The engine cuts power not only when acelerating in 6th, it does in other gears too, it's just combines hot day, up hill or towing....
But will check the wiring! Thanks a lot again! Cheers! |

Regard!
When this problem occured in your vehicles, after the ECU cutted power, what happened with the painel temperature indicator? (it increases untill "red" and decreases untill "normal" (middle) in the same "speed"? Like mine is doing....) Wich model from allisport do you recomend for standart ECU mapping? Thanks a lot! Cheers! |

Hey everybody!
See the video of the problem: &feature=youtu.be A friend here in brazil solved the problem making other "earths" between battery and chassis, engine, body.... Some thoughts? cheers! |

Hi Gabriel
Most reports I have is that there was a sudden loss of power while driving/towing in very warm conditions. The temp needle will go into the red sone very quickly and then return to normal after a little while. When the temp needle returns to normal the throttle response return. IIRC, Allisport have an offroad intercooler and a "sport" intercooler. The "sport" one is better for high speed cooling. |

Gabriel,
I was bored to have the problem all the summers (at least 2-3 times during each long trip) In my case the power cut are not related with a sudden increase in the temp dial (only one time happened). Finally I bougth a new sport intercooler from allisport and a remap from BAS but I cant tell you if the problem have been solved (Ask me in 4 month more) Cheers!

The head gasket was the fault when I experienced similar issues with overheating - checked everything else & when the head was off, the half full cylinder of coolant confirmed it was the gasket that caused the issues I had related to overheating.

Gabriel, I used to get to the power cuts when driving on hot days at altitudes above 800m above sea-level. But I never had the needle go into the red because of it. I changed my intercooler to an Allisport one about a year ago and the problem hasn't come back. Even my local dealer suggested I do the modification, as this was the only solution to the problem. They had done (or advised people to do) about 20 Pumas by that stage.
The only time I've had the needle go into the red was when one of the relays (sorry, can't remember which one) under the driver's seat was on it's way out (it may be under your passenger seat in a LHD vehicle). Also replaced and not recorded again. I would say if your issue is hot weather related check / replace the intercooler first, but if it happens all the time have a look at those relays as well. Have you done a pressure test on the vehicle? |

Gabriel
As above, I had the same problems, towing in hot weather, I suspected the worst. However for me it was the relays under the passenger seat that needed re-seating. I took them all out, put them back and never had the issue again. Apparently it is down to a specific relay but I can't remember which one. It's worth a try. I've spoken to a couple of other people that have had the same issue that turned out to be the relays. |

Thanks deep down and robharvey!
Certainly will disconect, clean and reconect all the relay under my passenger seat.... I´m in constant contact with Andrew from allisport and meking some tests before buy an intercooler... I´ve already tested without RAI, and don´t work... Now I took out the air box intake restrictor and testing..... Thanks a lot! Will keep you informed! |

Im working on similar problem.
2007 Defender 110 2,4 TDCi CSW with A/C. Symptoms, hot air blows into the cab, via heater even if turned to cold. A/C does cool it down a little, but A/C will not cool it down like our 2,2-. Car went into limp and cut the turbo on a recent journey. Temp needle steady, and no fault codes logged. milage 174K km´s. Bought the car in the summer. We changed all fluids on major service. It was running rough on start up, so changed the VCV after advice from Pete at BAS, cured the rough idle problem. While changing the VCV we took the manifold off to ease access, and the head is pretty gummed up with sludge from the EGR. cleaned this up as good as we could and cleaned the MAP sensor (very gummed up too). Vehicle is de-cat and no middle exhaust box you hear the turbo over speed / run. smells of exhaust due to De-cating and you can really notice the smell in the workshop. Checked the bottom hose on the Radiator and as it was stone cold and the top one was too hot to touch, we decided to change the thermostat. Once the thermostat was out, I flushed the entire system with a garden hose and checked the radiator for free flow. Installed the new thermostat and added new coolant. It hasnt gone into limp since this and Im monitoring the running temps, which climbs up to 95 c when pushed but drops to 89 c when coasting, constant load approx 93 with a ambient temp of 9C. Now we are approaching winter, im not going to complain about too much heat in the cab, but towards next summer I want to cure the problem, or at least know if I need to start putting away cash for a engine rebuild / replacement. it runs about 5 c hotter then the 2,2. I can smell coolant, but after dropping the coolant, and flushing the system, I believe this is residue on the block. Giving the fact that its done the milage, and not wanting to spend too much money on replacing coolant pumps, injectors etc contra buying a replacement low milage unit and replacing im not sure what my next step will be. given that it has the high milage, im leaning towards a low milage replacement unit, rather then mess around changing bits and pieces, then again if I dont have to change the unit and can get another 50 K out of it funds can be used else where. Sorry for a long post, but need to air my thoughts about the way forward. Cheers Glen "Rafiki" 2007 110 STW - Rolling rebuild. |
