#332514 New Mot Requirements ( Dpf And/or Catalysts )

Posted by wase16ll on 14 February 2014 - 08:01 PM

love that term....the political correct police...made me laugh anyway

pc has nothing to do with it...im not telling you to not do it, but its obvious that there are many out there that are clueless to the dpf system...im just giving some, and i mean, some..of the true facts.


i dont blame anybody for removing the system, it isnt fit for purpose in that the life cycle is far too short even when used as was intended, let alone when driver is unaware of the importance to follow certain guidelines, let alone the sheer costy of keeping the system intact and working.


my bug bear is with anybody that promises its ok to do, without consequence..only possible loser in that outcome is the owner that deletes believing their troubles are over.


i also have issue with the controlling bodies, the ones who have been fully aware of the practice yet doing nothing to get it stopped, now its the car owners that could pay the price, not the firms making money out of an illegal practice.


if youve had a delete, and manage to carry on getting away with it, good luck to you, i drive a diesel myself, has never had a dpf so not passing judgement on anyone thats had them removed...i knew of the systems and i knew they were best avoided...im looking to buy another van later in the year, no 1 priority for me is it will be petrol, no longer interested in any kind of diesel as regs will get tougher...be they old or new vehicles

ive already had a perfectly good van that was worth £2/3k turned into scrap value overnight, without any compensation due to london lez regulations, they wont catch me out again.


know the facts, then and only then can you make an informed decision...pc my **** :lol:

#331002 New Mot Requirements ( Dpf And/or Catalysts )

Posted by wase16ll on 09 February 2014 - 11:19 PM

roadside emmission tests have been happening in london for quite a while, long before the february rule changes, both cars and goods vehicles,

as for the DPF only need to be working at colder engine temperatures, sorry, thats wrong, particulate matter is released by diesel burners throughout the temperature range, the reason they block quicker on engines that do short journeys is because the DPF doesnt get hot enough to burn off the residue...but the fact is, when engine is cold, they still prevent the PM  from being released to atmosphere.

the catalyst is also required to work throughout the range, but its important that the system comes into full swing as quickly as possible..hence the need for heated oxygen sensors, to speed up the process where the catalytic can cope with emissions.


in both cases, you will get an accurate readout on emissions with a hot engine, not a cold one


people offering DPF deletes and promising no problems with passing mot's when done, are living on borrowed time...if anyone goes ahead anyway, then strongly suggest they ask them to back up those promises in writing,  in other words, let them put their money where their mouth is.

#328420 Mk1 1.6 Focus Flat Spot

ignore what i said here "fuel trim will help to diagnose why the co is high"

although that is true, its not what i meant to say regarding your particular problem.


the fuel trim will help you see what your 02 sensors are actually doing, ie..telling the ecu wether to increase/decrease the fuel, so therefore you can work out if engine is sucking air or overfueling as well as view how well the o2 sensors are actually switching.


in my opinion, trims are one of the biggest aids in diagnosing in live data

Posted by wase16ll on 01 February 2014 - 05:24 PM

in laymens terms, fuel trim will help to diagnose why the co is high, its the 02 sensors that mainly govern the trim readings.

you may have read this already, but this is one of the better explanations ive seen about trims



#327738 Any Welders Out There?

Posted by wase16ll on 31 January 2014 - 01:00 AM

not easy to quote on welding.

in order for a good weld, you need clean metal around the corrosion, so what looks like a 2" diameter hole, can rapidly turn into something much larger in search of sound metalwork.

£2-300 seems a reasonable quote

#315833 Mk1.5 Focus Will Not Rev When Warm

Posted by wase16ll on 29 December 2013 - 08:21 PM

i wouldnt discount anything at this stage, youve got nothing so far to prove its fueling beyond the problem seemingly appearing at low fuel...maybe coincidental red herring... though its the obvious area to thoroughly check.


also may not be pump failing at all, you need to first confirm pressure is dropping at the time of the problem, if it is, then need to look into why, could just as easily be the filter on the pump blocking due to debris in tank, or possibly failing regulator.


in other words, putting a replacement pump in now, would be a gamble as you have nothing to prove its failing...could still turn out to be totally unrelated to fueling

hope its sorted, but a strange set of symptoms for a bad sensor...

#310841 Mk1.5 Focus Will Not Rev When Warm

Posted by wase16ll on 11 December 2013 - 02:43 PM

very unusual symptoms of just a bad 02 srensor (though suggestion earlier you found split in vacuum hose too, so the combined might give something like your experiencing)


be interested to know if this has cured all the problems, not easy diagnosing over www, can only be suggestions...but those symptoms you originally typed scream a blockage in exhaust, a blockage will damage 02 sensors so i would take this for a long test run because if it does turn out to be a blockage, you could ruin the new sensor if not dealt with sooner rather than later.

Easy to test for
All you need to do is remove the front sensor, keep the electrics connected and tie it up out of harm's way...
Way I would do it, is loosen the sensor then just nip it back up...take for run till symptoms develop, when still hot taking the necessary precautions, remove the sensor but keep it plugged in, tie it out the way and run again, if power returns you have a blocked exhaust.

Be warned though, doing this makes exhaust a tad noisy :)

#310646 New Rules On Dpf Removal Starting Feb 2014

Posted by wase16ll on 10 December 2013 - 10:20 PM

it is a bit harsh on all that have them removed, wether knowingly or unknowingly..but since when has the government ever worried about the little guy.


as said, new regulations in london rendered my perfectly good van worthless overnight..and also forced me to splash out for later compliable vehicle...yet the car version of my van that was identical beyond having extra windows and seats didnt fall under the regulation at all...how does that make sense???

so dont bank on any leeway being given


if your having problems with it, then your in a tough spot as removal may very well see you forking out a lot of money to replace in the future...has it been diagnosed yet, or have you tried regen yourself yet

when you say eml never been on/no codes...take it you mean codes have been checked anyway...as not all codes will trigger the eml.....


although you have no rattle in the cats, you still might have a blockage somewhere, may be worth checking, if you can get hold of a back pressure tester it would be the quickest way to test for it, otherwise maybe remove an access port in the manifold if you have one or  the front sensor (keep the wiring connected for test) and give it a run see if you have any improvement....oh and some ear muffs :)



i have no idea why the font changed itself and back again whilst writing that?????????

#309678 New Rules On Dpf Removal Starting Feb 2014

Posted by wase16ll on 07 December 2013 - 07:08 PM

it IS happening from next February, what is in doubt is how far that test will go at that time....

VOSA will have been working on this for, at the least, weeks before the public got wind of it...i have no doubt there are a number of testers out there that have been given a heads up via the regular visits they get from VOSA reps, but untill the i's have been dotted and the t's crossed, no one is in the know.

if the procedure had already been decided, testers will already have all been notified via the MOT computerised network and the VOSA site updated the moment the announcment was made public.

VOSA quite clearly states on their site that updates on this new legislation will be forthcoming.


you can also expect that procedure to be changed/adapted as time goes on...like i said, chances are that garages will need to equip themselves which will always be given time to do so within an extended period...so chances are, the initial test in Feb wont go much beyond visual, its the following months you really need to watch out for.


this is not only a uk government/vosa drive, there will be increasing pressure fom many other powerful bodies to really tighten loopholes...including europe, health depts in all their guises and the car manufacturers themselves.


knowing VOSA as i do, i wouldnt be in the least bit suprised if they leave a gaping hole big enough for a supertanker to sail through...but that pressure might make a big difference this time especially as i said, they are about to become merged into a very powerful body.

#309482 Dpf Removal To Fail Mot In February 2014

Posted by wase16ll on 06 December 2013 - 11:32 PM

sorry, thats gone right over my head???


20yrs ago it was common for belts to need chanking at 30/40k...car tax was same for all vehicles...cant remember the cost of tax but belt replacement only got expensive if they broke



today...belts commonly do 100k plus, tax is variable based on emmissions...dpf is cheap because of low emmissions...take the dpf out it will be ranked much higher.


think you misunderstood what i was saying...im liking the lack of important information at point of sale in the need for

1/ timing belt maintenence 20 yrs ago

2/DPF maintenence present day


both of which result in huge costs when neglected,  that offset a lot of savings at point of sale....

#309436 New Rules On Dpf Removal Starting Feb 2014

Posted by wase16ll on 06 December 2013 - 09:53 PM

why i would never buy a car with dpf system.....it will improve but no help to those already out there.


im not a betting man, but i reckon all angles will be covered by vosa sooner or later.


similar thing was planned for cats on petrol, but the introduction of the after cat sensor more or less stopped the mass numbers of people removing the innards of the cat.

#309423 New Rules On Dpf Removal Starting Feb 2014

Posted by wase16ll on 06 December 2013 - 09:24 PM

be warned...this may very well extend beyond plain visual check either when it comes in or adapted later.


this could also include operation of warning light, and in time, may very well include actual access to diagnostics which will show dpf is deleted.


wouldnt take it for granted its a simple visual check just yet as its vosa that decides test procedures not the government..if vosa decides a visual is all thats needed initially, wont be long before pressure makes them change it to something more stringent
