Rewulf Posted May 30, 2018 Report Share Posted May 30, 2018 I feel sorry for the people who have removed their DPFs and had a remap to accommodate , as its an instant fail, whether its smoking or not. Quote Link to comment Share on other sites More sharing options...

Your average mot tester wouldn't know either way so I wouldn't be too worried about it. Quote Link to comment Share on other sites More sharing options...

It will come up on the computer the car should have a dpf, so the tester is then looking for visible smoke ,which would fail it, as he visually checks the exhaust he will notice whether or not it has one,they are usually quite obvious!

Vince Green Posted May 31, 2018 Report Share Posted May 31, 2018 This might work if every tester knows the rules and enforces them in the same way. However, I still remember my mate took his 1960 BSA Bantam for an MOT a few years back and had it fail because it didn't have indicators.

Most vehicles that have had their dpf removed leave the casing there and with additives I could get nearly any diesel vehicle to pass a smoke test.

Some DPFs you can smash the ceramic out and get away with not altering the casing, a lot of them are simply removed, and replaced with a similar sized pipe or box. Others are cut open and welded back up, after having the innards removed, and no amount of additives are going to bring the ppms down to virtually nothing. I would read the link above to what the new regs say, any evidence of tampering = fail. Quote Link to comment Share on other sites More sharing options...
norfolk dumpling Posted June 4, 2018 Report Share Posted June 4, 2018 What above clearly shows is we haven't got a clue (nor does Government) about the rules now or going forward. However as someone who has just dumped two diesel cars for petrol I noticed an article about work done by Bosch which will reduce diesel emissions by nearly two thirds - this is an engineered fix which not only slashed emissions but also improved MPG and BHP. In another article it appears VW have a similar fix - possibly the same - and this may mean the 400,000 cars sitting in the USA (fiddle buy-back) can be brought back and sold.
