Hello! Skoda Octavia 3 2.0 tdi 4x4 MT here.

 

I have a problem with my car, it started around 3-4 months ago, it will take long to start, but not every day, usually when it sits for more than 1 day. Now it s almost everyday. I want to mention that this is the first start of the day, the next ones are ok. 

 

The battery is kind of new (nov. 2023), the service said it doesn t need coding so it s not coded. I monitored a few days the voltage and it is ok (between 12,4-12,7).

 

I checked with vcds, i don t have any erros. 

Any ideas, someone that had the same problem?

 

I will put a picture with the injector values that i have and 2 videos with the starting.

Then they are wrong, like all (AFAIK) Octavia 3's your car has a BMS (Battery Management System) and start/stop, which means whenever the battery is changed the BMS must be informed of the battery change i.e. coded.

 

If the battery is the same Ah capacity and type then all that's needed is to change one digit in the serial number.

Can i do it via vcds or do i need something else?

Yes, you can do it with VCDS or OBDeleven.
