I also understand that egr tampering via blanking is a fail, hence electronic mapping. If you had seen the condition of the inlet manifold, egr mixer, swirl flaps and inlet ports to the combustion chamber, you would've had some idea that "complete combustion" would never have been achieved. The airflow in the egr mixer was constricted to roughly 1.5 inches, not its full bore of 3". The swirl flaps which were to aid combustion, improve torque, were not performing properly, all at fault of egr. Hence my reason why I decided to kill the egr. I want to get another 170k out of this d5. Going through its breathing system and remedying it's issues would bring it back to near "clean air" which I doubt a lot of pro diesel egr folk do not understand. I am certain that all the gunk and goo would be severely increasing emissions of nox due to incomplete combustion. When was the last time you cleaned your intake out? If you've done it a few times, I think you'll change your thoughts on that little valve and cooler. |

Increasing NOx emissions at least fivefold is hardly making it run cleaner.
And there's your strange claimed motivation behind this - the presence or absence of an EGR will have no bearing on engine longevity. Wear of critical components will not be influenced by an EGR. If you can't afford to maintain or repair the car properly you should just say so instead of making up specious excuses to justify your actions.

And as predicted the thread goes sideways... Its the reason why I gave up on this forum a long time ago. It used to be a nice place to be. But all I see are bitter and twisted folk who aren't able to hold a decent motorist conversation without quoting laws as if you've got the power of vosa.
My car, my choice. Far from "cheapskate thuggery", just understanding on what makes a vehicle run well and longer. If I get into trouble for disabling it, it's on me. Not for you to berate me. I was explaining my findings. |

And this is why ice vehicles are doomed, because even when the manufacturer tries to do something there's always a bodge. Always.

Shouldn't we be allowed to express an opinion about law-breaking and deliberately polluting? Quote:
Your 'findings' are generally worthless, mostly because you don't seem to understand EGR flow and the significance in reducing NOx emissions. You should have just restored the EGR valve to a functional state, perhaps by merely cleaning it for free?

Crack on. We can all put up with lower speed limits whilst people insist on doing this.

The sale of new ICE cars ceases in 2030, and people pulling this sort of stunt will get the existing ones outlawed off the road as well.
There is no coherent technical, moral or legal argument in favour of what you have done.

You'll never be given any credit from some on here for keeping an older vehicle running.
Personally, I'd have kept the freshly cleaned EGR as standard but I'll never judge anyone who is ultimately preventing an older car having to be recycled. A lot of people's idea of being environmentally aware is to have a new lower emissions car built for them every few years whilst ignoring the environmental implications of producing said car. In the 9 years I've had my one, very well maintained old car, some people have had 3 or more cars built for them yet think they are the epitome of green. Most don't even own their cars so are in a cycle guaranteed to be adding yet another newly produced vehicle to replace a perfectly usable car in a couple of years. Their green delusion would be funny if it wasn't so harmful.

In the past, before I grew a conscience and reached puberty, I have disabled EGR on a number of cars. On some old 1990's Land Rovers it used to make a slight difference to response and economy. But on any Volvo engine (D5 and 2.0D) I've tried it it makes no difference at all. EGR and DPF systems on Volvo cars (excluding perhaps the 1.6 PSA engines and wet DPF) are a very good design and on an otherwise healthy engine - don't give trouble, and have no impact on how quickly the oil gets contaminated with dirt. Whether you agree with the tightening of emissions controls on cars or not, many of the localised controls (clean air zones in London, Birmingham etc.) are a direct response to high levels of NOx emissions measured at the roadside from diesel vehicles. It's quite possible that if owners maintained their cars and didn't make illegal modifications, owners of Euro 5 vehicles wouldn't have to pay eight quid to get to work in Birmingham now. As others have said I also have a personal opinion that the OP doesn't fully understand what he is doing, the EGR valve would not be operational in a fast acceleration run as part of an emissions test on an MOT, so disabling EGR should not impact that part of the test - it is the presence or interreference with the EGR system which is examined. So don't congratulate yourself thinking you've done the world a favour - you haven't - you've done yourself a favour at everyone else's expense.
