Has anyone done, or know of anyone that has done a full EGR delete on a V10 tdi?

I removed the pipes connecting the exhaust manifold to the EGR valves and fitted blanking plates over the holes. No faults etc came up as the pre-DPF V10 engine did not monitor the exhaust gas flow.
You cannot do it to the DPF engine without a software fix as well as the system detects a lack of flow thru the DPF and a fault comes in the dash.

Mine is a 2003 model so that should work. Where did you get the blanks from? I may see if someone can fabricate a pair of delete pipes. I'd like to get rid of the coolers too.
Thanks for the reply though,much appreciated.

I made the S/S blanks myself. In fact I may have a few laying around as the exhaust end is a different size to the EGR valve end.
I will look some time soon and PM you if you want.
You don't need any pipes just the blanking plates.
What coolers are you talking about the Pre DPF has no EGR cooler ?

After installing blocker plates... Do you think the blocker plates for a 2.5 tdi egr delete will fit for the v10 tdi but needing total of 4 blocker plates.

So, do I need to do anything to my software in my 2004 R5?
My EGR is blanked, I get no engine warning light and I do have an EGR cooler.

if u dont mind me asking "and im sure u all mind me asking" what are u after. under full load egr is turned off and at cruise egr is at its highest command. u will use more fuel and have higher egts without egr. the only real draw back is plugging up the intake.

It seems to me that preventing or removing a cause of intake plugging is enough all by itself. The whole purpose of putting exhaust gasses back into the combustion process is to reduce peak burn temps (not necessarily exhaust temps). Limiting peak temps limits NOx formation - it also lessens the total amount of heat available to do work. Work is the basic reason for the engine to exist. No engineer worth a darn will build a bigger engine that necessary and then voluntarily 'de-tune' it down to something smaller. Goes against the grain! NOTHING about the EGR system produces more work than if it weren't there in the first place.

My R5 was using coolant at the rate of 3 litres per 1000kms.
The first thing I did was block off the EGR cooler and subsequently the EGR itself so that the intake didn't get super heated air.

The coolant problem was the water pump but I've left the EGR blocked because Pikanini says that it reduces intake blockage.
