The MOT test changed on 20 May 2018, with stricter rules for emissions from diesel cars with a diesel particulate filter (DPF).
Your vehicle will get a major fault if the MOT tester:
- can see smoke of any colour coming from the exhaust
- finds evidence that the DPF has been tampered with
These new rules, say BG-GB, mean ‘cheat’ options such as isolating or removing the DPF have no place any longer – so any issues with the diesel exhaust system must be tackled properly.
BG Products spent 4 years looking at the problem of blocked DPFs and their conclusion is that cleaning a DPF in isolation will only defer the problem, not cure it. It is for that reason that BG Products developed their own unique system to clean DPFs AND restore engine combustion efficiency, thus prolonging DPF life AND restoring economy.
BG’s Complete DPF and Emissions System Service cleans right from the air intake, through the engine to the DPF. The decarbonisation process, which cleans the air intake, injectors, piston rings and DPF has been put to the test by Frank Massey (see below). The pre-test measure of approx. 800mbar of DPF pressure in the test vehicle was reduced to 100mbar by the Service, “an incredible result” according to Frank.
Other options only tackle the symptom of the blocked DPF itself. BG’s DPF & Emissions Cleaning System attacks the real problem - poor combustion and the consequence, soot build-up.
