I know this is an older topic but I feel relevant. our fabia mk2 1.6 tdi developed faint warning lights which were traction light and washer bottle warning. Also with ignition off when entering the car, the door open light also faintly illuminates the oil light and I think one other. Any way after lots of bad words and wiggling things, battery check etc. I found a similar fault online of an Audi a3. Their solution was a dehumidifier!! So I warmed the car up, in went the dehumidifier and hey !!! All faint lights gone. So turns out it was damp bleeding current. took maybe 2 hours for it to be fixed. I hope this helps anyone else with this or similar problems. all other things like this I found online never came back with their fix.
