EGR Delete - worth it or not?

[gmaz]

I have the option of having an EGR Delete at the same time as a remap. Is the benefit worth it or should I keep the non-remapped bits as standard as possible?

I've heard that the EGR is occasionally is useful in that the engine requires less than the 20% oxygen in the air, under certain circumstances or is it there just to satisfy regulations

You are legally only allowed to delete your EGR if you've never complained about VW "cheating" there emissions results on an online forum.............. ;-)

No don''t delete it. Buy a faster car and stop pumping diesel st into the atmosphere.

Is it a requirement to have an EGR fitted if it came out of the factory with one?

I think that legally the DPF cannot be removed, but that doesn't apply to the EGR?

Oh of course, doh, that's what I meant.

I reckon you can do what you like with the EGR system.

When I had my 320d remapped I declined the EGR delete because it does serve a purpose/function and If its working correctly then why remove it.

Not sure if it's the same on your specific vehicle but some cars can smoke a lot more without a EGR and all that soot is going straight into someone's lungs. I do a lot of miles and you can always tell which car has had EGR deleted as they absolute stink if your following along with huge clouds of ste.

Haven't noticed any more smoke than usual out the back post mapping.

Hi!
I'm a new guy in this forum but anyway.. Is it possible that too much engine oil could cause problems with the EGR system? The dipstick has now atm got oil a little over the MAX level.
The Emission Workshop light on the dashboard went on. Then I cleaned the EGR. After that, I went driving again and after approx. 4 km the Emission Workshop light went off in the same way. Is there too much engine oil?
Thanks for helping!

Why does nobody like using the word "remove" anymore? "Delete" sounds utterly pathetic. You don't delete an EGR valve, you remove it.

Because its often 'deleted' from the software to prevent it from opening. And not removed. So 'Removal' would be an incorrect term.

Most of the time it's removed and blanked off.

Do you guys have any thoughts and ideas about my question?

Do it, they will eventually fail anyway and are expensive to replace. If you can blank it off your car will thank you for it.

Where's the excess oil coming from? Could well be that the sump's being filled with unburnt diesel after failed DPF regeneration attempts.

Are they checked for the MOT? Or is it part of planned changes to check for anything not factory?

I think i poured in too much oil last time i filled it.

IMO it's because people mistakenly believe it makes them sound knowledgeable.

Very occasionally EGR operation is disabled (neither deleted nor removed) via the ECU, but usually the valve is either removed entirely or retained and a thin blanking plate fitted to prevent it passing any exhaust gas. Nothing has been deleted.

Hope it's not raining this weekend, I plan to do a dirt delete on my car.
