Hello, sorry you are having trouble. I can not help but can I ask what is the purpose of KBX air duct?
Is this recommended to help prevent trouble like limp problems? Lo |

Hi,
I've had similar features  .
First question, do you have aircon? Then it can be (most likely) a temperature problem. Try reading the temperature whilst driving to see if that is the case. For some reason the temp can spike suddenly to 109/110 degrees and it goes into limp mode with no faults stored. If this is the case there are 2 reasonable cheap ways (for the links see below) to correct this and one expensive,a new allisport radiator. https://www.nakatanenga.de/fahrzeugtechnik...fter?c=147 http://www.roverparts.com/Parts/PEM100990G I know  it can also be the egr valve. If it doesn't open or closes fully during testing it will also go into limp mode but normally you will get an dtc, but not allways.
I know too that it can be the wire harness to the turbo, but normally you get a dtc code as well I know, also from experience, that it can be a leak in the turbo hose (can be a very small one). But normally you get that more frequent. a defender from 1984 pretending to be a puma with a touch of Range Rover |

I don't think so, an EGR issue will light up the amber MIL (check engine) on the dash, but won't trigger the limp mode. The DPF can, but that's not the case here because the 2.4 on a MY08 has no DPF. “A Land Rover immobilized is a moral defeat for the driver and bad publicity for the vehicle, […] it's up to you to do justice to your Land Rover!” - Land Rover Driving Technique. -- 2009 2.4 Puma Defender 90 SW 1979 Land Rover Series 3 88" |

Then my mil light must be broken
 That explains a lot.
All jokes aside, this is a current problem I'm having. So it is possible to have problems with the egr valve without the mil light coming on, but going into limp mode. a defender from 1984 pretending to be a puma with a touch of Range Rover |

What OBD2 codes do you get? “A Land Rover immobilized is a moral defeat for the driver and bad publicity for the vehicle, […] it's up to you to do justice to your Land Rover!” - Land Rover Driving Technique.

If i get an error code, it's P0404. But I don't get it all the time a defender from 1984 pretending to be a puma with a touch of Range Rover

A P0404 won't cause a limp mode, and won't even light up the MIL, it's an untested DTC

OBD II Fault Code
OBD II P0404 Fault Code Definition Exhaust Gas Recirculation Circuit Range/Performance What does this mean? NOx gases, which cause acid rain and respiratory problems, are formed when the engine's combustion temperature is too high (2500 F). EGR systems are used to reduce the combustion temperature, thus reducing NOx formation. EGR (Exhaust Gas Re-Circulation) systems are used to reduce the combustion temperature, thus reducing NOx formation. Code P0404 means that the EGR Valve Position Sensor is reading above or below the specified range. Symptoms Check Engine Light will illuminate In many cases, there may be performance problems, such as pinging on acceleration, when the engine is under load or when driving the vehicle at higher speeds In some cases, there are no adverse conditions noticed by the driver In my case no mil light and definitely performance problems a defender from 1984 pretending to be a puma with a touch of Range Rover |

Sounds like your EGR is stuck open. EGR issues rarely light up the check engine light but they do come out on the OBD diagnostics. Try having your EGR cleaned, if it still doesn't work, it must be replaced. This is what I think.

o4dn,
EGR fault can trigger both the MIL light coming on + engine going into safe mode at the same time. Happened a few times to my Puma 2.4 when it was only abt 6 months old. Dealer diagnosed it was a faulty EGR, which was replaced, and now 8 years forward all remains very good. Eric You never actually own a Defender. You merely look after it for the next generation. http://youtu.be/yVRlSsJwD0o https://youtu.be/vmPr3oTHndg https://www.youtube.com/watch?v=_GtzTT9Pdl0 https://www.youtube.com/watch?v=ABqKPz28e6A https://www.youtube.com/watch?v=rLZ49Jce_n0 https://www.youtube.com/watch?v=XvAsz_ilQYU https://www.youtube.com/watch?v=K8tMHiX9lSw https://m.youtube.com/watch?v=dxwjPuHIV7I https://vimeo.com/201482507 https://www.youtube.com/watch?v=ZSixqL0iyHw |
