can anyone confirm how the CHT works in terms of resistance increase or decrease with temp (assuming this is how the signal is relayed to the ECM). normal physics suggests the resistance will increase with temp but I've yet to find anything 'normal' with my defender. ?

I think that the buish/whiteish smoke on start up in cold weather is a normal 2.4 Puma Defender characteristic, certainly all those I have been involved with have done it.
I didn't think that cycling the heater plugs twice actually cycled the heater plugs twice though, since I think they're under ECU control and aren't as straightforward as heater plug used to be. I may be wrong though. |

It does cycle the times you reapply the ignition. check the voltage drop when doing so.
The ecu does however continue to pulse the glowplugs when the engine is started to aid heating and emissions. Discovery 4 SDV6 Landmark F31 320dA Msport xDrive LR Defender 90SW TD4 Stornoway grey 320d E46 E70 X5 3.0d Sold! FFRR TD6 - Sold |

Hello all,
I have got a puma 2.2 and he make a big smoke when cold morning. I live in ski resort and when we got -20°C, smoke can stay 2-5 min and I can't go because engine don't have enough power. I think white smoke when weather is cold is normal. |

Mine did this white smoke shade of blue at times.
Diesel fuel additive like forte helped a little, but then had the EGR valve removed and cleaned and then it stopped. |

Like snowy says, our white smoke on start up went away when a new egr was fitted. Cane back a year or two later though..

In france, we have got 3 kind of fuel. One for summer and one for winter. But in some fuel station ( ski resort for example ) we can find "Grand froid" fuel. He can run below -21°C. Yes I always use this kind of fuel. But I must install a heater pad on fuel filter in winter.
If I understand you say that my EGR valve must be cleaned? or removed? |

You can clean it, or blank it off and get it electronically disabled.

In 2012 I've tested 5...7 Pumas. They have been 4...6 yrs old.
From my memory: 50% okay // 50% did smoke, only whiteish - it depended on mileage ... I've been slightly confused and decided to buy a new car. |

it also depends on the oil and how long its been sitting.
I must say , when I was driving in the Savoie (Les Saisies) my defender also emitted more white smoke and ran worse , also the exhaust stinks a lot. I think its due to less oxygen and colder climate. After that week my defender Chuka chuka EGR sound became worse! . if you live in the alps I recommend a Webasto or similar. My dad just bought a Landmark Discovery 4 and he ordered it with the fuel burning heater just for this reason.

Its so easy to see if your glo plugs are in good condition. You just need a multimeter that can measure resistance of less than 1 Ohm. Measure between the nut of the glo plug and the connection point after pulling off the lead. The resistance should be around 0.7 Ohms but 1 or less should be fine. Don't forget to measure the resistance of the meter leads by touching the probes together and deduct any lead resistance from your measured glo plug value. If the glo plugs are measuring much higher than 1 Ohm they either will not glo on cranking at all or will take an age to heat to a glo by which time the glo plug voltage has been reduced by the ECU so will never get to a glow condition. If in doubt unscrew the glow plug in question from the cylinder head and connect with thick copper leads across a 12V car battery or a 12V source that can deliver 20 to 24 Amps or more. The plug tip should visibly glow a few seconds after connection. Be careful, glowing is obviously very hot but if they don't glow don't assume the end is cold it could still be hot enough to burn you. "You are never to old to learn something new" |
