Delay is heater plug opperation, first time this occured with me was March in Braemar when display showed "heater plug opperation" then after a few seconds starter motor cut in. Display then showed -16c.

How much is a cloud mudflap? If it's just a slight puff and you just see a bit of a haze in the mirrors it'll be fine, diesels can do it when cold...diesel is a form of oil. Mine: 2012 Golf GTI Edition 35

Its a big cloud of light blue smoke on firing up, then clears immediately. Doesn't happen again during the day even when engine cold. Just noticed in the mornings when engine cooled overnight. Seems to be worse in very cold weather. Beginning to fear valve seals. How do I diagnose this fault? (plus anyone got an idea how much valve stems and seal replacement this will cost?)

Happens on mine these last few cold days and mine has only just done 1k miles so doubt oil seals.

Think I just 'proved' my point?

You're right. Landrover specialist says the same. I wasn't waiting for the warning lights to go out. Tried again this morning and used correct procedure. Started fine with only a minor amount of smoke. Apparently, a small amount is normal for diesels in cold conditions. Phew! thats a relief.

But where are the instructions? The book just seems to say get in and press the button... SWMBO managed to flatten the battery on her FL2 this morning trying to start it. It had not been run all weekend and my diesel Passat showed -6 and was a pig to start as well. I charged the FL2 battery for a couple of hours and even then it was a pig to start (ambient temperature up to -1 by then). You should have seen the cloud of smoke out of the back! So what is the correct procedure for very cold starts? I thought that the FL2 was automatic glow plugs that ran when you unlocked the car so that once you went to start it, it should just fire straight up? (In the Passat I turn the ignition on and off a few times first to warm it through). I did notice quite a few times that the engine management clearly thought that the engine had fired and stopped spinning the starter when in fact the engine hadn't caught and it stopped immediately - I'd much prefer a key that you can keep turned until the engine really is running! |

You should get a few seconds (3 or 4) delay from pressing "Start" to the engine to start cranking, mine displays a message also something like "Engine will start after glow plugs heat up" or something like that. |

Place keyfob in dock, DON'T depress the clutch pedal (brake pedal if auto), just press the starter switch and wait for the car to go through it's system check and more importantly WAIT for the coil light to go out, then depress the clutch/brake pedal and push the start button.

No messages like that anywhere on our 07 plate. Maybe it's trying to tell us that the glow plugs are all dead and there's no point in waiting... |

Must admit that I never recieved the message till this winter, all the previous winters just had the short delay prior to cranking, I had read on here about the message and a software update so on the last visit to the dealer I asked them to look at the cold start, they did and now it gives the message. |

Cycled the ignition on and off a couple of times this morning and it started first push. |
