Freelander 2 SD4 EGR valve replacement

Hi had restricted power mode issues with my freelander 2 SD4 63 plate the turbo has been replaced and now the EGR valve but still goes into limp mode. Does the EGR need to be paired to jeep? Thanks in advance for your feedback and support.

If any part of the induction system is replaced, then various calibrations must be carried out. So if the turbo is replaced, a turbo calibration needs to be carried out. If the EGR valve, or any sensor in the air path is replaced, then an air path calibration needs to be carried out.
You can't just replace parts willy-nilly, without proper diagnostics being carried out prior to identifying a faulty part, and correct calibrations being done after any faulty items are replaced.

Oh and it's not a Jeep, it's a Land Rover.

Thanks for your reply. I’ve had the turbo and EGR valve have been paired to the Land Rover but still going into restricted performance, due to EGR cooler fault. I’ve replaced the cooler with a second hand one but the fault is still showing
Any ideas please? Would blanking the EGR help?

A leaking EGR cooler won't cause any faults, other than either coolant loss, or coolant pressurisation.

It sounds like an air path calibration hasn't been completed, and the EGR is running out of travel, hence the restricted performance. It's an issue with the electronics, not the EGR gasses going through the system. You also can't blank the EGR, as it'll show an engine warning light.

Hi all, thanks for the response and support, the new EGR I used was faulty, I’ve replaced with a used one and fault has cleared but I’ve now got a turbo boost under pressure fault and restricted performance. It’s coming up with a turbo activator fault when scanning. I had replaced this unit when the problems started but it’s returned, Any ideas please??

When you replied the turbo actuator, was the replacement calibrated to the vehicle? These vehicles use complicated electronic controller units which can't be swapped over without the calibration routine being run with suitable diagnostic equipment.
Not doing the calibrations causes poor running, or early failure of replacement parts.

Hi, yes the actuator has been calibrated to the vehicle?

What condition is the hoses to the turbo? Any splits etc

They seem ok now, I’ve just replaced one as it had split and done a smoke test and all seems good ??

What code does it bring up, nodge has a full list of them and it helped when mine was smoking like a chimney.

P2263 actuator fault?

Could it be a chance it was a duff part that came faulty? Is there warranty with the garage.
