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

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.

I've read in LRO that putting even small quantities of petrol in a diesel
engine is a realy bad idea as it strips away the vital lubrication that the
engine requires.

Hi Paul,

Funny you have come up with this post, but have just heard the same thing
from our local MOT station, and then took to another test station and passed
there without any problems, I beleive with readings
of 2.50.

Just a thought !
Was it a new type testing station, and if so are they doing it correct !!!!

and unless it's obviously got an injector fault or something, I'd be
sceptical of replacing injectors. Presuming it's no EDC, the pump can be
adjusted. if it IS EDC, then there could be an electronics fault leading to
over-fuelling.

"trained land rover mechanic" isn't necessarily what you want, in any case.
"diesel specialist" would be what I'd hunt. If you were in west wales, I
could point you to one :)

Our local MOT place has a nice 3 mile uphill well suited to hammering up
flat-out in 3rd...

Norty boy, then, the tester: you're supposed to measure the oil temp which
should be up to a specified level before commencing the rev-the-nuts-off-it
stage.



Other tricks you can do:

move the maximum engine speed stop in a bit to lower the maximum revs by 500
or so. This makes a fair bit of difference and may be enough together with
the other things like making sure the engines properly up to temperature and
nailing it up the road just before the test.

You can't really do it wrong, it's all computer prompted. You can press the
throttle down slower when the computer tells you, this will actually reduce
the emissions considerably, but is about the only "fudge" you can do.
As for the oil temp, there have indeed been issues with ends being eaten due
to the flexibility of the probe, being inserted into a very turbulent area
of an engine, in close proximity to a whirling crank and rods, where the
original dipstick was solid or at least stiff enough to resist any flexing.
If the vehicle has been driven there immediately prior to the test and is up
to temp (i.e. it's gone at least 10-15 miles) and it's kept running right up
to the emissions test, then there's nothing to be gained by checking the oil
temp 'cos it ain't gonna get any hotter unless you work it hard! Within
reason, the temp has nothing to do with the emissions, it's simply a check
that you aren't "racing" an engine that hasn't got up to working temp for
correct lubrication. What reduces the emissions, is getting the thing hot
enough (piston crowns, injectors, valves etc) to effectively self-clean all
the accumulated soft carbon that builds up when driving sedately. The MOT
test works the engine hard enough to loosen this carbon, producing the smog
that fails the test.

P.S. Not that I need one now, but...

The machine does ask can the temp be measured?
problem is, on some vehicles the probe is too big for the dipstick tube or it's
inaccessable so as long as the temp gauge shows hot you should be ok
I can't honestly remember the last time I measured the temp before testing one
and I don't think getting it a few degrees warmer would bring the readings
down that far
