My turbo Diesel is of 2005 vintage.
I'm sure on the emissions test that the smoke limit was 3.0 until the last year or two but it's now on a test limit of 1.20.

Isn't the pre 2008 limit 3.0 for turboDiesels, or was that revised downwards.

Would especially welcome the definitive answer from an MOT tester if one happens to be reading this, it failed first time, just over the 1.20 but a can of injector cleaner sorted it easily (also probably needs the EGR and intake cleaning out, job for summer), just wondering if my garage are inputting the wrong test figure or would that come up automatically on the system when they input the reg.

There is a thread which a few MOT testers frequent to answer such questions
