Start/stop eco mode
#1
I got a new peugeot partner in mid January, THE STOP/START function has only worked on about 4 occasions.
Handbook says it does not work in very cold conditions etc.
Weather here in Scotland has been very cold. Can someone tell me what ambient temp needs to be for it to work ? Confused

If it's cold outside and the engine's cold then it will never stop.

It seems to be more about the outside temperature than the engine temperature though. In the summer, if I drive to the end of the street from cold then stop, then the engine will stop, even if the temperature gauge shows it's stone cold.

Whereas at the moment - even if I drive lots of miles, it often carries on running or it just stops for a short time. Mostly though, once the engine's warm then it will stop - even if it's only a few degrees outside. But I'm on the south coast of England, which isn't as cold as Scotland.

I don't know whether it carries on for the engine's benefit or the passengers'. You can sometimes get cold toes when the engine does stop, as the heater goes cold fairly quickly.

Don't worry about it though - it sounds like it's working as it should and it should all make sense when (if?) the weather gets warmer up there.

I'd still swap our slightly warmer weather for your scenery though.

I drove a Qashqai wi stop start, and an electronic brake. And darkened windows. Vowed my next Berlingo would have none o them things.

Had to buy a 63 plate . . . mightnt be brill on fuel, but I will be keeping it a considerable time! I hope. . .new technology scares me!

We are experiencing a lot of issues with the batteries on the stop start cars, of all types. Seems they only last about half the time of an ordinary battery, presumably because of its type and use.
Problem is, the stop start will only work,when the battery is fully charged or there a outs, so if the condition of the battery is poor, it will never stop start.
Virtually every car we get in , the battery is in this state.
I would get it checked out with a quality battery tester, which must be correctly connected directly onto the battery terminals.
Replacement Exide AGM stop start batteries for the Berlingo/ Partner are 720 ah, and cost me £100 to buy give or take a few quid.

Lots of imaginary issues on this thread!

The start-stop on the Berlingo is very clever. It uses the alternator to restart it (using it as a motor by applying power to it), not the starter motor. The surge of power needed to do this is provided by a supercapacitor (e-booster), together with the battery. The supercapacitor is charged while you're slowing down, just before you stop. Citroen call it a micro-hybrid system.

The advantage of all this is that the restart is silent, smooth and instant. I've tried, and it's not physically possible to move your foot from the brake pedal to the accelerator before it's restarted - it's a fab system.

I worry about faults when they happen, not when they haven't!

I wonder if they used the " Dynasatart " as the inspiration for it, nothing much is ever completely " new "

Any dynamo/allternator can be used as a motor. The strange thing is that it also has a starter motor, which is used when you turn the key and start it - the whizzy fast starter is only used when it's doing a stop-start.

I guess the supercapacitor won't be charged when starting from cold though, and it needs this extra wallop to make the alternator spin the engine.

It works brilliantly - there's none of the uh-uh-uh-uh-vroom you get with a starter motor, it just goes from stopped to running.
