Remap 325d n57 204hp. What should I do with the EGR?

325d · 02-16-2015, 04:53 PM

Hi.
I have a 2011 325d (n57 - 204hp) which will get a remap soon.
The tuner say I can choose if I want to delete the EGR (software) or keep it functioning.
What should I do?

If I choose to delete the EGR (software), should I block off the system too (hardware)? I see the US-guys with 335d's recomend doing this because risk of egr-cooler pipe cracking. Will this be the same on my 325d?

Any drawbacks with deleting EGR? Will getting heat in the engine/car take much longer on really cold days?

Thanks.

A great question! I'm not sure what the answer is.

I have a 330d with the N57 and information on remapping and any form of tuning really is scarce.

Maybe email a few reputable tuners and get their take on things?

Yes disable it, I have had this done with my remap and you don't need to do anything else

Did you just have it removed from the software; no blanking plates etc were fitted?

What effects have you seen as a result?

Yes that's right just removed from software nothing else, can't notice a difference maybe slightly takes longer to warm up I read can sometimes be the case but not noticed anything
