After resolving my "front passenger door won't unlock" issue sufficiently to pass an MOT, my Octavia has now failed on the passenger door indicator repeater not working. However, the garage has ascertained that the LEDs function and that the problem must lie elsewhere. They can't find any wiring issues inside the rubber boot between the door and the car body, but neither can they find the cause of the problem. They have noticed however that the front passenger electric window doesn't work when operated from the passenger door switch even though it works when operated from the driver's door switch, which may or may not be related.

Does anyone have a clue where the problem might be? It has been suggested to me that the window regulator/controller unit may be involved somehow, but not suggested in a way that was particularly convincing 😆 However, if that might also be the reason that the door wouldn't unlock in the first place, perhaps it's worth

looking into further.

This happened to me about 4 years ago after a Skoda garage changed the door controller.

At the same time the door card puddle light failed to work. I took the car back to them within half an hour. They then spent about an hour setting up the correct features in software. No problem since.

In my case, since the door controller hasn't been changed, I guess that makes the door controller failing more of a plausible reason. Looks like a date with VCDS is in my near future to see if it will tell me anything useful.

Well, I gambled on a used controller unit from Ebay for a whole seventeen of your Earth pounds. Without fitting it I just swapped the wiring over and the indicator repeater started to work once again. Quite possibly that means the various other problems relating to that door are also fixed, but as tomorrow is the last day the car can be re-tested I swapped the controllers, reassembled the door and whizzed the car back down to the garage for them to look at.

After that I just need to deal with the alternator issue.

Well, I say "just". In fact I now have a log from VCDS with all the details from the car. I couldn't justify the price tag, but an acquaintance who has a copy kindly offered to run a scan for me. So I have a file with "useful" stuff like this:

Address 03: ABS Brakes Labels:. 1K0-907-379-MK70M.clb

...

1 Fault Found:

01309 - Power Steering Control Module (J500)

008 - Implausible Signal

Just need to work out how to interpret it now, but I see the manual is online so hopefully that will help me through.
