Wow I didn’t know that, it applies the same to the interior lightings or number plate bulbs? I was about to replace interior bulbs with LED ones, was just wondering if they may cause any kind of issue with the cars ECU? Any suggestions are appreciated

That’s absolutely correct, one day for about half an hour I left OBD2 connected while I was driving and looking at the live data, then when I finished I just disconnected it, and apart from that I got an little phone charger which has a little digital display where it shows car battery voltage in real time, I keep that connected most of the times.

I was checking live data using OBD port via Carista App and at the same time with my phone car charger which shows the voltage, although car charger shows always .02 value lower than the OBD2. If OBD is showing 14.8v, car charger will show 14.6. as @RoddersUK said BMS must be doing it’s job to not overcharge the battery hence it’s shows 13.2 while driving and when braking or just release the accelerator it goes above 14.5. I keep the car charger connected while disconnect OBD2 after checking live data.

Hi there, is this the reason voltage goes up and down when the engine is running? im asking because I’ve noticed that my car shows 13+v while driving and goes upto 14.9v when I leave the accelerator or press the brake pedal. It keeps going up and down between 13 to 14.9v with the engine running or driving. hope that’s not an anomaly with the alternator or battery itself. 🤞 😀

Yes that’s correct I was sitting with the ignition on for 10 min while navigating Carista menu etc. so in the morning before starting the car up, what should be the minimum voltage and charging level on it please? I can check the voltage in 2 ways, one through phone car charger which shows battery voltage, and two with OBD. Let say if the voltage is less than 12.2 or 12v, is it considered to be abnormal? thank you for your reply 🙏

Wow I didn’t know my 2015 Skoda had Micro-regenerative braking system, so the system had it charged to 80%, and 5 min drive and braking charged it upto 89%? If that’s the case, that’s really impressive. thank you so much 👌

Thank you so much everyone for your support, just a quick one please, If I leave the car parked at night, what am I supposed to get the value on charging levels before starting it again in the next morning? Is it supposed to be 100% or could be less than that. ive driven the car the next morning and after a 5 min local drive I found these levels on live data. Is it normal or is it supposed to be 100%? and can I use Carista OBD while the engine is running to see live data or it always need to be ignition on only. Thank you all so much

So VW has been configuring their batteries wrongly? I hope not lol, 😁 so these are the only options available with Carista OBd2, no fleece here.

thank you so much for the reply, AGM was already selected for the old battery, I’ve just changed the other values, hope it’s correct and keeps working as it should.

Good evening everyone, my 2015 Octavia had the original VARTA Battery which I replaced today, asked a garage to give me a quote for fitting it but they never got back to me. I replaced it with a YUASA 9000 and done Battery adaptation/coding through Carista OBD2 adapter, so far car starts very nicely. I’ve replaced the values from original which was the following: please kindly see the attached pictures. could anybody please confirm if I’ve done things the right way or the wrong way. Thank you so much.

Hi everyone, whenever rains it smells really bad in the cabin, specially when I turn the aircon on to defog the windscreen, If I keep the temperature high it disappears after a couple of minutes. Someone told me to change the cabin air filter, there are 2 or 3 different types of filters available, 1, standard 2 activated carbon 3, activated carbon with fungicidal effect What filter would you recommend please and advantages and disadvantages of the 2 ( activated carbon and with fungicidal effect). Shall o go for the 2nd or 3rd option or just the standard one would do the job. Skoda Octavia 2015 hatchback DSG 1.6 81 KW Thank you
