Flat spot then limp mode 2.4 Puma
When it is first stared, my 09, 2.4 Defender is fine. When it has thoroughly warmed up, after about 30km, it starts to develop a flat spot, between 2500-3000rpm. Soon after that it goes into limp mode. If I stop and restart the engine it resets and is normal, but soon goes back to limp mode again.
It has been in and out of the dealer for the last 4 weeks. So far they have changed the turbo actuator linkage and then the complete turbo assembly, which includes the actuator motor. Neither had any effect and they seem to be struggling to decide what to do next. It shows no sign of overheating and the engine light does not come on. Fortunately most of the cost has been covered by the extended warranty.
Has anyone experienced a similar problem? Has anyone any idea what may be wrong?

Maybe it's something to do with the ECU. (??)
Maybe see if they have tried to re-read the injectors, running the Pilot Program.

SubscriberI recently had a problem with my 2008 2.4 that sounds somewhat similar. One of the wires to the plug on the turbo boost controller (wastegate actuator) was fractured internally. The loom was somewhat taut at this point and the outermost of the 5 wires was stretched tight, resulting in the wire being broken internally very close to the plug. It made intermittent contact so would create a fault, go into limp mode and then reset when the engine was switched off. The fault code indicated a problem with the turbo boost control (presumably yours does too, as that is where the dealer has concentrated their energy), I noticed this tight wire, when I put an ohm meter across it and gave it a jiggle, it came off in my hand. Repaired the wire with a little extra length soldered in, problem solved. This happened on the very last day of a 13,000km outback trip that involved some very rough tracks and severe corrugations.
Might be worth checking this on yours (I wouldn't like to be the dealer mechanic if they have replaced the turbo due to a broken wire).
Today the car was back at the dealer and after advice from Land Rover, they reloaded all of the soft ware, in its original form and then added all of the updates. So far it seems to have worked, and today I have driven over 300 km without any problem except that now, the horn sounds, when I lock it with the remote. Why would you ever drive anything else?

That alarm thing is a misslock warning... maybe they disturbed the bonnet switch... check it to be well plugged then push it down with your finger and lock...if no misslock that way adjust it to be sure that the bonnet actuates it well...it's NC contact so the bonnet must open the contact when it's closed if you see what i mean... it could be a door switch as well, investigation is needed

Mislock warning
Thanks for that, I will check it out.
