I am from the EU, I think it's the same for everyone

Sorry to hear it's different. Such a shame they changed the solenoid but managed to still use a part that get broken, seems like you have the newer version. Can you specify the exact model you have and year and month of make? I am yet to take apart my selector lever module, the warnings are annoying but I don't want to do anything about it if not really necessary, I have the NX5 version

Hi, this was actually my exact experience! Though I am not sure what loud noise you are talking about, maybe I wasn't paying attention. It started occurring now more often. Before I could not read the error with VCDS but now I can. This error matches what I read online elsewhere. You could most likely fix this by bending the contacts on the solenoid for the park. The deal with the park button is - if I remember correctly, that when the solenoid is active, it prevents you from pressing the park button - this is in the instances where the car would be moving and the computer would want to prevent you from engaging the park gear. There should be no issues with driving and while driving connected to this I think - unless it would make it possible for you to engage the park gear while driving, I did not test this for obvious reasons. Maybe just take extra care to not press the park gear button. You can google "P27F5 00 – Shifter Lock Solenoid 1 (Stuck Open)" to find the contact bending solution I mentioned. It's most likely this.

My problem is that with VCDS I don't read any error ... One time I even left the car running with the error on display, got my VCDS, connected, and still no error.

I also saw some Russian guides how to do it yourself. Supposedly it is trivial - there is just some contacts that need bending. But I don't think this is the issue with my car since this only appears during driving ... I am not that much bothered by the error that I would go and try to fix it myself.

So this issue was fixed on your MK3 Octavia? Not mk4? There is supposedly an update for the MK4 octavia as well

Thanks for sharing this. Below is the update from my car, data from 22nd December 2024. Charge related ageing down 6%, performance related ageing down 4%. Total recharge was only 210 Ah from battery replacement and around 100 Ah from last update. So in the span of 36 days this decrease occured. On thing to not is that the other values still look fine and that I did not drive my car a lot in this time.

Another update Surprisingly, the car computer estimated charge and performance degradation has already increased ... Like wtf after only 100 Ah of total re-charge. Also, the adapted capacity shows up as 84 Ah although its was and still is coded as 72 Ah. This number automatically went up from last time (see first post). The internal resistance also shows up as a bit increased I will be posting further updates about the battery here:

Hi, about 2 weeks ago I got my EFB+ car battery replaced for a new AGM battery. This were the stats from the computer on that day: -------------------------------------------------------------------------------------------- Now, about 14 days later: Battery capacity should be adapted to 72 Ah So far, based on the stats from the computer, I am not impressed with the AGM battery but time will tell. I think I might have done only about 1000 - 2000 km in this time. Also, the adapted capacity shows up as 84 Ah although its was and still is coded as 72 Ah. This number automatically went up from last time. One important change however is the weather, 2 weeks ago it was like 15 °C, now it's below 5 °C, so the battery is taking the cold weather well Related post of mine:

I can also add something to this but I can't say for 100%. I built a testing rig to measure charge and discharge of the used 12V EFB+ battery, supposedly 72Ah when new. I am a bit surprised and for this reason doubtful but seems like the battery only has about 25 Ah capacity left, so about 35%, while the on board system was showing as it having 83% of capacity left - usable battery capacity when full. Sadly I do not have a brand new battery to test this out and see how much charge I can put in and take out, so take this with a big amount of salt, but basically I did this 2 or 3 times now, measuring how much energy in Wh and Ah I put in and get out and it seems to be at the 20 - 25Ah range. In the screenshot you can see all the curves, altough because of some error the top left is marked "Wh", it actually represents the voltage, I current in amps, and below power and amper hours, This is the discharege of a fully charged battery. And here are the charging charts of a fully discharged battery (around 11.6V empty) For anyone wondering - this was done with INA211current sensor and ESP32 microcontroler, the dummy load was a heater element. I also did another test where I connected the used battery to a 12V to 230V inverter, connected a handheld vaccum machine to it, and it was able to put out about 500W, powering the vaccum, while the voltage on the battery dropped to 10.8V, so about 2V, if I can trust the voltage indicator on the inverter. Using a much smaller 12V battery, that with my tests puts out about 12Ah of capacity, the vacuum would not even start because the voltage drop on a much smaller (not a car lead acid battery) battery is so high, the inverter doesn't work. I am planing to use this used battery with an inverter for camping reasons or for a portable 12V refrigerator I have, should be able to power it for like 2-3 hours.

Of course I did not miss his post but I was more curious about how to do it with VCDS since it has a SFD lock. Maybe it would even be possible to do with VCDS but I did not know I need to manually clear the errors before setting up a new battery in the computer. Also, for me personally there is a big difference if 1 person says I don't need to keep power or if 5 people say that. Would make me more confident.
