Wondering if it's possible with the 3rd gen at all?. Using an OBDLink EX and windows laptop for example

The first step is to either remove the EGR valve entirely by using the best EGR delete kit or install block-off plates to prevent exhaust gases from recirculating. This step is relatively straightforward if you're comfortable with working on your vehicle.
With the OBDLink EX and a compatible software tool, you can read and clear trouble codes, but simply clearing the CEL won't solve the problem long-term because the ECM will continue to monitor the EGR system. To permanently disable the EGR system and prevent the CEL, you'll need to modify the ECM’s programming. Always make a backup of your original ECU map before making any changes, so you can restore it if anything goes wrong. Finally, while it’s technically possible to do an EGR delete on a 3rd-gen Range Rover using an OBDLink EX and a laptop, it's a complex task that involves more than just basic code clearing.
