Disco 4 (LR4) 2010 discovery 4 3.0 tdv6 EGR Blanking?

Mike Hawthorn · Jan 10, 2020

Hi Guys and Girls
A quick question. Can you do the software part of the EGR Blanking through the OBD port or do you have to remove the ECU and Flash the memory?

You can often do the software updates though the com port. However you normally need a sophisticated programming tool to do it. Some years of vehicle can't be modified, so it's worth checking first.

I think the GAP Diagnostics IID BT tool can do the EGR software delete, but I don't know if it'll do it on the D4.

hi mate

From what I gather it looks like a software patch that’s added to the gap iid, am nearly 99% sure the D4 has a DPF fitted so can’t blank the egrs

cheers for the heads up, must be something different then with the D4 , alas with the D3 it’s added to the gap iid and done via the obd2 port

so the D4 must be done via its ecu
