All those plastic parts are unique to the Superb. All black interior sounds horrible though, oppressively dark

Brake lights are already plenty bright enough. This would blind drivers behind you, especially at night. You would also lose the fog lights for their normal function.

Even bi-xenon headlamps on these cars have an extra halogen bulb for high beam as well. This one is also used for headlight flash. If your car has auto levelling for the lights, you should see a little plastic linkage on the lower suspension control arms on the (I think) left side of the car. I doubt that xenon units would have been swapped for halogen - it would end up nearly as expensive to buy two halogen units as a single xenon one (more often than not you are only changing one due to damage). There's also the hassle of getting a basic halogen to work on an AFS equipped car, or disabling AFS, plus having to change the wiring harnesses. It's not simply a case of unplug one and plug in the other. The main telltale for xenons is that the light is much whiter than halogen. You'll also notice a slight delay when they are switched on and it will take a second or so for them to reach full brightness.

XL applies by default to certain profiles because there's so little sidewall to support the car (I can't recall offhand what they are). A while back I summarised the OE wheel and tyre info from the service manual in this thread: https://www.briskoda.net/forums/topic/445067-superb-2-wheel-and-tyre-information/

A gearbox repair/replacement will cost multiples of the cost of the oil change. As above, the oil is shared with the clutch pack and gears, so even on the motorway it's still getting a workout.

Have a read here: All available information on OE fitments is in there.

The diagram in the manual is for LHD cars. RHD is mirror image of it.

Some of the info in this thread might be useful to you, I suspect the Fabia is using an older generation cluster. https://forums.tdiclub.com/index.php?threads/99-5-cluster-rom-documentation-thread-applies-to-all-pre-2k-a4-non-nb-and-passats.327737/

The bi-halogen uses a single bulb for high and low beam, using a shutter to switch between them. There is no space in that housing for another bulb. At least some vRS models got a unit with projector low beam and a separate reflector high beam but that was only on that model.

For the sake of completeness, I get 300-400 km between regens during heavy load driving, and my car has had the emissions update.

If you're doing a lot of urban/suburban driving then it's pretty typical .

The MSDS for it is at https://www.partinfo.co.uk/files/COSHH-MSDS Information/Dipetane/Irish MSDS for Dipetane.pdf Unfortunately it's not very helpful in identifying composition (sometimes the MSDS will list key ingredients). The thing that's always made me suspicious of this stuff is their claim that it works with petrol and diesel. Given how different the fuels and their respective combustion cycles are, I doubt it's any use since optimising for one severely limits its functionality in the other.

Towing a 1.4 tonne caravan, I've gone 400 km between active regens if VAG-DPF is to be believed. In normal driving (mix of urban and motorway) it goes 150-200 km between active regens. Ten minutes and it's done.

It actually does. I can't say I'm a fan of it, but there you go.

I've just put B6s on my Porsche 944 and they're pretty stiff. Not sure I'd like them on my Superb at all. If you're on 18" wheels I think they'd be unpleasant on all but the smoothest roads.

Like I said, you could be getting a lot of unnoticed regens while you're on the motorway. A regen only takes 10-15 minutes and could easily pass unnoticed while you're cruising on the motorway. More than likely it is regenerating at regular intervals, you're just not noticing it most of the time for the reasons I've just stated. The telltales are really only noticeable at idle or if you shut down during or just after a regen. You don't need to be on the motorway for a regen to happen either, it'll happily regen while you're pottering around town too. It sounds like your car is functioning normally based on what you've said, there's no need to do anything to it or put anything in it other than fuel.

How often is this happening? Normally regen occurs every 200-400 km, depending on driving conditions. More often than that might indicate a problem. If the regen starts and finishes during a motorway run, you'll probably never notice it happened either.

Looks like Rosso Brunello.

You don't need starter fluid. It's a case of going through the intake system from the MAF sensor down to the engine and checking that everything is fitted correctly and there are no cracks or holes anywhere.

Check for leaks in the intake system. If the airflow is unstable it can cause all sorts of trouble.

This thread was where I got most of my info: Head unit is the standard Columbus unit.

Highline reversing camera. DIY raised boot floor. Towbar.

The service manual lists all of those settings.
