Freelander 2 2.2 td4 Electric issue

Hello i'm here because i'm troubleshooting a Freelander 2 for a friend of my.

The garage is not able to find the cause of the fault, so i will try to explain whats happening.
The car in question is a landrover freelander 2 2.2 td4 300.000km on the clock.

The car suffers from a galopping idle, and when accelarating the galloping remains. Only when you start asking for power the engine tends to run smooth, giving good power. i don't have the idea it is skipping cilinders, i find it a slow gallop. When i'm able i will make a video.

The engine check light is on, obd readout gives faulty EGR.
EGR valve has been replaced, did not help
Throttle body has been replaced (if i translate it right)
Swirl valves has been replaced

When you delete the codes, they are away for a short time, but will get back
Latest codes are:
- P042F-00 (Persistant)
- B10D7-94
- B10EA-14
- B10F3-11
- B1115-13
- B112C-87
- C1B15-15
- B1163-15
- B11F6-15

The EGR is consistant, the others tend to change each time you erase them.

I know the wire harness tends to scave under the air intake, but i didn't see anything worrying there.

Does anyone reconise this problem, or have tips for troubleshooting. On the Dutch forum, i don't get much response.

Hope you can help

Regards.

Have the necessary calibrations been done after the EGR and TB were replaced? When anything in the air path is replaced, an air path calibration needs to be carried out using JLR SDD or other suitable diagnostic equipment. Not doing an air path calibration can cause all sorts of issues, as the sensors and actuators don't function correctly.

It's also a good idea to check for wiring damage, the main harness under the air filter housing is a common place for damage, but anywhere that the harness comes in contact with body or engine parts is worth checking too.

The calibration has been done with original LR equipment.
I'm more and more afraid of faulty wiring.
Are there more common places where it rubs?

There are several places where wires rub, so you need to check the main engine harness right up to the ECM.

And the out come of the original post is what, it seems the OP like a few other owners ask questions but never return to give us the answer, how are we going to learn anything if there is no solution posted ?

Quite. It's one of my pet hates. It's just plain rude to not come back with an update, especially as folks give up answer their own time to answer said questions. It doesn't help the forum at all.
