Hi,

I've had an idea, Not sure if it would work :confused:

IIRC there are new rules for lorry's and trucks to be Euro V compliant to travel into the city of London, think its called the Low emmisions rule or something like that,

my question is, can you remap a vehicle to lower its emmisions?? Well in my case a 7.5 tonne lorry??

Any ideas welcome??

Probably not - the 'powers that be' go on the manufacturers stats.

I've recently been thinking of it from the other way though - could I buy a Greenline Skoda, then get it remapped to make it half decent, but keep the £35 tax?

I know you can get trucks remapped, just the same as a car etc..

But unsure on if it would lower any emmisions.

Even if it did lower them, do they not just go by the manufacture rating, rather than individual vehicles ?

People definitely do get their trucks remapped. Big improvements in torque and economy can be achieved. However, I don't think its possible to get a car's C02 re-graded, so I'm sure the same applies to lorries.

However, I do know theres big business in converting lorries to be Euro V compliant... so who knows.

I haven't looked into it in great detail, so correct me if I'm wrong, I think you take the vehicle to VOSA and they'll retest it and go from there.

The problem is they charge you £200.00 each and every time you go into London in the low emmisions zone!

I'm getting quotes for convertions but @ £3-4k +vat :eek: it's cheaper in the short term to run into the zone for £200.00 in this financially economic time.

AFAICS this country is too stupid or too lax to bother with tweaking the paperwork of a vehicle unless you put a different engine in it, paint it or cut it in half and call it a bicycle.

I think that unless it's a type approved Euro ?? compliant vehicle, you're stuffed.

J.

I take it your truck is euro 4 at the moment? Im pretty sure you wont get euro 5 with a remap.

Emission Standards: Europe: Heavy-Duty Diesel Truck and Bus Engines

as you can see the only reduction required is NOx, which just so happens to be one of the hardest things to reduce, hence why you now see lorries with an extra tank with a blue cap that contains urea for the engines SCR (selective catalytic reduction) system. Some companies have gone the EGR route, but as far as i know nobody has achieved it by just remapping an euro 4 engine.

I watched a programme the other day about the BMW diesel engine with one of them, also a particulate filter that limits the black smoke from the unburnt diesel through the exhaust!

I'll be honest, I don't know much about the current engine in the truck, but I assume the EGR route is what we're being quoted big money on!

I've spoken to our local truck garage and they say that it may not even need one, they're going to check the emmisions and possibly change the ECU settings which they can do apparently!

Road tax is based on manufacturers figures and can't be changed retrospectively. Mr Taxman would have to inspect every car to make sure your claims were valid, and it wouldn't do to have them work for their (our) money..

I think that kitcars and the like might have the pre-2001 scale (+/- 1549cc) applied regardless of emissions, but I'm not sure if that applies for cars where a significant amount of the build comes from one donor vehicle.

For the OP, you can have a wagon engine modified to make it LEZ compliant; I suggest you buy T&D or Trucking, and look at the adverts for more info.

Ref the remapping a greenmotion or whatever it's called; no problems with losing the low road tax. These are the people who came up with the idea that my Xantia TDi should pay 1.5x the road tax of my sis's Micra, despite it using less fuel!

I have noticed in the past that one of the site sponsors - Derv Doctor - does truck remaps.

Might be worth having a chat with them about what is possible or not.

What sort of truck do you have? how old is it ? and is it a euro 3 vehicle? I work for a Daf , M.A.N. and Iveco dealership and might be able to get you the info needed.

Thanx for all your replies guys,

Took the M.A.N. to the local garage that used to service it, (I say used to because they were a little expensive and didn't actually sort the trucks out for HGV MOT) they tested the emmisions.

The result I didn't really understand, but what I did understand, the limit is 0.4 (of something) for being LEZ compliant in London, our truck was running 0.2, and some help in the aid of an engine additive would lower it further.

The garage is not VOSA approved so have booked into a VOSA testing station to get a LEC (low emmisions certificate) this tuesday coming!

As the MOT isn't due til Oct'09 its costing £29 rather than £17 which is the usual price if the test is done at the same time. :thumbdwn:

But on the up side, pending a pass of the test, we can use the vehicle to go to London and not pay for it , (apart from the congestion charge of course )

700 quid powerchips(or something like that)too one of our trucks from 580bhp up to 710bhp ,my current r420 scania is chipped up to 500bhp,its very common and makes a big difference to both power and mpg,mine now averages 7.2mpg post map and was only doing 6.3 before

Oh dear, got the truck tested at VOSA, they've said that M.A.N didn't register any of their engines with TfL for some reason or other and that means our engine is not registered as Euro II and because of that TfL will NOT let us use it in the LEZ! :mad:

Aparently, even if the vehicle is just blowing pure air out, it still wouldn't be allowed as M.A.N. hasn't registered it!

Not a happy bunny, just as I thought I were getting somewhere and sticking to the man, then powers that be have kicked me right back down again!

Anyway, I am determined to get it sorted, Anybody know of someone that does 'Particulate/particular filters' for the exhaust??

Any help on this would be great, and thanks to you guys that have already replied!

Got the wrong info

Try and get in touch with a Bosal exhaust specialist, or even an M.A.N. main dealer. they might be able to tell you if one is available to fit your truck
