Big day planned for tomorrow. Refurbed injectors and a much lower-mileage high-pressure fuel pump getting swapped in, I hope. Also the cam follower for the HPFP, unless the original looks much better than expected for nigh-on 160k miles. The company that cleaned and tested the replacement injectors very helpfully also changed the PTFE seals and the o-rings at the top, so should be reasonably idiot-proof to fit. 🙂 Anyone swapped out these items? HPFP has to come off to get injector rail out, so looked into that too, and picked up a far lower mileage one from ebay, for not a lot of money. Apparently the cam follower can get worn to the point of perforating, so I picked up a Febi one of those for not much over £20 via amazon.

If you let me know reg or VIN, I can look up what was fitted at factory.

There must be lots of much better ones to be found.

Scrap it, do yourself a favour.

The Octy probably doesn't have a clutch. Just a shear plate. I'd guess that the Fabia has two electrical connectors, the Octy just one?

Look up anything and everything here: https://www.lllparts.co.uk/catalogs

Fuel pumps in cars have their intake sprung against the bottom of the tank, so they suck up whatever is there, irrespective of fuel level. Amazing how few people understand this.

Something that sometimes bears fruit is to look at ebay listings for any given engine code. In this case probably best if they include gearbox too; but there are usually decent photos taken from all directions around the engine, so often can be helpful in finding locations. As you say though, de-cluttering the engine bay by removing relatively easy things like air pipes and airbox often opens up vastly improved visibility and access. I'll give ebay a go and let you know if I find anything.

Finally defeated the ECU anti-tamper bracket yesterday afternoon, so that I could get in and check continuity/shorts for the oxygen sensor wiring. Since almost day one of our ownership, stubborn lambda sensor faults pop up putting on the emissions light. Both sensors replaced with good quality items, and no wiring issues discovered yesterday. Hoping it turns out to be injector related, as claimed by the garage the previous owner used. I'm not sure how they came to that conclusion, but they claimed a couple of injectors were leaking, apparently. I've (cheaply) acquired a set from a much lower mileage 1.2 TSI, and had them cleaned and tested by a localish outfit that I trust. Should be swapping those in next week I hope.

I'm not sure what the grease type is that's inside them, let me know if you find out, please. erWin Skoda is very good value. You can buy 1 hour of access which includes ability to download pdfs of all kinds of info. 7 Euro plus tax. Once you have registered, logged in and paid the "flat rate", go to individual vehicle info tab.

Measure at the connector for the motor with ignition switched on, to be sure that 12V is actually getting to that pin of the connector where the black/blue wire goes. You said you had checked/tested all the wires from motor to 28-way, but that was with incorrect circuit info.

Yes.

Try the other end. Possibly a LHD-biased handbook.

This should match what you have. You can see that fuse 11 does matter here.

That's the next generation wiring diagram, from March 2010. No LIN connection to BCM on previous one, like yours, or the one before. So BCM isn't relevant. Fuse 11 checked? That wire isn't on your diagrams. Will add correct diagram shortly.

Check fuse #11, which supplies that ignition switched 12V to wake the motor.

Repair all broken wires and check from 28-way connector at hinges to window motor connector, referring to circuit diagram.

The wire that might be broken supplies an ignition switched 12V to a thin black/blue wire going to the motor connector. When you work them by the key, this ignition switched 12V isn't required.

Have you checked for broken wires in the door loom, under the rubber cover in the door hinge area?

I see, you are in a country where you drive on the right hand side of the road. So 6Q2... instead of 6Q1... Both motors same part number?

Dremmeled slots in them and used a big flat screwdriver.

Sorry, I was working on one of our cars. I meant the part number on the outside of the motor, 6Q1959801F, I think for those two cars?

What year is the car? Mk2 Fabia had at least three different types of window motor depending on year. None of them can be coded. The window switches work by shorting the inputs of the module to earth, mostly via resistors, but directly in one position, so I can't see how you would do damage. Was/is the one you've swapped in identical in appearance and part number? What is or isn't currently working?

Engine bay fuse 9, I suspect. Seems you do have the telephone preparation package, according to car data. "Telephone/telematics 9ZG - preperation [sic] for mobile phone with hands-free system" Not sure how you'd go about uninstalling/deleting that, but you could try simply removing that fuse and seeing if that causes anything else to stay awake. "Whack-a-mole" springs to mind. 😆

What fuse number is this 5 Amp 'phone' fuse? Glad they sorted a fully working alt for you. 🙂
