Just seen this on IWOC:
"From the 1st of August, a new 'Basic Emissions Test' was introduced. All
cars will now go through this test, if they pass, that's it, if you don't
then a full emissions test will be carried out.
The BET limits are:
Fast Idle (2500-3000rpm):
CO no more than 0.3%, HC no more than 200 ppm, Lambda between 0.97 and 1.03
Normal Idle (450-1500rpm):
CO no more than 0.5%
If you car fails the BET and it isn't listed in the emissions database then
a non-cat test is carried out. In this test the CO can be no more than 3.5%
and the HC and be no more than 1200ppm."
Does this mean a car will now struggle to pass an MOT with a decat DP and OEM centre cat?
