Default EGR Bypass

I've just heard about new emission tests for diesels next year. I've got an EGR Bypass valve fitted. Could this cause an emissions failure on the new test? I haven't got the original EGR Valve. Might have to get one and replace it. Thanks

No, diesels are not subject to the full emission tests (HCO etc) and are only subject to a smoke test.

Yes, but the 75 is not fitted with a DPF, so the EGR removal does not affect the test. DPF's are the spawn of the devil, a poor attempt at trying to reduce soot emissions from diesels!

Hi, our cars do not have diesel particulate filters so do not come under these new rules.

cheers, Pete.

Thanks for the info. Is it only modern diesels that are fitted with DPF's or only certain makes of diesel engines? Thanks

It's part of the EU emissions regulations, so most (if not all, I'm not too sure?) modern diesels will have one. It seems to be 06 onwards that they suddenly become popular.

Hi

Just to be clear....... Are we saying that a Rover 75 cdt (03) will pass the MOT test with the "cat" removed?

Car will be tested in Northern Ireland - March 2014.

Thanks
