Emissions aren't tested on diesels .... Emissions are just for petrols ....
Metered Smoke Test (Diesel)
The metered smoke test has been conducted in
EU countries for many years. During this test, a
calibrated smoke meter is used to assess the
density of the smoke from compression ignition
(diesel) engined vehicles.
The engine will be accelerated up to governed
speed and the smoke density measured.
Engines that emit very little smoke and achieve
a meter reading of 1.5m-1 or less will pass the
test after the first acceleration. However, if the
test is not passed on the first acceleration a
further two accelerations will be carried out.
The average of the three acceleration readings
will be calculated and if the reading is at or
below 2.5m-1 for non-turbocharged engines
or 3.0m-1 for turbocharged engines, the
vehicle will pass this element of the test.
However, if the average is higher, a further
acceleration will be carried out, and the average
of the last three readings will be calculated. This
will continue up to a maximum of six
accelerations. If the average of the fourth, fifth
and sixth accelerations is higher than the
appropriate level, the vehicle will not pass the
test.

This bit might worry the SDi guys ......
In addition, vehicles may be refused a
certificate if the exhaust emits excessive smoke
or vapour, to an extent likely to obscure vision
Just get you cars MOTd in March guys .....
