Sorry, wasn't trying to alarm you with reference to compression, it's just a quick and easy thing to eliminate if you have a tester. If you get a fault code for the same cylinder, consider moving that fuel injector to a different cylinder to see if the fault moves with it.

Read the fault codes again, as a first step. Do you own a compression tester?

There will be a sticker on it somewhere.

Items 10, 11 here https://skoda.7zap.com/en/cz/fabia/fab/2003-225/4/411-411010/ I use this ebay seller quite a bit https://www.ebay.co.uk/itm/Genuine-VW-Audi-N90954802-Front-Hub-Strut-Pinch-Bolt-Nut-Kit-Golf-Passat-A3-TT/183142374830?epid=12022526006&hash=item2aa422ddae:g:84MAAOSw4LJbp4-k

No, see here: https://www.opieoils.co.uk/t-multi-grade-car-engine-oils-explained.aspx 100°C is the point at which the right-hand number is measured. "Winter" and "summer" would be too vague.

Cheers for the input. Looking at the numbers on the graphs for the lower viscosity oils, it does appear that @brettikivi is about right.

No worries Mike.

Black/blue wire is feed from switch, brown is earth.

A continuum, surely. @weasley would probably be my go-to person for knowing where to find such info.

For the diesel, consider creating an account on either fuelly (https://www.fuelly.com/) or spritmonitor (https://www.spritmonitor.de/en/) to keep an online record of all your mpg data. Using brim-to-brim numbers would make it much more 'real' than the day-to-day observations of trip consumption figures. At least with fuelly, and probably with the other one, they do a little signature thing so the current average is constantly displayed with every post you make. For someone so interested in this parameter, it would make sense to do this, I think.

I'd predict that the symmetrically positioned light on the offside is the rear fog? In which case just one.

You don't seem to be wrong according to ETKA. Electromechanical power steering I see diagrams for. Electro-hydraulic I don't. e.g. here: https://skoda.7zap.com/en/cz/citigo/cit/2013-727/4/

I would start here: And then inspect the brake servo vacuum hose carefully.

It'll be interesting to see the numbers on the emissions report if you wouldn't mind letting us know.

NO

If you own a soldering iron, I would suggest re-flowing the solder joints of all pins of both connectors on the instrument cluster circuit board.

I'd be really, really surprised.

I shouldn't think there are many people who've tried it, and even fewer who could say for certain what would've happened differently if they hadn't. Why not just try it and see if it has any effect on oil usage rate? If it doesn't, no point in continuing, if it does you'll have some data to work with in your decision about the next oil change.

What did I do?

I would suggest one that meets 505 01; and please let us know how it goes.

Glad you got there in the end. And good on you for closing out the thread with the relevant info.

Did you adapt the ECU to the new EGR (either time)?

It's far from obvious to me looking at this diagram, but maybe you can match up what you need with the real bits and pieces in front of you to look at: https://skoda.7zap.com/en/cz/octavia/oct/2002-252/1/199-199020/
