EGR delete on 1.6 TDI

I am pondering about an EGR delete for my 1.6 TDI. For fe reasons but mainly because I do not want to deal with the intake gunking up.

Also I need that port to do water injection without drilling the manifold etc.

The car has cooled EGR and I do not want to lose that benefitaswll.

I have a good tuner that can probably delete the egr and make all the software corrections.

Now how to retain the warmup effect, if i just vent the end of the egr next to the exhaust would that be the same as running a mini straight pipe? Plus I can have the EGR on absolutely full untill engine warms up.

How much do you hate your neighbors that you are going to purposely disable pollution controls to save a buck?

My last TDI didn't need the intake cleaned until 200K miles.

Those pollution controls on that vehicle use more fuel, produce more soot and only lower NOx when working correctly.
It's only bad if you have NOx as your primary air bore pollutant.
Then as time goes on your intake gets plugged up with soot mixed with pcv gunk which further increases soot production, further lowering fuel economy and actually increases NOx.
The diesel over there isn't as clean burning as European and US diesel.

I deleted the EGR on my diesel suburban back around 2006. It smoked way less with out it and I cleaned the soot oil dirt gunk out of the intake at the same time. Deleting the EGR was and cleaning the intake was like putting s new engine in it.

I will be having water and steam injection that serves as a better means of NOx reduction without the nasty side effects.
