Initially you will need a full diagnostic code read preferably using Skoda Diagnostic Equipment. This places the code in order of diagnostic preference.
Potentially these codes and problems you are having are all battery related. Did you purchase the battery from the Skoda Dealer or is it from an Aftermarket Parts Supplier? This could cause an issue if it is not exactly the correct battery. It is not just the Voltage you need to look at. It is also the Amperage and the Amp/Hour of the battery. Modern Charging systems rely on the correct battery being fitted.
Disconnecting the battery performs a System Reset so no fault codes will have been present in the system. Most fault codes will not reappear until two drive cycles so in effect after the system sees the same fault twice in a row.
Looking at the codes you have presented a couple of them are to do with Idle Air Control and Throttle Systems. It may need a relearn carried out on these systems. If the battery was faulty then it could have affected the software settings for these. This should be carried out at a Skoda Dealer who can also check if there is any software updates for the Engine Control Module and the Battery Control Module. If the vehicle is still under warranty (3 years / 60000 miles) which it may just be then this could be carried out under warranty.
Hello, I am Jose Sebastian. Your automotive expert, It's a pleasure to me to attend your question. Thank you very much for trust in just answer.
dear costumer according to the error codes i see problems at the air intake and throttle potentiometer regulation problems, remember that the potentiometer have to be coded through a diagnostic equipment with Skoda software,as you bought one replace it but remember that you have to code it and check the connections very well. related to other electrical faults i recommend you to make a fuses and relays checking because they are likely to have been damaged after battery charging problems.
Dear costumer is not that you have to go to a dealership, bacause any external workshop with a skoda software so you can do the reset. I really think that you have the throttle body programmed i would not have replaced it before i had coded the potentiometer again with a diagnostic equipment, but as you tell me that you have a replacement take advatage of replacing it but remember that you have to code it, both the restoration and this coding is not necessary to do it in an agency.
Dear customer, a pleasure to serve you.
