You’re a star, thank you!

Hi, I'm having fun taking the door apart to replace the window regulator on my mk1 2006 Fabia. Having removed the cable bellows it's a bit crusty and brittle so wondering if I can replace it with a new one. I also broke one of the clips on the side where it joins to the car body. I can't locate a part number. If anyone has that detail that would be gratefully received. It's for the passenger side (UK car, i.e. nearside). Thanks, Jon

And... now seemingly a successful result. BCM from a VW Polo (same part number) arrived from eBay for the grand total of £17. Fitted, recoded, dash back together (the headlight switch was tricky). Result. Thank you all, especially @Breezy_Pete for your help. DM me and I'll buy you a beer.

I Just put a multimeter on the inputs and outputs, left and right, with the engine off and engine running. inputs: for both left and right, the chosen input pin goes from approx +4-5V to 0V when the stalk is moved to indicate in that direction. outputs: - when the indicators are working, for both left and right, the output pin alternates between approx +10-11V and 0V as the indicators flash. - however, when the left indicator does not flash, the LTS output pin does not alternate, despite the input still having dropped from 4-5V to 0V. My simple deduction from this is that the input is behaving itself (and I've already changed the stalk) but I need to get and recode a new module.

Back again Post holidays, with the help of a friend we got at the BCM. Looks clean enough. Didn't try a voltmeter test as just unplugged it to check condition. Sprayed it with contact cleaner and put it back together again. It seems to be behaving itself slightly better, the indicators working consistently on a short drive. Later, when I drove on the motorway I started getting a delay from pressing the stalk to the left indicator activating. Back off the motorway and it started behaving itself again. Needs a longer test drive. Question - I've seen a few on eBay with different numbers where mine has 'S1S34' stamped it. Does this have a known, specific meaning? If I were to pick one up and swap it out, I assume getting one with the same numberings on it, including this 'S1S34', would be the best bet. e.g. this one, https://www.ebay.co.uk/itm/185959278848 which also has 'II 1 38/06' where mine has 'I 2 13/06', suggesting a matching year ('06). Would this still need coding? (using the code pulled off the current unit). Thanks

Thank you @Breezy_Pete. Just looking at your other post here (https://www.briskoda.net/forums/topic/440110-right-indicator-not-working-with-engine-running/?do=findComment&comment=4949991) on how to get at that, and the post above yours on how to conduct a voltage test with a multimeter. I'll try and get a chance at the weekend to see if I can get to it to do some tests.

Another video, just to show oddness. Is this pointing to the BCM, seeing as the left indicator and the hazards are interacting in an odd way?

Ahh, except, on a test drive it’s now behaving just as it was. Tested it about a dozen times on the driveway earlier as well. Grr.

And... stalk replaced with one off Ebay. Indicator working again. Thank you all.

De Walt jobbie. But, cracked it - neighbour on the breaker bar, me holding the wheel 👍

Thought so. Neither my breaker bar nor my impact driver are shifting it, and I was reluctant to try the latter 😞

No airbag issues to worry about. But, this bolt should just undo, correct? With a 12mm spline socket on it.

Ah no, went out and tried it again, still intermittent/ only when also pulling the main beam flash, and then not every time. Let me see if I can get the wheel off, then it’ll be worth ordering a new stalk.

Well, I sprayed a liberal amount of contact cleaner into the stalk and that seems to have done the trick!

Thanks both. Yes, looking at the wiring diagram in the Haynes manual, attached, suggests whatever the input, it’s the same BCM output (16 as labelled). And odd that I got it to consistently come on with the main beam flash action, though as I say that tactic isn’t 100% reliable.
