

"VOSA can only comment on the requirements for MOT. Legal aspects and interpretation of legislation are the responsibility of DfT and they can be contacted through their web site; www.dft..gov.uk

From an MOT perspective a compression ignition (diesel) engine must meet the specific emission limits as prescribed in the Private Passenger and Light commercial Vehicle Inspection Manual (IM). Particulate filters are not part of the MOT and as far as I am aware are not a proposal either.

However, particulate filters are, as their name implies, fitted to filter out particulates [soot] in the exhaust gases and as a method to meet current emission requirements. . It is possible that removing the particulate filter may affect engine performance and it's ability to meet the relevant emission requirements."

I dont know if this just muddies the water a little further or helps

When the time comes, I will be using these in Hinckley Leics...

http://www.r-techpower.co.uk/

Have heard good things about them, £550 for dpf delete & stage 1 map, quite a bit cheaper than sharks £669, plus its only 5 mins from my house !

Don't know whereabouts you are in the country, might be worth giving them a ring...

Great, that's good to know, removing a DPF won't mean an automatic MOT fail.

There are plenty of people on here that have had their vRS's fly through the MOT emissions test without a DPF.

My main concern was the actual DPF removal which seems isn't in fact an issue at all!

Hi guys,

I've narrowed my choice for this down to two outfits:

- JBS in Chesterfield (Linky)

- AMD in Essex (Linky 2)

Both seem to know what they're doing, and are all about the same price. If anyone has any extra knowledge or feedback on them, I'd be grateful to hear it.

I've knocked Shark out, but only because I don't want to gut my existing DPF - just in case it ever needs to go back on!

Thanks

What's the reason for wanting the option to refit the DPF in the future?

Resale or legislation?

As I believe, if the MOT rule change and cars that came with a DPF must have one it's only going to be a Visual check, my DPF was still in place, on my 170PD VRs, so it would pass, but there was nothing in it.

Made the world of difference

Both to be honest. On the legislation side, having seen VOSA declare that anything that originally had a cat now needs to have one. On the resale side, I know people get put off when things like this have been done, regardless of the fact that it's the sensible thing to do, and they could well finish up doing it themselves!

But perhaps not if they bring the particulates in to the test (is that the difference between Euro IV & V, or am I way off the mark with that?)..... And then you'd have to buy a new dpf, which is significantly more than getting a replacement link pipe at the same time as the remap.

I know it's unlikely, but I'm just being really cautious about it.

Dont forget that to refit the DPF the car will have to be remapped again. There is no reason for the DPF to ever be refitted, even without a DPF a diesel car will fly through the smoke test.

Cats have been fitted to petrol engines since 1992, and only now 20 years later has it become testable. it will be many years before DPF's become testable, and by then your car will no longer be on the road.

I am only going to say one thing about JBS in chesterfield. A quick google will show you a lot of recent negative feedback with regards to their workmanship.
