Range Rover Sport EGR delete
Coolant going missing with no leak to find, white smoke on a cold start, then limp mode. On a V6 Range Rover Sport that is the EGR cooler. Mobile software delete at your location, £220.

How the EGR fails on a Range Rover Sport
The cooler cracks first. On the TDV6 and SDV6 the EGR coolers sit in the valley of the V6, one per bank, and with age and mileage they crack internally. Coolant seeps into the intake and burns off in the cylinders. The first sign is the expansion tank: down a little every couple of weeks, no puddle, no wet hose. Then grey or white smoke on a cold start, then the engine management light with P0401 or P0402 stored, and eventually limp mode on the motorway with a trailer behind.
The valve sticks second. Short trips and idling never get the intake hot enough to burn deposits off, so the valve fouls with carbon, the ECU sees a flow figure it cannot reconcile and logs P0401, P0402 or P0404 with no coolant loss at all. The 2.0 SD4 adds a second, low-pressure loop to foul. The TDV8 and SDV8 follow the V6 pattern with another bank of it.
Range Rover Sport engines covered
Range Rover Sport L320 2.7 TDV6, 3.0 TDV6 and SDV6, 2005 to 2013
The 2.7 to 2009, then the 3.0 twin-turbo. The AJD-V6 shared with the Discovery 3 and 4. The TDV6 crankshaft failure is a separate fault and the delete does nothing for it.
Range Rover Sport L320 3.6 TDV8, 2007 to 2010
Two banks, two coolers. EGR cooler faults well-documented.
Range Rover Sport L494 3.0 TDV6 and SDV6, 4.4 SDV8, 2013 to 2019
Same V6 family, same coolers, same fault. The SDV8 alongside it.
Range Rover Sport L494 2.0 SD4, 2018 to 2019
The Ingenium four-cylinder, Euro 6, twin-circuit EGR. Valve and cooler fouling on both loops rather than a cracked cooler.
Range Rover Sport L494 and L461 D250, D300 and D350, 2020 onward
The six-cylinder Ingenium mild hybrid. Newer, short record so far.

What the delete does to that fault
It answers both failures. The EGR circuit is closed in software, so exhaust gas stops passing through the coolers in the valley of the V6, and a cooler that has been weeping coolant into the intake is no longer fed. The ECU stops commanding the valve, so a valve stuck with carbon can no longer produce the flow error that puts the Range Rover Sport into limp mode. On the SD4 the second loop is handled the same way. Valves, coolers and pipework stay on the engine and stop being used. Codes cleared on the day, and the remap is permanent.
Is it definitely the EGR?
Three things help us confirm it on the phone. The exact codes from a code reader. Whether the coolant is dropping with no visible leak. The smoke: colour, and whether it is only on a cold start. If coolant has been entering the engine for months, the delete stops further ingress but does not undo damage already done, and we will say so on the day rather than remap a car that needs something else first. If a DPF light is on as well, both are handled in the same visit for £445: see DPF and EGR delete.
Questions Range Rover Sport owners ask
Is it definitely the EGR, or could it be something else on a Range Rover Sport?
My Range Rover Sport has been losing coolant. Will the delete stop it?
Does the delete cover the EGR cooler on the Range Rover Sport as well as the valve?
Will the fault codes come back on the Range Rover Sport after the delete?
