For the last 4 days the stop start doesn't seem to be working, various long and short journeys, and no error message, any ideas anyone ?

or is this normal?

Could be quite normal.

 

If you look in the Infotainment unit for the Start/Stop status what reason does it give?

 

And do you use a dashcam?

No dashcam I haven't been into the system yet [still on a learning curve] will have a look tomorrow.

thanks.

There are quite a few things that will make S/S 'unavailable' that are not faults.

 

I've replied to your post elsewhere as well

I would be interested in any tips to permenantly disable the stop/start, as it is the first thing I will be working on when I get my vehicle. I understand you can de- select it but it defaults back every time you drive again. 

Stop-start feels odd when you first get it. Leave it be, and you no longer notice it much.  It works just fine, if you let it.

Well after 1000 miles S/S returned and has worked perfectly ever since, and yes we quite like it, the time we will switch it off is when we have the caravan on tow.

I may be wrong, but it might turn itself off when you connect a trailer or caravan

Why?

It can stop the engine too soon, when approaching a junction for example, which then impedes a faster get away and unexpectedly stiffens up the steering.

 

On DSG equipped cars it can confuse the gearbox leaving vehicles temporarily stranded.

 

It slows down the heating of the cabin and shortens the life of the battery.

 

The headlights dim when the engine starts which can cause confusion and in stop start traffic the repeated off/on/off/on of the starter motor / engine can simply be annoying.

 

Not all models have auxiliary cooling of the turbo so turning off the engine (and therefore oil circulation) after a high speed run can shorten the life of the turbo.

 

If the engine isn't running it isn't generating heat which limits passive regeneration of the DPF on diesels.

 

It can encourage people to keep their foot on the clutch when stationary to prevent the stop/start from engaging, which can induce wear on the clutch and gearbox.

 

In my experience it doesn't make a noticeable improvement to my fuel economy.

 

I'd rather be able to turn it off permanently and then turn it on if desired in situations where the above situations aren't likely to occur.

This is a common misconception of start/stop. It isn't anything to do with fuel economy... it is there to reduce emissions when sat at junctions or in traffic jams, or start/stop traffic etc.

Oh but it is, fuel savings have been pedalled as a benefit of stop/start technology by almost all manufacturers ever since its conception.

 

In this example it appears to be largely successful too...

I haven't met the "turning off too soon" problem, but would regard that as a fault - and a dangerous one, to be dealt with immediately, by the dealer.

 

Some of the other listed "problems" shouldn't happen, either: one of the reasons for not activating shutdown, visible on the info screen if you select, is something like "passenger compartment not up to comfortable temperature", and I'd certainly expect my car not to turn off if the turbo was hot after a blast.

Unfortunately there are plenty of threads complaining about the stop/start turning the engine off whilst the car is still in motion.

 

Our Octavia will happily turn the engine off at the end of a motorway off-slip.

Do you have a link to these threads? It’s news to me and not a problem I’ve seen.

After a gentle 75 mph cruise (when the engine has been working at about 25% of its power output) or after a continental blast at 110, or after pulling a caravan up the Alps?   I'd expect the turbo to be hot after the latter two, at a fairly normal temp for the former.

It doesn't appear to matter, after a prolonged swift A road blast and it'll often stop the engine immediately.

But that's my point - quite how fast do you go on an A-road?   At 75 or so, you'll be using about a quarter of the power available, and therefore generating about a quarter of the waste heat that your engine is capable of dispersing.  It may well have decided that it's not hot enough to char the oil in the feeder pipes.

 

Having now heard about the system making wrong decisions and stopping the engine while the car is in motion, though, I think I'll be tempted to take my own peek at the oil temperature when I've been working the engine hard ...

This is probably the reason why having a trailer or caravan plugged in disables the start/stop.

Here...

 

 

 

And here...

 

 

And that's just in the MkIII Octavia forum, venture out of here and you'll see it is widely criticised.

 

 

Its weird how some people have problems with it, and I'm on my 3rd (and soon my 4th) MQB platform vehicle with S/S and never experienced those problems. I can control very easily if it cuts in or not by the pressure on the brake pedal.

 

Maybe it just works better in conjunction with DSG?

Oh no it doesn't. At least not on mine. Previous L&K Yeti disabled it when caravan plugged in but on the Kodiaq it's still operational.

Seems they have made an exception for the Kodiak then unless they forgot to code it properly.

Factory fitted towbar?

Factory fit on the Yeti and on this Kodiaq.

I must admit I was a little surprised when the stop/start sill operated.

If I remember correctly the Yeti used to show the symbol for disabled stop/start after van was connected.
