rear wiper wiring route .......
If you share either the reg number or VIN with me, I can dig out the wiring info for the rear wiper.

Fresh air - no airflow - Octavia 2013 2.0GDi VRs
Is there a removable piece of trim at left-hand end of dashboard, visible with door open? That may give you a view of motor and cogs.

I didn't look that closely at the parts diagram, which doesn't even show the flaps, but I think there's only one motor up there, yes.

Pressure sensor or not ? Glow plugs
Yes, assuming cyl 3 is the one that has the special plug. Part number is 03L 905 061G, superseded by 03L 905 061L. Latter is £138 + VAT at Skoda, for reference.

Be aware that there is another version of the cabin A/C stuff, Denso rather than Valeo, which has a separate diagram page, with different part numbers. Denso version I seem to remember that knowing which system your car has is not totally straightforward, and probably involves looking at the part number label on e.g. the blower motor. You probably won't be able to with that motor fitted, or not without damage anyway. See if you can see it first!

Recirc flap motor is above the pollen filter, shown in the diagram here as item 18. Diagram shows a LHD car, so in RHD it is probably at the left/passenger end of the dash instead. Possibly accessible via a removable end section? Car Parts Catalog - LLLParts

Yes, I think so. Not sure where I would start on that one though. Does it keep happening each time you switch on ignition?

2008 Mk2 1.2 HTP - Reviving help
If it's like most VW-group connectors, pushing the whole housing firmly onto the mating part while lifting the latch usually helps it release. Once you hear it click, stop pushing and start pulling. The relay in position 4 is the X-contact relief relay. This switches off various things when the starter motor is energised, so that maximum power is available. I think you will only hear it click just as the starter is energised, and then just as it stops being. (Never tried though, so that's theoretical). I suspect the problem you are having may be that the coil of either the ECU relay (position 13, number 429; or the fuel pump relay position 14, number 53), is not being energised for some reason. If the ECU relay isn't being energised, the fuel pump relay can't be either, because the engine ECU is controlling it's coil. Check fuse 3 (5 amps) and see if the terminal labelled 6 and/or 86 on the ECU relay holder at position13 gets 12V when the ignition is switched on. Do the same at position 14 for the fuel pump relay positive coil feed. Again with ignition switched on, but this time it is the terminal labelled 6 and/or 85 that should have 12V.

One way to test the wiring from fuel pump relay to fuel pump, is to link the two bigger connections (30 to 87) of position 14 in the relay holder, with relay not fitted. That should make the fuel pump run for as long as the link is there. But running it for 1 second will prove wiring OK.

2008 Mk2 1.2 HTP - Reviving help
Try another fuel pump relay if the wire paths seem OK. Just because a relay clicks, doesn't mean it definitely works. The contacts can be badly burnt so that it doesn't carry enough current. Judging by one of your photos above, it's the one with 53 written on the top of it. The lack of fuel pump action when opening door may be an unrelated wiring fault, meaning that the vehicle voltage control unit (which senses door opening and triggers the fuel feed relay) may not be sensing that the door has been opened.

2008 Mk2 1.2 HTP - Reviving help
You will just have to work with Jocko's diagram, checking continuity of wires between the various points, especially fuse 30 terminal to fuel pump terminal (the blue/white wire path). Take out the fuse, use meter on resistance range to measure from pin of blue/white wire at pump connector, to each side of fuse. One side of the fuse position should show zero Ohms to there. You may need an assistant and possibly an extended meter wire. The brown/violet wire at the fuel pump connector should go to chassis/earth.

2008 Mk2 1.2 HTP - Reviving help
Your car was built on 1st October 2009, and has CEVA engine code. The circuit relating to fuel pump and the two relays involved is exactly as in @Jocko's post a few pages (and months) back. So fuse 30 is the correct one. Actually a much clearer presentation of the involved circuit than the manufacturer's own diagrams. Is that from Autodata? Do you get fuel pump activation when you open the driver's door for the first time? If you do, that would confirm that the wiring to the pump from the fuse is OK.

Coolant level sensor not working - replacement impossible to find?
It's built into the expansion tank, so you just replace that if you have ruled out wiring faults. Do you get a warning if you run engine with it unplugged?

2008 Mk2 1.2 HTP - Reviving help
These three are the main ones to focus on. I think the one you have with an 86a terminal is probably the engine ECU relay from position 13, which has a diode between terminal 86 and the coil but not from 86a to coil, explaining your measurements. Fuel pump relay, which is the one that may not be OK, is in position 14. Fuel feed relay in position 10.1 is the one that provides a short run of the fuel pump when the driver's door is opened, after the car has been unopened for half an hour or more.

The only way to know 100% what these relays do is to know the VIN and the position it is/was fitted in the relay panel.

2008 Mk2 1.2 HTP - Reviving help
Can't you just write the number on a piece of paper, instead of attempting to photograph it?

2008 Mk2 1.2 HTP - Reviving help
Yes, can see it through the windscreen. Low down. TMB....

2008 Mk2 1.2 HTP - Reviving help
Can you supply the VIN for your car, so that I can find good wiring info, including relay positions, please.
-
2008 Mk2 1.2 HTP - Reviving help
30 is permanent power in, 87 is power out to load, 85 and 86 are the coil which needs to get 12V across it before you will hear any clicks. 85 is low end of coil, 86 high end (but might be the other way round, see specific circuit). Google is your friend.

That's a left hand drive car. I would expect everything to be mirrored for right hand drive.

Did you tell me VIN info already? If I have that I can find fuse info for you.
-
2008 Mk2 1.2 HTP - Reviving help
I'm not sure. Someone reading this who owns a mk2 Fabia can surely tell us where the relays are?? I've tried searching the web with no success, surprisingly.
-
2008 Mk2 1.2 HTP - Reviving help
When you say you opened that side, what did you open, exactly? Relay panel is probably somewhere under steering wheel, behind fusebox.
-
2008 Mk2 1.2 HTP - Reviving help
I think relays will be on same side of car as steering wheel.
