Dave, firstly welcome sir

Secondly, i do NOT know of anyone that has managed to blank TDV8 EGR's yet sir. They are electronic so cause all manner of faults just blanking them... They need mapping out too...

So, unless your Dad has a strange obsession with watching his money go up in almost the same amount of smoke that will come from the LH exhaust... My advice is to resolve the issue immediately sir...

Alive Tuning, for one can map out TDV8 EGRs

If you are familiar with mapping software, it's not a huge issue to overcome.
The issues lie I making sure your work is not copied by Joe Bloggs

Ok So this might be a dumb question isn't the egr on a TDV8 the same as one on a TD6? i.e. the computer tells a gizmo when its time to open the egr the gizmo sends a signal to a thing-e-mebob and the thing-e-mebob sends vacuum to the egr opening the valve into the inlet manifold

I only bring this up because on my TD6 I blocked the vacuum pipe there by stopping the burnt exhaust gasses
re entering the combustion chamber

have I done wrong ???

Bit more complex on the TDV8

The valves are electronically controlled by the engine ECU. When the valves are opened, the management is expecting to see a drop in airflow through the air flow meters, as it shuts the butterfly valves on the throttle bodies, to "suck" the waste exhaust gas through the EGR.

This is due to emissions regulations, with the TDV8 being an EU4, and the TD6 being an EU3

In addition to this, due to EU rules, EU4 engines MUST display a warning if there is an issue with the emissions control system. This was not a requirement on EU3

Cheers cobber so we have Brussels to blame again..............

Why cant they keep things simple

No. A warning light does not a complex system make. And emissions tightening standards is only sensible.

And, though advancing technology makes reducing emissions even further a possibility, the un-robust EGR system on the TDV6/8 is a JLR specialty.

(wife thinks I'm nuts - prob right, too)

On the point of blanking the EGR with plates, we have done this in a few local TDV8 3.6 without deleting the EGR duty cycle in the map, and have had no DTC come up
Perhaps the software is different between UK and ROW vehicles?

So, does mapping out the EGR valves cause emission problems at MOT time? Got - 2017 SDV8 Autobiography in Loire Blue
Had- 2008 TDV8 Vogue SE in Java black
Had - 2007 S/C in Stornoway Grey

We don't have such a thing as an MOT here in Africa
I assume that question is not for me

My D3 passed its latest MOT with no EGRs and with no Cat

Bet that smells like an old ice cream van doesn't it? Removing both the EGR & Cat makes them stink!

It doesn't smell nice

Made all the difference to the way it drives though. Even those with *highly recommended* remaps can't keep up with mine

Over to you Craig yours takes some beating

Mikey is referring to a 2.7 tdv6 Disco Scott... So no comparison to a tdv8 FF my friend...
