In the three days I have owned the car I have had three errors with the start stop system, two different error messages as seen in the attached photos..

The errors do not make sense since the engine was running in all cases..

And whats up with the aircondtioning error occuring under the start-stop system?

AC was off btw, and not trying to turn it on..

Anyone else had these?

Stop/start errors are quite common, I shouldn't worry about it.

As for air-con, check your glove box cooling setting, it so often left on by mistake. I only ever turn mine on when carrying drinks on a long journey.

The engine has to be running for the aircon to work, hence it overrides the start-stop system. 

Disabling Start/Stop system permanently with coding will solve Your problem definitely.

I find it quite nice combined with DSG. Easy to controll when it cuts the enigne or not.

That makes sense, but the AC was not turned on..

The a/c will work if the auto stop start kicks in but if the tempature in the car is reasonably different to what it's set at (I.e. Soon after starting the car) then stop-start doesnt work - I've had this and if you turn the required temp up or down (depending on ambient temp) the stop-start then works. I think the blower on its own would be referenced as a/c - so may explain this.

There's loads of other reasons stop-start won't work but another common reason is due to being mid dpf regen (on mine at least)

As gromle says it's pretty easy system with dsg - if in traffic just light brake and it doesn't kick in, stopped at traffic lights or longer than a few seconds and a harder brake push turns engine off. I don't really notice it now.

That makes sense, but the AC was not turned on..

Weather or not you have the AC button lit up or not doesn't necessarily mean the compressor is running/stopped.

 

As far as I've understood they're no longer the old type that is either on or off, but instead vary their circulation speed continuously based on conditions. It's usually a good idea to leave the system on Auto and let it decide how much cooling is required based on your slected temperature. Otherwise it'll just keep it running on the minimum setting and use higher fan speed to compensate.

Looking at the photo the a/c is set to auto. Last summer I was stuck in traffic and the car auto stopped but after about five minutes it restarted cooled the car then when off again.  I was quite impressed!

 

I get the other message "engine must be running", I have put this down to a DPF regen.

These are not Stop/Start errors..!!!!

They are just messages informing you about the state of the Stop/Start system so that you can understand why the engine has restarted on does not stop when you might expect it.

 

"Engine Must Be Running" means the stop/start system cannot stop because one of the systems in the car requires the engine to be runnning.

Usually this means that the DPF is in regen or has recently finished so needs to cool down the engine/exhaust.

 

"AC Requires engine to be runnning" refers to any part of the climate system requesting that the engine stay running not just if you have air-conditioning.

e.g. the current temperature is more than a certain amount below the temperature requested or the air is humid so the climate system wants to keep the windscreen clear.

 

These are perfectly normal message & don't indicate any errors with the Stop/Start system at all.

Everything is working at is should.

Can't stand stop-start! I once forgot to turn it off, and almost stalled pulling away from traffic lights, when it didn't fire up quickly.

It can't save very much in the way of fuel, and as for pollution I am sure there are far, far worse offenders.

This!

 

Not of these messages even contain the work 'Error'..... definitly a case of putting 2 and 2 together and getting 11....

I think the stop start system is really excellent - these advisories are helpful, because I want an explanation when it doesn't turn the engine off. Why do you want to waste fuel sitting at the lights? The restart time is minimal on my VRS.

Same here . barely notice it on my VRS with dsg.

Mine is awful to control, if I have the brake pedal in a position so it just creeps forward or at least strains trying to move then the engine won't stop (as expected), 1mm further pedal travel so the car actually stops the stop/start kicks in so I have to disable it every time I get to a junction as it WILL cut out the engine even if i only come to a full stop for less than a second.  Very annoying but as I've got a very early example of the Octavia 3 then it's probably a beta version of the software!

I agree it is possibly more useful in densely trafficked areas where you sit around at lights and in jams more, but not for where I drive.

Just don't like it coughing back into life every five minutes!!

I like to have the car quietly idling (and it is quiet!) and  just accelerating off smoothly when I start off.

I feel that stop-start is another one of those green party type la-la land toys, like wind turbines.

I'd sooner they had kept the black side rubbing protection strips on the doors of the Mk. 3 - much more practical !!

The system doesn't know you are only going to be stopped a second , it only knows you are stopped , or not stopped

I have to step quite firmly on the brake for the engine to stop. It might be, as you said, a firmware thing. Have you tried to ask for new firmware?

It's due a service in 2 months so I'll ask then.  I know there's been an update regarding ECO mode as well as that's downright dangerous on my car so it never gets used.

That makes sense, but the AC was not turned on..

If you've not got the A/C in auto and the fans arn't blowing more than the Auto setting would have them (fan speed indicator light goes out at Auto speed) then the only part of the A/C system that can be keeping the A/C going is the Glove Box cooling. Check the roller temp. selector is turned fully off ie. 0 and not the frost symbol

It was on because the setting "Auto" is on, when on Auto AC is in fact turned on. AC does not just cool interiors, it works well in the colder months by reducing the moisture in the air thus reducing misting inside the car. You basically pass the cooled air across the heater matrix, so you get hot air out the vents with no moisture.

Same here, I haven't had it accidentally stop more than a couple of times* since getting the car. Controlling it with brake pressure has proved quite straightforward.

 

And compared to a lot of other cars with stop-start I've driven, it reacts very quickly (pretty much on par with BMWs and loads better than in any japanese brands I've driven), so even if it does stop at an unfortunate time, it's back up and running by the time I start pushing the accelerator.

 

* (The couple of times it's been a bit late, it's actually felt so powerful from the start it would probably squeal the front wheels if it wasn't a 4x4.)

Very annoying but as I've got a very early example of the Octavia 3 then it's probably a beta version of the software!

I definitely had the beta version on my March 2013 manufactured O3 - so much so it took them over 6 months to fix the errors with even more beta software.

 

Any way, someone else has it now so I don't give a monkeys!

 

Have a look at this thread

On the original topic: I've had both messages, and I concur with the others that they are not real error messages, but merely for information based on valid technical reasons  (even though we may not fully know them)

 

I do have a question on a related note: Imagine you drive on the motorway at high speeds (in Germany for example) so the turbo is nice and hot, then you get of the motorway and straight onto a red light. Will the start-stop switch off the engine and risk damaging the turbo? Having a manual I can easily override the system by keeping the clutch pressed, but I never dared to try out if the system is intelligent enough. It's obviously intelligent enough to not switch it off when the engine is cold or needs to run for a dpf regen, but I'm not sure if "turbo hot" has its own sensor and related start-stop override.

 

cheers.

I remember reading that the turbo is oil cooled, and the oil keeps flowing and cooling the turbo even after the engine is stopped. (Don't take my word for it though.)
