I have a 2016 octavia 1.8TSI 4x4 combi which is due for an oil change. How much do I need? Can I find that in the manual somewhere? Local shop sells 4 liter containers. Will that be enough?

I got an error code in my 2016 octavia about light assist. I had it serviced now and they said there was a fault on the controller (not sure if that is the right name in english) that is inside the mirror(the one inside the car). J844/mirror needs replacement. Trying to get a used one. What is the part number on this? How do I know the exact model definition of my car (5e3, 5e5, 5e6 NI3 etc..)

I have lost the ball cap cover for the towing hitch and need a new one. What is the diameter of the ball? A local store sells one that fits 50mm balls, is that the right size?

I am well aware of how a heat pump process works, the energy input is usually electrical energy to the compressor. And the byproduct being energy absorbed(cooling)/released(heating) through the processes of evaporation and condensation. I was just a bit unsure how the electrical power consumption of the compressor linked to fuel consumption. I assume the compressor gets power from the battery. Which is charged by the dynamo when driving. But will the engine have to "work harder"/consume more fuel when using elecrical components like fans, seat heating etc? Or is it a case of "you get what you get" and the battery charges at a set rate when driving, and if you happen to use more than the dynamo charges(typically when standing idle), the battery drains?

How does the AC consume fuel?

I dont quite understand these modes and exactly what they do. 1. When I press the auto button - is it correct that it then regulates the fan speed automatically to reach the temperature that I have chosen? 2. What does the AC button do? What is the difference between having the button activated or not? If it is warm outside and I have set the temperature to say 16 centigrades, and have only the auto button active and not the AC button, will it not cool? Have tried reading the manual, but this is very poorly explained there..

little update here, I replaced the blower motor and the sound is gone 👍

Excellent. Thank you for your help good sir, I will order that one, hopefully it will fit like a glove!

the link you sent said"This part fits LHD (left-hand drive) vehicles only ". Does that mean cars with the steering wheel on the left side or cars that drive on the left side of the road?

i believe the speed control is working correctly, the reason im replacing it is because of a whistling sound that according to my local Skoda dealer probably was a worn bearing in the blower motor.

I have searched on a couple different auto part sites for that number now, and found a matching one for about 150£. I also found one that is supposed to match my car (based on licence plate number) at only half the price, but not the same part number. The cheap one is labeled "with internal regulator", while the most expensive one with matching number says "without internal controller". On some sites this was called "turtallsregulator" which translates to speed controller or rpm regulator. What does that mean? Is that something I dont need since it is not there on the matching number blower?

Have checked it now. Mine is the one ending with A. So that means i need a blower with the number 5Q1819021J?

okay, i'll try and see if I can dismantle it and figure it out. Thank you

Yes that would be good. TMBLD9NE0G0184778

I have decided to replace the AC fan myself and buy a new one online. How do I know which one to get? I went on one the major car parts sites for the norwegian market and typed in AC fan and my plate number. The search yielded several hits on different fans for different prices that supposedly fit my car. How do i know which one is correct? Here is the link to one I think may be right. This one said "with internal regulator". Others were without. What does that mean, and should i get the one with? https://www.skruvat.no/Kupevifte-P86230.aspx
