Disabling EGR

[Kaurinho]

Yes but I can't do it with my own hands.. Thought of something like OM646 few resistors,diode...

 

[Kev555]

Not sure about that bit

 

[oigle]

Remap is best way. Could get a performance upgrade at same time

 

[Kaurinho]

Ok. Thanks will do some checking out where I could drive to

If you're in the UK be aware EGR operation (along with DPF) is likely to become an MOT testable item with automatic fail if it's not functioning.

 

[Kaurinho]

Thanks for advice but I am in Germany Tüv may see it too. Some of buddies say they can't they did it before but was now at mechanic and he said yes they can see it

On the OM642 engine it's definitely possible to monitor the operation of the EGR using live data. I'd be surprised if yours was any different.

It's too late in the day for this to become real with diesel and petrol being outed .

Should of happened 15 years ago .

Always fake noise from DVSA / Matters of testing , etc .


The obd equipment will have to be reliable time and time again , it won't be reliable and will revert to the default test of diesel smoke opacity of which will be OK as a disabled egr causes more complete fuel molecule combustion thus less particulate matter .

So glad we have a representative from the VOSA/DVSA MOT testing policy department to reassure us all that it won't be tested...

It's an 11.5 year old thread , that must tell you something .

 

[LostKiwi]

It just tells me they haven't got around to it yet however there is more focus on emissions now than at any time in the past.

If they can get diesel and petrol cars off the road they will.

 

[Kaurinho]

Thank you for your replies. I appreciate it much

I do often think that the EGR/NOx levels will be measured during future MOTs, however it would require all MOT testing stations to have rolling roads, and I cannot see that being feasible. At idle, the EGR isn't used, only on partial throttle, so they'd need to be tested on a RR or with expensive equipment that hooks up to your car as the MOT driver takes your car for a spin...

Having said that, I vaguely remember reading somewhere that they do it in the USA? Anyone able to clarify?

Testers do now have a dongle to plug into the ODB which doing an emissions test, essentially to verify that the probe is actually inserted into the vehicle they are resting, it also checks certain functions of the emissions system are sending/receiving signals. I’m not sure how much data is there but suspect it’s only going to get more integrated with the test.

 

[Kaurinho]

Yes but you can't expect that 7-10 year old car works as fine as new one. There must be tolerance in between the values should be. And I am pretty sure without EGR gases may be even cleaner after long time as complete induction system stays clean whole time, because dirty intake will make unefficient combustion and cause many other problems

 

[LostKiwi]

Sadly that makes no difference to legality.

 

[Kaurinho]

Nope but makes sense. If they look blindly just gases they can't see it anyway

 

[V6Matty]

There will be very little tolerance I suspect if the car is maintained correctly, that also won’t get around if it’s been bypassed and the software being out of spec

If the Government go down the road of forcing polluting diesels and petrol's off the road would they not take the cheapest option like taxation rather than more stringent testing of emission equipment. I dont have a clue how the government works in conjunction with MOT centres in England, Scotland and Wales. Do they receive any funding etc from Government? or purely private enterprises with government oversight?
