Mine takes considerably longer to get up to temperature with EGR mapped-out than before even in the middle of summer here, so in cold climates you might be waiting a long time.

Mine hasn't changed in time to get up to temp and it was -7c here on Tuesday morning... Cam

Old thread ressurection time ,
Those of you that have been running with an egr delete for some time now have they caused any issues ?

Yes it has; a much cleaner intake and improved mpg and response  Cam

very pleased that I got my EGR programmed out, this was done when it was re-mapped using a mobile technician that I have used before, he trusts Alientech equipment to do this on JLR vehicles and many others

On my TDV8 4.4 he had to remove the ECU ( lifted it out of the battery compartment area ) , easily done and 45 mins later it was taken on test drive and did seem to have a bit more - but hard to quantify to be honest

its now nearly coming up for 5 years, and am still pretty pleased that I got it done, by the way, you don't need to cut out your DPF ( you should not do it anyway re new MOT rules ) BECAUSE the EGR being programmed out ( soft delete ) is all you need

NB you may want to use Launch UK every 10,000 miles to help clean the DPF from time to time

If the EGR is removed from the equation will the DPF still be functional or useful?
I tried doing things the right way and the EGR temp sensor nut snapped off, so has left me in the situation of an engine out repair or disable the EGR and remove DPF?

my car has been exceptional - so yes of course it will be OK with EGR programmed out, and leave the DPF in situ please - no need to take the engine out, you don't need the EGR sensor or anything EGR related once it is programmed out !

Yes it will cost you £200 or so to find someone who can program out the EGR from your ECU, but that it a much bettter place to be than pulling an engine !

That was my train of thought.. Disabling the EGR in other previous vehicles has led to only positve effects on the driving and maintenance experience. Not had a DPF fitted to any of my vehicles until now and it clogged up last week and went into limp mode because the EGR temp sensor was faulty. As previously stated I tried to replace it, but was not succesfull as it was truly stuck in the manifold.
I do not feel removing the engine is a sensible option.
Will the DPF not clog up if the EGR is not functioning? it was my understanding that the EGR valve was an integral part of DPF regeneration.

your understanding is wrong - the EGR comes after the DPF - it is a closed system

hence why I suggested the use of Launch UK earlier in this thread

Mine is booked in early next week for EGR deletion and a gentle remap.

I´ll report back on the results. 2012 4.4 TDV8 Westminster - Baltic Blue, Jet interior

No I did not need to use the gun, just poured in the Launch UK bottle with a full tank of diesel, say every 5000 miles, been doing it for over 5 years and all good - easy life
