Hi all, I'm a newbie to the Karoq and really enjoying driving it so far. Its an 18 reg1.0 tdi dsg bought from a Skoda dealer. Before going back to them would like to ask about my issues on here, hoping someone has a solution I can sort out.

First issue is the start stop showing as an error and not working. Drove 80 miles back from dealer last week and all ok, but since then doing town driving it doesn't work and shows as an error on the display.

Second issue is I bought a new 32gb sd card and put 1500ish mp3 tracks on. Put the sd card in slot 2 and it only showed some of the artists/albums. Removed the card, reformatted it and put it back in the car. Same issue but not displaying the same artists as before. Tried it a third time and again decides to randomly show or not show various artists but not the same ones as before.

 

Any help appreciated

Thanks

Could the car have been stood for some time due to covid?

My new car had been stood for about 5 months between build in Feb and buying it in August and consequently the battery was ruined and would not charge. If special batteries in stop start cars are completely flattened and left like that for a they often will not charge again properly. It had to be replaced. First sign of a problem us that systems start to fault, and stop start is first to go as won't work unless battery is well charged

I suspect you have too many tracks in one folder or indeed more folders than it can register? I think there are limits.

Yes I think it could well have been sat around for some time, I bought it a week ago but the previous road tax had expired end of March. Will get the battery checked, thanks.

I just put all the mp3s on the empty sd card, no folders at all, ill try creating folders for different genres of music and see if that helps, thanks.

 Have you tried looking at 'Vehicle Status'? It may say No Entries, but it shows the auto stop/start information symbol which you can press and it tells you why the system isn't working. Reasons can be many and obscure - a low battery is, I think, often stated a power consumption is high (I assume as the battery is charging). After minimal use during the first lockdown I was surprised how long it took to fully charge the battery (it needs to be fully charged for auto stop/start to work)

Hi, welcome to the forum, important to know that because of the energy recuperation system under "coasting" conditions, the battery monitoring module will normally allow the battery to charge to approx. 75% with the alternator - allowing spare capacity in the battery for charging under energy recuperation mode. Combine this with relatively low mileages and you can soon reach the point where engine idle auto-stop will cease to operate. Investing in a smart charger can be a good idea to keep the battery in better condition.  

Battery charging is always done by the alternator. The difference is about what drives the alternator: extra fuel, gravity (going downhill) or inertia (at deceleration). The last two are free, of course.

And in the case of the Karoq it’s the last two options it mostly uses to charge the battery and only using fuel if it really has to.

True, and the consequence is that many more times than in the past, we return home with the battery not fully recharged yet. So, in these times of different flavours of lockdown, it's easy to let the battery stand idle below 12.4 V for longer periods, which causes sulphation, i.e. battery degradation.

Thanks for your replies, I'll get the battery checked and then if need be get a charger so I can keep it topped up to a decent level, although tbh after a week or so without it I'm beginning to wonder if I even need the start stop to be running.

Here is my solution to the above problem.

 

I have a permanently installed digital voltmeter (drawing 8mA), connected to the cigarette lighter port and placed so that I can read it through the locked car's window, to get the reading at as close to "no-load" as it gets. That's important, as unlocking the doors disrupts the reading.

 

Then, I recharge the battery before the no-load voltage drops below 12.4 V, using a quality charger (mine is a CTEK) which doesn't switch to trickle charge as soon as 14.4V is reached (like some cheap chargers do), but also performs an "absorption phase" at 14.4V constant. That makes a big difference.

Disabling Start/Stop doesn't change the green battery charging algorithm.

It may be of help to someone if I point out that when charging the (installed) battery you shouldn't clamp the charger's negative lead to the minus battery post but instead clamp it to the mass post behind the battery itself. That's to protect the sensor placed on the battery's minus post.
