Yeah I'm the same .... and so is my FL2  Life is not a dress rehearsal!

Cold starts with diesels will be noisy until engine gets warmer, its caused by imperfect combustion conditions, performance is also effected still pining for my 3dr, no removeable hardtop, no drop glass tailgate, no roof rack, no pockets everywhere to stow all that man kit

My car cold starts no problem, lowest temp I've seen is -4. I'm wondering what cold start systems are at work? With my previous key operated diesel car, you would turn the ignition on, watch for the cold start heater light ot go out, then turn the key to start. With the LR2 all you can do is press the button. I've not noticed any cold start warning lights, and it certainly always cranks the instant I hit the start button, so no time for cold start heater plugs to warm up. Anyone out there know what goes on in cold start conditions ???

I get the feeling that 2-stroke oil would help things out! Watch for relevant Yamaha-Fan posts...

My thoughts exactly.
Come on Yamaha-fan, how does the 2-stroke perform in winter? This could be what pushes more people to try your suggestion. Out with the old (2007 SE)
In with the new (2012 Dynamic with everything). Now also gone.

To all interested:
our Freely 2 does have the latest technology in glowing plugs made out of a ceramic compound. With these modern plugs you do not need to wait a little time until the glowing plugs have reached their temperature. It will take only seconds!
With regard to the starting noise of our TD4 engine when cold, especially in winter, you can indeed reduce this considerably by adding the dosis of 2-T oil to the fuel.
The petrol stations offer from November to March what they call "winter diesel" to avoid blockage of the diesel filter, as the viscosity of diesel will get thicker the colder it gets (flocking of paraphins). This winter diesel contains flow-improving chemicals, which however, do have a negative impact on the cumbustion. This is the main reason of the noise - uncontrolled combustion for a little while until normal temparatures are reached.
2-T oil will not only increase the viscosity of diesel, but it will also increase the combustion willingness of the fuel.
Engine technicians speak of "washing of cylinder walls".

I have also noticed cold weather seems to labour starting - I would have thought with all the technology a sensor would delay the starter motor to give the glow plugs more time when it is cold. As you point out you can no longer wait for the glow plug light to go out before turning key to start position.

I wonder how owners in cold climates like scandinavia are coping or if they are modified for those markets

Yes Paul, you are absolutely right. With "increasing" the viscosity I mean "better" the viscosity in practical terms.

I've noticed about a 1/2 second delay between pushing the start button and the engine starting when it is cold weather, but doesn't sound rough at all. ______________________

I noticed a delay this morning too - it was 1 deg outside.

A cold morning ( - 8° ) the delay was also around 3 seconds before the engine start. My engine make weird sounds when started in cold temperature, but never fail to start properly... I guess it's normal
