Thanks Pete,
I assume that this is the result (power loss to protect the motor), but not the cause. In the past, the car was doing the same trip in the same conditions (and more hard ones) without any trouble. My main concern is that the problem appears between normal conditions for a car (at least here). 30-35°C for 4-5 hrs at 120 kph with 2000-2300 RPM no A/C. So, something is not working OK. 
I will check the the intercooler and the other things and I will come back. Thanks again to all! Eduardo MY 2007 110 SW PUMA 2.4: Big Fog of 64' MY 1994 Jayco 1207 Folding camper: "El Tremendo"  Click image to enlarge |

Similar problem on my Puma 2010 with 20000 Km, when the outside temperature is cool the vehicle runs fine, but as soon as the outside temperature get to 35 deg C the performance loss starts. At 40deg plus I can only get about 105-110 kmph, with the acc on this reduces to 95 kmph. The handbrake lever gets so hot that you can not touch it. The body area arround the handbrake, more so on the right hand side also get very hot. Still need to get under the vehicle to see what is in this area that can cause this high temperature.
Engine temp gauge stay in the middle and no other warning lights are on. I suspect that a protection mechanism is being activated due to the detection of some high temp sensor. Defender Puma 2010 |

Car not jerking but with outside temp around 35ºC at idle I can hear some funny noises somewhere related to the injection system

Call me crazy, but I bet if you got a BAS remap with EGR closed, this would not happen. Even better would be a bigger/better intercooler. This whole week the temp at home & work has been 33C-35C. Leaving home at 0700 it's already 25C and on the way back home it's 35C, yet no loss of performance on my landy. Maybe I should put the OEM map back and see what happens... -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged

Hi, I know its my first post but been lurking for a while.
I'm going for a Temp problem if you haven't fixed it already, have had a couple of vehicles do this while at work. Once in the fast lane of the motorway. Turns out the thermostat was faulty, replace and vehicles fine ever since! Maybe worth a try for the few quid it costs! Dom |

Gents,
please see this from a fellow SaFa Puma owner who has also been having the power loss issue: -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged

Hummm,
I think that the problems is related with the radiator efficiency. Some weeks ago I clean the radiator using a garden hose with some pressure and the problem almost dissapear until yesterday at 120 KPH, fully loaded without the A/C (power loss again but this time the temp gauge going up for 1-2 seconds and then rapidly going down). I will check this week using an hydrojet and probably I will bring my ODBII sensor to check the working conditions Cheers Eduardo MY 2007 110 SW PUMA 2.4: Big Fog of 64' MY 1994 Jayco 1207 Folding camper: "El Tremendo" Click image to enlarge |

Eduardo,
check the coolant temp live data if you can, so you can at least rule out the CHT and the ECU employing the overheating protocol. Brian. |

Thanks Naks
 , looks like we are starting to get somewhere. I have just read the whole post on Landyonline (maybe you should post it for everyone's benefit), and it does seem encouraging. My warranty runs out in August - I've got a feeling I know what I'll be doing first. |
