Thanks for that Paul, and for posting it on the GLASS forum, it's such a small world this off road one :D .

I'm a bit confused by your comment about they only thrash the diesels once.

Following the meter prompts, depress the accelerator pedal quickly and
continuously but not violently, to reach full fuel position in less than 1
second, hold it there until a release prompt is given, then immediately
release the pedal. Allow the engine, and any turbocharger fitted, to
return to idle speed.

Surely that paragraph and the following ones suggest they can thrash the balls off it up to six times.

Anyway, no mention of a 4000 rpm requirement so I wonder where the testers got that from?

Ho Hum.

You only go to full fuel position on the first test and that is only done the once.

If it passes after the first opperation you then move onto "Method of Inspection 3" a visual check.

Don't know, Sounds like he needs to read his testers manual. :lol:

hobbit:
A lot of testers dont agree with the revving of a diesel and looking for bits underneath afterwards, but they have to follow the rules set, sometime in the future I imagine the tests will change, but god knows when, until them, all you can do is stick your fingers in your ears and pray

Is a reading of 0.92 K(1/m) good for a diesel engine?
