Don't bother trying to put VIN in, free sites will never do anything useful with it.

An imperfect seal would possibly let a very small amount of unfiltered air into the engine, which nothing would notice.

I don't believe this fault will be related to the airbox at all.

Interesting. There's no such second connection on our Roomster, but I just found a system that looks a lot like the arrangement currently on yours, from a Self Study Programme for the Audi version of the 1.2 TSI of this era. Is there an electrical connection (like the green plug on this image) at your brake servo vacuum connection?

I'll have a look at our Roomster in a bit, for comparison.

Sorry for delay, PM replied to. Looks like you may have a non-standard arrangement there.

I'll start a private message conversation with you in a sec. Would be good to know reg or VIN in order to look up correctly part. 🙂

I'm wondering if there's a different version that goes with DSG gearbox, does your car have that?

The way to get a message to admin is to tap the 3 dots in top right of one of your posts. Then choose 'report post' then select the relevant option. In this case 'posted in wrong forum'. You can then help them out by specifying the correct forum.

The oil can come from elsewhere, wicking along in the spaces between wire strands, within insulation; counterintuitively. Coolant can end up in strange places by the same mechanism. Just thought it was worth mentioning, cos I had noticed oil in the sensor connectors on mine but hadn't thought it would matter, until I saw that bulletin and found that it really does!

VCDS Lite, free download from ross-tech.com plus a cheap generic KKL cable works for most stuff on mk1 Fabia, and even mk2 up to early 2010.

The reason I ask is from recent frustrating experience of a wideband sensor fault on our Roomster. Eventually, I found this, which solved it once I had replaced the worst affected bit of wiring and connector on the car loom side. See https://www.ngkpartfinder.co.uk/assets/Uploads/Sensor-oil-contamination-ver2.pdf

If you have VCDS you can probably see fuel level in measuring blocks of module 17 (instruments). You could then see if that changes if you jack up the rear of the vehicle.

Any sign of oiliness within the plug/socket connection of the oxygen sensor?

Might be a dry joint on the cluster circuitboard, where the input from the sender potentiometer comes in. Not sure if open circuit would give a full or empty reading, but probably one or the other. Pin 15 springs to mind, but memory isn't to be relied on.

Yep. That's how it's sold. I think this design came in with changes in March 2010 for mk2's, possibly earlier.

@becky1357, your strip fuses look like this, I think. How did you go about checking them? Did you prize off the green plastic cover bit? The other power feed is from cabin fusebox #16 I believe, a 5-Amp fuse.

It's not super-clear, but from my experience on mk1 Fabia platform, you have an 8 each side, a 6 each side and two 5s each side?

Go here, use ctrl-f to find the various pages for 'assembly carrier', then pick the right diagram depending on your engine code. The bolts may be the same for all, dunno. Car Parts Catalog - LLLParts

Our 05 Fabia doesn't, but you may regard that as something silly. This thread revealed a much more recent Skoda example: https://www.briskoda.net/forums/topic/529835-missing-anti-theft-fuses/

Would need to know the VIN to check. It may well be that some markets didn't fit an alarm as standard, but it would surprise me a lot if no Octies at all had alarms over that period.

I wouldn't be afraid of re-using the existing bolts, if this is the first timing belt change. I wouldn't be so happy to use them again if I knew that they had been out and back in again once (or more) times already. A Skoda dealer may be not as expensive as you think for these items, for example, for items 18, (19) and 19, the recommended prices in the UK are about £2, £5, £3 each, plus tax, so for the quantities required of those ones, you would expect to pay about £23 including tax at a UK Skoda parts counter. Approximately £12 for the 3 horizontal ones; if I'm correct about those.

Not surprised you were finding it hard to identify the correct items. Not super-obvious even with VIN filtering. The ones labelled 4, 6, 7 in the top part of your diagram are easier, corresponding to items 18, (19) and 19 here: The horizontal ones attaching console (20) to engine are a bit more confusing: Slightly less weird when you notice that items 20C and (21) are the same part number. If there are three screws (item 2 in your image) with two long and one short, I guess you have to get two of the M10x75 and one of the M10x55mm? The greyed out items don't suit your VIN.

Excellent, thanks for showing us the damaged area.
