Failed mot emissions bigtime

took my disco 300tdi for its mot today, failed on two things. one head light
beam too high, and the emissions which were-
peak 1 9.99 m-1
peak 2 9.99 m-1
peak 3 9.99 m-1
peak 4 9.99 m-1
peak 5 9.70 m-1
peak 6 7.74 m-1

average 8.95 m-1
limit 3.00 max

serviced it 1 month ago so a new air filter was fitted, took it to a local
garage who is a trained land rover mechanic. he suggested fitting new
injectors should fix it but he also said very rarely it could be the
injector pump. its going in Tuesday for new injectors, another 400 gone.

This is sometimes normal for an engine that isn't worked hard. The level is
falling, which is what you would expect to see anyway. Some of the motors we
get in for test respond well to a blast down a local back-road and back then
re-test the smog emissions. Some need a tub of injector cleaner and the same
blast, but I've yet to see one fail after that, maybe worth a try before
shelling out 400??

before I mot my diesel vehicles, I normally run couple of tanks of
injector cleaner through, coupled with some hard driving, and making
the engine work. On the way to the MOT I normally never use 5th, and
rarely 4th.

Have used this method for years, and never failed test on smoke yet...

Like what other's have said, give it a good thrash before spending
money. I've only been MOT testing for 6odd months but I've seen loads
of gently driven diesels failing as spectacularly. A 10 minutes thrash
near the red line soon cures them. Is there an oil temperature on the
read out?

no temperature is shown, infact now i think about it he did not put a
temperature probe in the dipstick. i did have to take it for a spin of
around 3 miles before he did the test

just had another look and it says oil temp verified, how he did it i do not
know, certainly did not check via dipstick

I once had horrid readings in an MOT test so went to a local motor
factors for some injector cleaner.
I explained why I wanted some and they suggested fitting a new fuel
filter and filling/priming it with 'some of this' dunno what it was,
some kind of injector cleaner, IIRC silver bottle with blue or green
lid, smelt and felt like diesel but twas a funny colour and also
'chemical' smelling.
anyway I did that in the car park there and then, blasted it the 10
miles to the MOT place near home for a retest.
He said something like 'clucking bell'.
worked a treat anyway and was very very interested to see what I'd
used on it, the other guys all came over to see too.

Chucking a couple of gallons of petrol in worked for me. Refill with diesel
after.

On our machine, if you ignore the prompt to measure the temp for 40
seconds it'll carry on without it. I know some people don't like using
the dipstick probe thing as there are various storys circulating of
the end being eaten by the engine.

I'd take it back, get it done properly or go somewhere else.
