Is the stop\start disabled in sport mode? Some cars I've driven with stop\start have it auto disabled when sport model is selected.

Seems to be random if it works or not reading this thread though.

Question if you don't mind, when you do a regen charge do you disconnect the battery from the car? Not sure how the Jag electronics take to having the battery removed...

I have a ctek that I've used to maintain my boat/sportscar batteries over winters over many years, but much simpler systems.

S.
I watched the dealer just connect the very large chargers to several cars in the showroom and saw that they connect it mainly to the battery terminals. Only once did I see one chap connect the earth to the earth post in the engine compartment. So as the car is under warranty I did the same and have done several times since. The CTek charger has electronics in it to enable safe charging, without disconnecting. Mine came with 2 cables of which one set were croc clips style and the other for permanent fixture to be bolted on the terminals. I gave mine a regen charge some time back and then a couple of weeks later another regen charge. Since then I just give it a top up charge if I haven't driven it for 3 days or more. This usually takes around 3 hours. I suspect that this is unecessary and is just what I do. The S/S has functioned flawlessly ever since. I put mine on normal battery and AGM as the batteries are AGM type ( Absorbant Gas Mat). The AGM batteries need regeneration to release hydrogen around 2x per year. I have the CTek MXS5.0. The Jaguar branded item is a CTek charger of lesser spec and can be permanently fitted to the car.

Ian have a look at this for the better answer than I can give. It works in drive and sport but NOT paddle shift.

That is my understanding also. If using paddles and you want to use stop/ start ,say whilst having a long wait ,just hold up right paddle i.e. Back to drive and it will switch back on.

Number 6 on the "why it won't work" list is interesting.
It mentions demand on the climate control system requires the engine to be running.

I remember a member posting on here about a chat with a techie who said that stop start won't work until the internal temp in the car has reached the temp set on the climate control system.
I would think that the car having to heat the car until it achieves the set temp is a demand and does need the engine to be running.
Might explain a few failures.........?

Yes, I think 8 reasons why it starts again automatically and 9 reasons why it won't work at all must cause a lot of mistaken cries of 'Fault'. It's very complicated and that's why they called it 'Intelligent'. To my mind complicated means more chance of going wrong.

Exactly.
There are so many variables with the thing that it's not surprising there are many suggestions of a fault when it's actually working (or not as is the case) within it's design parameters.
I went out shopping this morning.
On my screen I get an icon when it isn't available.
Unlike normal I left it on and noticed that whenever I came to a halt the logo would come up saying it wasn't available.
No battery issues or anything else but it seemed to be the temp in the car.
I had set the temp to a pretty cool 19 degrees and didn't use the aircon as it was a shortish journey and the old fashioned open a window "aircon" was enough but obviously kept the interior a little warmer than the set temp.
Presumably the difference in temperature (hot or cold) is enough to stop it working.

Stop start again, sorry!

Well mine has eventually packed up completely now and no matter what I do it won't operate. So it is booked in on Friday for a health check of all systems. JTB00492V2 I will let you all know if it is sorted.

Mine's not been working all week but I suspect that is because the windscreen heater's been on as well as heater etc.

I assume it only works when there is little power drain on the battery?

There is a big list of reasons why it won't work including the car not being up to the set internal temp, etc etc.
Plus anything that requires the engine running to operate like the windscreen de-icer.
