Diesel Filters and MOT

[Barney123]

Don't know how relevant the following is to our Motorhome tests.

 

Diesel filter check added to MOT test

 

 

The testing of diesel cars, vans and lorries is being tightened up to ensure they have a critical exhaust filter.

 

From February, garages and testing stations will be required to check for diesel particulate filters when inspecting the exhaust system as part of the MOT (or annual test for heavy vehicles). A vehicle will automatically fail if a filter has been fitted as Original Equipment but is found to no longer be present.

 

Particulate filters work by trapping solid matter from exhaust gases. They have been in use for more than two decades and help diesel vehicles to meet EU emissions standards. However they also need to be ‘regenerated’ regularly and, if not done properly, this can lead to a build up of soot, which can affect fuel economy.

 

Consequently some diesel owners opt to remove them, which makes their vehicle illegal for road use. It is an offence to drive a vehicle that has been modified this way, as it will no longer meet the standards it achieved when approved for sale in the UK initially.

 

“I am concerned that vehicles are being modified in a way that is detrimental to health and undoes the hard work car manufacturers have done to raise emissions standards,” Roads Minister Robert Goodwill said. “This change to the MOT makes it clear – if you have this filter removed you will fail the test.”

Thanks Derek, I have just woke up

Just remove them, bang them hard on the ground, shake all the bits out and refit them. As far as the MOT is concerned it is fitted!

 

Stupid law.

I think that 'two decades' is a bit of an exageration, DPF's have only been fitted for the last 5 or 6 years,

on cars and smaller commercial vehicles anyway. And a 'pain in the backside' they are. Ray

I think the o/p is confusing a catalytic converters with a dpf, which also needs some expensive liquid to be injected as well.

Don't need any expensive liquids on Fiats also only manufacture to compile with Euro 6 without addictives.

An additive may or may not be used with a DPF

I'm not sure if Fiat will meet Euro 6 emissions standards without using an additive. I know Nick Fisher has mentioned it as likely, but all I can find on-line is this truck-related article.

This says that Fiat will use a non-EGR method to meet the Euro 6 limits, but the article indicates that an additive will still be required.

Thank God i don't have this daftness to put up with on my van. However the LEZ stopped me from visiting my son in my van (Transit 2.5TDi), but i was ok in the car i had up till last month, a Focus 1.8 petrol.

 

The LEZ is supposedly all about 'emissions'.

 

No prizes for guessing which vehicle engine returned the lowest emissions on MOT!! *-)
