Hi Pete, thank you for your reply. You are absolutely right, it should have been "12" before the comma in both cases not "10". Unfortunately there does not seem to be a possibility the edit/correct my original post. I am not optimistic that more charging will bring the battery voltage any higher, but it still may. However, when driving, the alternator should produce something above 14 V and that is when the errors show up....seems strange but my knowledge is limited

Hi, may I kindly ask your support and guidance with the situation I am facing? Octavia III 1,2 TSI, 2005, ca. 65000 km, owned from new by me and the car has been absolutely trouble free up to now. I changed from winter to summer wheels When starting the car afterwards and driving I got the following messages: tire pressure warning (that was correct, as I had not stored new settings after the wheel change). So I stopped and stored the settings ABS/ESC failure tire pressure again AFS failure (cornering light) Start/stop failure Light on the button for the parking sensors is blinking Stopped the engine, waited and tried again with unchanged results. While I could imagine that I might somehow have done something to a ABS sensor during wheel change (even I did not touch them, not even the cables and have done wheel changes countless times), most failure messages did not seem to have any connection to the wheel change. I suspected a battery problem and measured voltage at the terminals: 10,1 V which is obviously very low. I had the battery over night connected to a charger. This morning I disconnected, waited for 5 min and measured 10,36 V, which seems to indicated a ca. 50% charged battery. The battery is still the original so no reason to complain that it seem to have reached end of its life. Are all the failures I gut indicated consistent with a faulty battery or should I suspect anything else? Thank you in advance

Manuals can be found here: https://procarmanuals.com/?s=octavia+III There is also quite a bit of other information about VAG cars and technology in general which I found useful/interesting, e.g. in the VAD SSP section on the top. Over the years I wondered more and more why people are so focused on Heynes manuals. I had 5 in total (2 for motorcycles and 3 for cars that we had) and I found them of limited use and in some cases just completely worthless. Few examples: - The manual for one Fabia we had was printed on a sort of toilet paper, most countries probably used better paper for their newspapers during WW2. This made the pictures which were not great to start with almost unreadable - In several cases I found false torque settings - For relatively simple tasks just the one important picture or guidance is missing which would make the task so much easier (or possible at all) - Before starting a task described by Heynes one might get the impression that with the manual at hand this should be straight forward just to find half way through that some important information is just missing - For simple tasks which do not require special tools and which can be done by a home mechanic they might advise to go to the dealership. They likely never perform the tasks they describe following their own description just to verify if what they put together makes sense. Instead of wasting many pages of describing how to get to the main bearings (something which hardly any home mechanic will attempt on a modern vehicle) they should rather put the effort into describing typical service and repair tasks properly. I won't buy any further Haynes manuals and rather try to get documentation from the manufacturer.
