No, Clip is a diagnostic aid tool & gateway for approved software updates not a remapping equipment,
I will say that sometimes there may be a configuration option within the ECU to say with/without DPF but it will still bring lights on as it will detect abnormal sensor readings & parameters when running.
Right ok. So basically it needs to go to a reputable tuner to be mapped out at the same time as a performance increase. I only say that as I'm guessing it would cost the same as a normal remap so I may as well get the tune done too.
I was hoping for an intermediate step as I can take care of the hardware work required in DPF delete and EGR blank myself. A used CLIP would have been ideal for deactivating the protocols and allowing for a cheaper update.
Alas not to be.
I know RS tuning have possibly the best rep for this type of work with experience of working on the 175s. However does anyone know of anybody suitable in Scotland? I'm based in Glasgow for now.
You have to be very cautious if you are doing a EGR & DPF deletion as both have to present for the MoT and if the guts are removed from the DPF it may fail on emissions.
Technically any modifications to the emission systems is illegal and can lead to a crushed car and fine.
If the car keeps on suffering from a blocked DPF find out why and fix the problem.
The MOT also states at present if there is signs of tempering or damage to the system it is a fail.
DPF do control soot by trapping it in a ceramic matrix then burning it at 500+ DegC when either loaded or when driving conditions allow. The thing is, if the ceramic matrix is remove the soot builds up in the exhaust system and when the tester runs the emission test (which measures soot particles) the untrapped soot can give a fail due to excessive particles.
You then have road side testing by the ministry/DVSA/police who will first test the vehicle to MOT standard then the "Construction & use Act" which is much stricter as it applies the standard to which the vehicle was homologated to.
This is the point where there can be a fine or crushing of the vehicle can be imposed.
There is ministry talk that any vehicle which should be fitted with a DPF will have a lower particle limit than currently applied as the filter should be capable of trapping 95% of any soot particles, this could be enforced within a year or two.
This may seem a bit negative but some companies that offer DPF deletion do not mention that it is illegal or a MOT fail and it falls on the owner/driver to suffer any fines, costs etc.
DPF core removal is straight forward on these. Doesn't require a cut and shut and can be done through the front pipe work easy enough.
I'm aware of current legislation. Not future changes. I'm a MIMI and I've missed that bulletin somewhere.
I do 80 miles a day on a motorway mostly above 2500 RPM. The car gets used.
The M9R isn't that sooty with the DPF gone. In fact having been in one with just a CAT (no rear box), even that was fairly clean.
I'm pretty confident about passing the MOT. I still get an old Saab (late 1993) to pass with the CAT removed.
How often do vosa/police stop people for emissions checks? How often do cars get scrapped? All the cars running around without insurance, tax or mot, I'd say it's pretty harsh to scrap a car because it failed a soot test when all else is spot on and extremely well maintained and in fine fettle.
But yeah disclaimers aside, CLIP won't remove it then. [emoji19]
MOT wise I know of 4 cars that have failed due to excessive soot where the DPF has either been damage or the matrix has completely gone (remains were in the rear silencer) so it would be the same if the DPF was deliberately removed & it's this deliberate action which can cause problems with the legislation.
As for crushing, you would have to put a freedom of information request to the DVSA for this, but crushing of a car for a offence is within their powers just as if you didn't pay your RFL or had no insurance, MOT.
we had a visit from DVSA (vosa) in work today.... just checking what they want - the joys of road haulage
got talking to one of the inspectors.... they are now cutting back on road side checks for trucks and buses, and going after bikes, cars and vans....
and they have more power to actually stop you than a police officer! and they can impose what they want at the road side, apart form actually give you the fine and points or crush etc.... thats why they always have a jam sandwich with them!
Only thing I've found in writing from DVSA is that they would "consider" removal of testing privileges for garages that also offer DPF removal or bypass as it is in conflict with the MOT scheme and brings the authority into disrepute.
I'm not arguing that it shouldn't be done or the risks associated with it, rather what's the probability of actually being caught and having action taken?
Most likely scenario is it fails the emission test. Then you'd replace the DPF (temporarily) or go somewhere else.
