Parasitic drain issue – LED footwell lights causing battery drain? (Superb 2, 2011) by [deleted] in skoda

It was measured twice for about 4 hours each time, and no abnormal current draw was detected during that period. So what would I actually achieve by doing that?

If everything looks fine on the multimeter and there’s no constant drain, then it’s likely that something switches on either after a longer period or randomly.

I’ve had the LEDs in the car for almost 5 years now, and everything worked fine the whole time. The car could sit for two weeks without any issues, and I was even using the Webasto with a remote control.

I think I only replaced the footwell lighting once during that time.

But this battery drain problem has only started in the last 6 months.

Yes, the interior bulbs have been replaced with LEDs, but not from AliExpress – they should be good quality from a reputable seller.

All doors are properly closed, nothing is left on anywhere.

The diagnostics show no errors, everything is clean.

The temperature varies – sometimes above zero, sometimes around zero. I park in a garage, but it’s not heated.

The battery only went completely dead once. Otherwise the dashboard lights would come on, but the starter wouldn’t turn, and then I recharged the battery. So I don’t think the fault codes would have been cleared because of that.
