The error of the GPS is possible, if not likely. More so, I'm getting paid by the mile for using my car, therefore for possible GPS errors I need an accurate trip meter to see, if the GPS had any mistakes or errors. I've actually measured the distance with map tools and my previous car was great on accurate distance reading (19" wheels though). A known distance of 64,5 kilometers was around 66,5 kilometers yesterday with the 16" wheeler, so the distance error seems to be at least 3,2% or so. In time it will accumulate quite much and as mentioned, I'm used to having an accurate trip meter.

I've contacted the service, as it indeed still has 2 few months left of warranty (registered 6/2020). Let's see, what they'll say, I don't have high hopes though.

Hi, I've got an Octavia 3 G-Tec (2020), which has a pretty bad speedometer calibration. The tires are 205/55R16, and when driving 100 km/h (speedometer) the real speed is somewhere around 94 km/h. That wouldn't bother me otherwise, but it seems that it affects the mileage display too. I drive with my car a lot on workdays and have a GPS tracker so my employer pays me for the mileage I've had to use my car for work. I also keep a backup of my mileage on paper and I've written the start and end mileage on it. Last month the difference was about 10% (GPS says 452 km and my notes say 497 km). Usually I wouldn't mind if it was off a bit, but that is too much. Can we adjust the speedometer error with VCDS? If, how? Wouldn't want to buy new rims for that. Thanks in advance!

No, there is no obvious damage. Do you have to take the tailgate trims out (both lower and upper) to get access to the light unit? I tried this today after several weeks of hibernation on this matter (lack of time) and there are some clips that are TIGHT. I was afraid the trim might get damaged and thought to ask for instructions, if there are any. :')

This one.

The brake light next to washer jet doesn't light up anymore when applying brakes. Error code shows after starting the engine and applying brakes. Turn the engine off, start again and no error codes. After engine has been started and error appears, VCDS says: "11274 - Bulb for Center Brake Light B12C6 15 [009] - Open or Short to Plus Confirmed - Tested Since Memory Clear Freeze Frame: Fault Status: 00000001 Fault Priority: 1 Fault Frequency: 1 Reset counter: 28" Any idea what might be the solution? Does the light have a separate fuse? Do I have to replace the whole lamp, what's the part number? Have the wires been prone to break? How does the wiring cover come off from the tailgate? Many questions but I haven't had this issue with the car so far and I've got no clue on how to disassemble the tailgate plastics etc. Better be prepared if someone has experience already on this matter. 👍🏻
