I started mine on Tuesday early-ish to take the kids to School and as it was on I was topping up the tyres with air...
It was around zero degrees to be fair but I noticed it was puffing quite a bit of white smoke.. normally would not notice as jump in and drive... Anyway as I'm waiting for the tyres to fill almost as it comes off choke, it subdued a Lot. I guess that's normal given the temperature etc Mines on around 108K now |

VCV could be aged, or glow plugs getting on, but it’s really cold weather it’s quite normal.
Do you use Millers diesel additive? That’ll help, also a tired starter or battery will be that bit slower to turn over as well, especially if the battery voltage has dipped a bit which is common in the cold. It might be useful to keep off your HU or audio equipment, and keep the interior lights completely off. That will reduce current draw in this weather, in normal times it’s fine but when it goes below freezing. Keep lights off, heated seats off and any kind of load prior to cranking / turning over. $W33T $0U7H3RN $UG4R 🇬🇧🏴🏴🏴🇮🇪🇺🇸⛽️🛢️⚙️🧰💪 Last edited by custom90 on 22nd Nov 2024 2:49pm.

Blue smoke on cold.start with a Puma seems to be normal, it's been discussed here several times over the years. Mine's always done it and is no.worse now at 278k miles than it was at 50k miles.
Changing the heater plugs is easy if the old ones come out but equally can be an absolute nightmare if they don't. You won't know which until you're committed unfortunately. |

There should be a DTC for any particular one, but best practice would be replace the set if that was needed. I think it would log a DTC, but not illuminate the MIL if that was the case.
I think as Blackwolf stated it’s fairly normal, if it continued for minutes at a say in excess of ten minutes you might have an issue. This is yet another reason to have a really good condition electrical ground too as the current draw on cranking is high, and the voltage drop is quite significant. If the resistance on the ground is high, then the voltage drop will be even higher, the starter will crank at a lower speed which will turn over slower, which will incline the engine to “cough” that bit more when really cold. Cold diesel start up videos on YouTube and you’ll see a lot, especially in places like Alaska and large diesels, block heaters in sub zero temp areas are common. $W33T $0U7H3RN $UG4R 🇬🇧🏴🏴🏴🇮🇪🇺🇸⛽️🛢️⚙️🧰💪 |

I don’t think a 2.4 will set a code if a glow plug is bad. Mine certainly didn’t and they were all toast.
Yes, the intake manifold has to come off. Change them after warming up the engine, they will come out easier. |

There are some faults that will produce DTCs with the 2.4 beater plug circuit but many which don't.

You have a webasto, coolant or air heater?
If former and therefore engine is warm prior to starting then it shouldn't smoke. If engine is cold it will smoke on cold ambient, this is normal. Usually easier to extract glow plugs from a hot engine. Cheers James 110 2012 XS Utility 130 2011 M57 bespoke Camper 90 2010 Hardtop 90 M57 1988 Hardtop |

I tend to think of logged DTC’s as a guide, not a guarantee.
They can be helpful, but they aren’t always acurate, or they might not be logged at all, or indeed nuisance ones. If there is anything suspect, DTC interrogation is worth it just in case there is a guide there. There are quite a few that will log, but not illuminate the MIL. So they can be a good indicator but not a guarantee, if it’s (ECM) seeing the correct values responded but the parts are old and not working as they should they might still not log any DTC even though the physical part isn’t performing so well downstream of the electrical values pinged back to the ECM. I always do use the glow plugs though, always have even when warm it only takes a few seconds. $W33T $0U7H3RN $UG4R 🇬🇧🏴🏴🏴🇮🇪🇺🇸⛽️🛢️⚙️🧰💪 |

I have a 2010 90 and noticed last winter that on start up that I got some (a bit) white smoke on start up which is only for a few seconds, but also noticed this didn’t happen when the weather warmed up. Just a Puma thing I reckon.

My engine has always been sluggish to start from cold in the colder weather. I did have a drippy injector but recently changed them and it was improved but the cold snap made me think that I needed to do something as when the engine did catch there was lots of blue smoke and un burnt fuel and rough running. Yesterday I put a complete set of glow plugs in it and difference was instantly obvious. Ran completely clean on cold start.
I got my OEM glow plugs from Empire Tuning for about £50 a set and it took about an hour and and half to do. Manifold off, be very careful not to drop the 7mm nuts that hold the connectors on. Liberal amounts of penetrant (NOT WD40) and it’s not too bad a job at all. Don’t think it could throw a code for individual plugs not working as there is just a bus bar arrangement that supplies them. Not sure how the ECU could measure current draw. Metered the old plugs and they all showed a resistance of around 20 Mohms, looks like they were all toast. No codes logged. 2011 130 Utility Body 2005 110 Van |

Hot engine did seem to help but be careful the plug tips that do the actual glowing stay hot from the engine for longer than the body. As I found out. 2011 130 Utility Body 2005 110 Van |

The 2.2 engine will produce a code to identify which plug is defective.. the glow plugs have their own controller which controlls each plug individually...but when it says plug no2...it will actually be cylinder 3 plug that is off as its no 2 in the firing order ..ie 1.3.4.2..👍

True, but the 2.4 has none of that.
