New mot rules

[bode5997]

Took my freelander for the mot yesterday,low and behold,it failed on emissions
So now have a car that is now useless,it will cost almost half of what the cars worth to fix it.Now have a very nice driveway ornament,and my next move is.............I am open to suggestions.

Is it a diesel and I guess it showed visible emissions. The car mags predicted the new tests would quickly start to hit diesels which emitted visible emissions. Its hard to really advice as it’s often the case that work on older cars quickly shows itself to be non economic You could try contacting a diesel diagnostic specialist like the Bosch specialists as they might be able to advise a solution using recon injectors and any other parts that may need changing. But if it’s cylinder wear then that’s a more costly outcome.
If it can’t be economically repaired then it’s value is scrap which is little help towards a replacement.

What year and mileage?
What’s your average journey duration?
What were the emission readings?

2012 model,just put up 78,450 on the clock,it was visible smoke,and they ended it there and then,saying no point in going any further Untill we decided what to do.The garage has said it will need work to put it right before they carry on!!!!!!!

My Quashqai 2014 plate with 40,000 on the clock went through the test three weeks ago before the new mot came in but at 30,000 I had to have the PDF filter regenerated because the previous owner just chugged round the back lanes of Norfolk, there will be more aged diesels failing on emissions and next year I will be having a pre mot emission check done, by the way my regen of the PDF cost £200.00,

 

[otherclive]

Is it in standard spec or been chipped, or dpf still installed? Did you see the test smoke for yourself and is it filmed as otherwise it could be a money spinner for garages.
Was the smoke as they started to increase the revs or was it after revs had stabilised? Sorry for the list of questions but “visible’ smoke seems a bit subjective unless what they are saying is whatever is done to the engine no visible smoke must be seen. Frightening.

 

[Dustydog]

It’s always worth taking the car for a high revving ten mile bash to get some real heat into everything.
If after that you still some form of smoke sadly there is a problem. If not things may be brighter for. Also try a different mot centre. The one who failed you. Are they your regular?

 

[bode5997]

When engine was revved and then dropped on the throttle you could see a haze of smoke,I saw it myself and thought ffs,it's not just a regen,the system is not working the way it was,the old mot you could get away with it,not now.To pass the system may need replacing,I'm not going to book it elsewhere,no point,as the guy in the garage said,if they pass it,it will come back on them,I've used this garage for 30 years,so they ain't pulling one,it's my uncles garage.

 

[Dustydog]

That’s good. At least you are not being cheated. I’d follow Clive’s suggestion and have a chat with a diesel specialist. My exhaust gas recirculating valve caused a similar problem a few years ago. Cost circa £300 to fix. Still running well.

 

[otherclive]

It must be incredibly difficult to diagnose the source of smoke. With a car with dpf at least the dpf should catch it. But in your case that didn’t happen. What do the garage say requires replacing as given yours is a 2012 Freelander with about average mileage half its value must be around 4-5k.

Changing the air filter, can help otherwise sump mist will be getting drawn into the air inlet. How long before the MOT was the last service done. ?

 

[otherclive]

I know it’s no help in this situation but my kids and wife are forever on at me because I regularly fill up with ultimate or v power. It’s not for any better performance but those fuels have a larger detergent load, and most importantly for dpf diesels have about half the ash content of regular branded diesel. So you regenerate less and create less ash residue which extends dpf life. The last time I used supermarket fuel was in the company car 2000/2003!

 

[camel]

agree with Dusty a blow out before the mot is a good idea , my mate works partime for garage taking cars for mot's and does exactly that to help clear the DPF, infact since my problem I had DPF additive ever three month or so, of coursr on the advice of my main dealer

I do the same and try to avoid supermarket fuel.

This is still a bit of a grey area as far as test examiners are concerned,on the one hand the manual says any visible smoke is a fail,yet the criteria for your 2012 car is still allowed a smoke meter reading of upto 1.5.
So what to do?these new rules were supposed to clear up any grey areas,but we're finding it a joke,even the latest cars(after 2014)have a limit of 0.7. So the rules state you can have some smoke?who knows.I know this doesn't really help,but I'd have a word and see if they'll retest it after you've given it a damn good thrash down the bypass.
Most cars will try to regenerate the dpf every 120 miles or so,if you only pootle about,give your car a good run every weekend,just a good blast every now and then will do the trick.A garage can usually do a forced regen with the use of laptop,all this does is sets the revs at about 2500rpm for 20mins ish,job done.(these are generalisation).

When crude oil is refined and turned into many different kinds of fuels and commodities you would think that at this stage they could clean up Diesel fuel and take all the rubbish out of it and then go and pick on Tut-Tutt's,

Here’s the MoT test guidance.

Being a hydrocarbon the “rubbish” that would be removed is carbon. Then it wouldn’t really be a hydrocarbon. But if it was refined as you suggest you might finish up with hydrogen. Very clean.

PS edit used spark ignition criteria in error. Apologies

Yes I’m error I described the spark ignition requirements. My sons panicking now as he’s got a 2008 FL2 and whilst it’s only got around 60k on the clock it’s due its big 10 year service which isn’t cheap. And the thought it might emit visible smoke has got sufficiently worried that he’s looking a petrol Range Rover on Autotrader. I told him frying pan and fire!

My phone and IPad have been continually reloading PC Forum pages all day. Could be a problem with PC server.

Fully serviced by me 2 weeks ago,car was up to working temp for the mot,you may find that garages will be jittery for a while Untill they find out what they can and cannot get away with.Im keeping my options open at the moment,my uncle has contacted people in the trade to see what to do next.He had a car fail it on the second day of the new rules!!!!

The rules seem quite specific regarding operating temperature and the time required at revs to allow soot ‘blow through’. Where subjectivity comes in is the ‘no visible’ criteria for dpf engines. Yet on the section using the smoke meter the vehicle can be subjected to a number of cycles to ascertain a reading.
Please keep the dialogue going as the impact on diesel owners could be significant. An Outlander PHEV may become the car of choice.

 

[bode5997]

The new rules state "any smoke of any colour is a fail"!You could just about see a haze,but you could see it.
