K9 auto, slow to heat up.

[Ted3377]

Hi, 
I've got a 2019 Berlingo van. From new it's worked very well. Lately I've noticed that the engine takes longer to heat up. I does reach normal temp on the gauge after some miles.
Does anyone know the location of the engine block/coolant electric heater units? 
I know it could be other things causing this, but I think the electric heaters are the most likely, as once the engine heats up, it operates well, and it starts well once the Glow plugs have operated.
Any help would be appreciated
Ted

Are you certain it's not just the colder weather?  These engines are efficient and, compared to older diesels, convert more fuel energy into power rather than heat, so take longer to heat up.  I've found that, in cold winter weather, my K9 van can take 10+ miles to fully warm up, if I'm not loading the engine by going up hills etc.

There was a thread on here about how you could force the electrical heater to operate, but that only works where you have a switch to operate the heated rear window, eg on the Multispace, not the van. Unless someone knows a different work around for that. https://www.berlingoforum.com/thread-20367.html

Hi 
Thanks for your message. It might be that, but I've had the van from new and it appears different lately.
If this model and year has electric coolant heater, it would be a good thing to check just to see if they are working properly.
It's not a major problem and does get the normal temp and stays there during long trips.
Thanks for your help.

Hi
My 2018 K9 1.5 Blue HDI takes for ever for the engine to come up to temperature, but once at 90degrees it never moves. I have stopped the car after 9 miles and checked the radiator hoses and they were stone cold so the thermostat still hadn't opened. I don't find the heater too bad but what annoys me most is the abysmal fuel consumption until the engine gets up to temperature, it really does make a huge difference.

I have read the previous thread but I am still confused as to exactly what I need to do, to get the auxiliary heater to work. The thread talks about setting the heat to maximum, setting the blower to full, set the air direction to screen and turning on the heated rear screen/mirror heaters. Do I have to do all of these things to get it to function?

If you have it, yes. Not all vehicles have the auxiliary heater, and vans have it too if specced from new with that option but it's not standard kit.

Set all the controls to hot and put the rear demister on (which on the van, only heats the mirrors) and this triggers the auxiliary heater to switch on. Even then it has to be below 4° I'm sure. My last van had it but the new one doesn't.

Also this auxiliary heater is not a coolant heater, it's an air to air heater mounted in the heating matrix area.

Extremely slow to heat up. Defa and Calix only offer oil pan heaters, this engine type does not allow free circulation of coolant, so no regular block heaters available. I did find some forced circulation heaters when I last searched.

Thanks for that. I will give it a try in the morning. Supposed to be around 1degree here overnight.

I would agree with the fuel consumption as i am easily 15 miles to the gallon worse off until it is near normal operating temprature. I would assume it is because it is in some sort of cold start mode when its cold. Also agree on the heating of the engine that takes forwever. Nothing new as it has been like this from new and my garage advised that a lot of never vehicles are now the same. I am easily 10 miles maybe 15 miles in very cold weather before it gets to normal operating temprature but in the summer this is only 4-5 miles at the most. What i do find very odd is how quickly it cools??? I can be in the house for 30 min and i come out and it does not register on the gauge at all until i have drove for a few minutes again.

Wow, I thought that was just me, I drive for easily an hour at the weekends and the engine is at 90, fully hot, jump into the local supermarket when I get home, come out 30 mins later and the engine is stone cold again! Down at the bottom of the gauge, no heat all the way to the house 5 miles away.
