How can I lower the exhaust emissions on my Land Rover Discovery for it's MOT?

The MOT is on Saturday and last year my Disco was borderline. Is there anything I can add to the fuel etc to lower the emissions? ThanksHow can I lower the exhaust emissions on my Land Rover Discovery for it's MOT?
Use a liquid injector in the tank ( Maybe 2 bottles in a disco )

change the air filter

and change the fuel filter



in extreme cases I've known injector cleaner be used directly from the fuel filter



a good cleaner is made by Wynne's



hope this helps good luck with the test
seems like a certain "mobile mechanic" doesn`t know that a Discovery is not a Jeep !How can I lower the exhaust emissions on my Land Rover Discovery for it's MOT?
Stop driving a Chelsea Tractor.
Have the injectors cleaned and a new air filter to start with.How can I lower the exhaust emissions on my Land Rover Discovery for it's MOT?
I agree, add injector cleaner and take it for a good hammering, foot hard down in third for several miles to clear the cobwebs usually does the trick - you'll see the crud flying out of the exhaust. Not a bad idea from time to time anyway, MoT or no MoT, especially if you're normally quite a gentle driver.
do you have a friend who mot's cars? if so get them to put a tea towel in the exhuast of the car during the emissons test. thats what the bloke who mot's my other halfs car does
Like Mike says and then thrash the engine to within an inch of it's life just before taking it for it's test.

And hey GRIZZ....piss off you politically correct wannabe gynocologist.
Hi



A good practice is to add one bottle of injector cleaner to half a tank of fuel (or two to a full tank), and then give the jeep a good blast up and down a dual carriageway at high revs, but not in the red, which will clean out the injectors. DON'T do as a couple of people have advised and drive it flat out foot to the boards, or as one person says, thrash it to within an inch of its life. That, as any half decent mechanic well knows, will DAMAGE THE ENGINE!!! Come on people, lets have some sensible answers, this is someones car we're talking about here and your advice could well lead to a blown head gasket or worse.



Some other little tricks to lowering the emissions are as follows:- Clean out the breathers, fit a new air filter, and if you're feeling brave you could even whip the EGR valve off and give it a good clean out to ensure it closes fully, but thats just if you're feeling up to a bit of spannering!



Good luck

yes there are a number of things that can be doneor added to the fuel system.stick with the well known brands,have 10/20 ltrs inthe tank add the stuff and go for an mot when the engine is hot.
the best way is to add FORTE fuel conditioner ,it comes in a tin for about 拢10 ,pour it in the fuel filter and let engine run for about 15 mins ,it cleans the whole fuel system and reduces emissions and excess smoke .it works 99 out of 100 times ,its magic stuff...
