Hi all! I've just bought Seat Leon 2008 a couple of weeks ago, and the last weekend the red battery indicator started to blink on the panel. Also, the clock (and the last trip mileage) is reset every time I turn the engine off.
I checked the voltage with a multimeter, and it showed less than 12V. So I was hoping that that is the reason. I charged the battery, and it was 12.92V after it. But unfortunately, the indicator remained blinking and the clock resetting.
I also made some more voltage measurements:
- in the evening right after charging - 12.92V
- the next morning - 12.83V, and after driving to parking (~1km) - 12.78V
- later in the evening - 12.65V, and after driving from parking - 12.77V
As you can see, there's ~0.1V drop during the night and the same (even a little bit more) during the day. I suppose it might be a sign of a bad/old battery, that it's just not keeping the charge? There's also a small temperature difference between evening/morning, but it's only ~5 degrees celsius, so I think it shouldn't impact so much, right?
Also, I checked the voltage with the engine running, and it was 14.27V. So if I understand correctly, the alternator works well and is not the root of the problem, right?
I also checked the fuses and I found one blown. But it's "Headlight washer system" fuse (according to the manual), so I suppose it shouldn't be connected to the resetting clock... Also, I tried to swap this blown fuse with "12 V socket" fuse (both are 20A, and it didn't change anything.
So I wonder what can be the root cause of the problem? If it's the battery - then why didn't anything change after I fully charged it?
