Hello chaps! (and chapettes). My daughter is having a torrid time with her Fabia Mk1. The garage that she took it to has had it three weeks and sent it back exactly as it was. We have been less than impressed. Before letting a specialist electrics guy have a look, I thought that it would be worth consulting the Skoda Yodas. The battery is flat within a short time of being parked up, potentially overnight. Getting information from the garage has not been easy. There is a battery drain. I had figured that one out for myself. They have told me that they could stop the battery drain by pulling one of the fuses. When asked which one, they didn't know but it shut down a lot of things, although they couldn't elaborate. (I won't be going back there) I have now disconnected the aftermarket Chinese radio to see what happens, although that predates the problem by quite some time. There is potentially a massive clue as to what is going on. The electric driver side window doesn't move. That MAY have stopped working around the time that this issue occured although my daughter isn't 100 certain.

Thanks for the reply. Further investigation on the forum indicates that the sensor is probably at fault. If so it isn't a cheap fix but possibly better than having to go through the wiring like Sherlock Holmes looking for a fault.

09 Skoda Fabia Mk2. I have had the car a short time. EML light comes on. OBD11 shows it as P0135 O2 sensor heater circuit. Wipe the code and a day or so later, it returns. So I unplug the sensor on top of the engine. The resistance across the sensor heater (two white wires) is 8 ohms. A little high perhaps but it seems OK. I then test the voltage across the two pins that I have unplugged from with the engine running and there is 13v. Where do I go from here?
