Update and hopefully closure! I am clearly old school and acknowledge it publicly but this update is to make anyone else out there aware if they have the same vehicle or same system. @Breezy_Pete thank you for the PDF Eng Management System doc - makes sense and shows me how out of date I am with technological progress in the automotive world! Thank you to all other contributors! Nub of the issue - yes the old battery was shot (and replaced) and yes I have changed an alternator that I now don't think was necessary - my bad and expense - ouch! However, despite a number of other forums talking about 'no need to tell the system' when you change the battery - you DO. Once the system was informed about the new battery - done by a mobile diagnostic chap with his techno wizardry, the system is now charging perfectly well at idle etc. Failure to do this and your system will continue to charge your new battery at the same rate as your failing one which, although won't be evident, will screw your new one pretty quickly with no apparent signs through warning lights etc. Consider deactivating your start / stop if possible - apologies to the environment as it does also shorten your battery life somewhat, Moral is - accept that I am getting old and sometimes it is better to pay someone with the right gear and up to date knowledge than trying do it yourself! Best wishes to all and thanks again - now to manage telling the wife how much I've spent in the last week - oh boy!!!

There is nothing remaining plugged in to any 12v socket. Stop / Start does work (though not always as depends on battery status). It would be really helpful to know if this is indeed the way that this model Skoda should operate as it seems bizarre that at idle the voltage reads 12.5 (you would expect 13.5v steady in old money) yet it does raise to 13.5v if you put the heater on etc and can peak at 15V - anybody else experienced this or confirm it is just the way it is! Many thanks

2020 Skoda Octavia 1.6 Diesel Est. Classic symptoms of no charge at idle - 12.5V showing on meter - will rise to 13.4 if heater, air con etc put on but whilst driving output fluctuates between 12.5 - 13.4 and 15v. Battery constantly becoming flat so battery changed (wasn't holding charge) - like for like battery (start stop compliant) fitted. No change - symptoms pointed to alternator (regulator) so that has been changed! Now £500 later and still the same! What could it be as it is driving me nuts and expensive and I need to get mobile for work!

Hi all - be aware as I am just discovering!!! On Saturday a fat pidgeon lodged itself at 60mph square in the centre of my front grille on my 2020 Skoda Octavia, breaking the grille and misaligning the radar sensor. Outcome - grill needs replacement and hopefully just the radar sensor re-calibrating as on the newer models the sensor is mounted on the back of the grill and not the chassis - so grille change = re-calibration! Can't be avoided as front sensor now showing as 'inactive' with warning light on drivers panel which would be a MOT failure. Apparently the fault can't be cleared without all the re-claibration done. Cost - a mere £800 pounds - ouch for the grill replacement and re-cal. If anyone knows of someone more sensibly priced than a main dealer (they are stating it takes 4hrs to re-cal) or knows how long this process actually takes please let me know. I reckon it should be the cost of the grille (price can't be that much and does the bumper need to come off?) plus re-cal (say an hour) so £800 seems really steep! Many Thanks
