@Edwa That's only a very temporary fix! You clearly have the same issue with many (most?) of the other wires, which will also break soon. You may not like it, but you have to replace the entire loom.

What's the source for the ET45 for 7.5J? The factory-fit 7Jx17" wheels have ET49...

Hm, that's a strange combination. With the higher sidewall on the rear tires, it will tilt the car slightly (lift the rear). This will definitely change the steering geometry a bit as well. Not sure though whether that is the cause of your problems, but I would advise to test your car with four equal tires to see if that changes anything. Have you ever compared your S2 to another S2, preferably with (almost) the same tire dimension and engine?

The S4 only entered the market in late 2024, so you won't find any problems with 2023 models...

@GoneToBeemer Panoramic roof problems never occur on new cars, which an S4 is. You only see them on older cars. So most likely nobody in an S4 already has problems.

@Outfoxed Sorry, no help, but never use a torque wrench to unscrew things. It will ruin your torque wrench calibration. Use the proper tools for the job.

The active TPMS (with sensors in the wheel) is optional for the Mk4 Superb. Most do not have it (and use the ABS sensors).

The satnav update policy of manufacturers is nothing less than ridiculous. Cars last at least 15 years, and providing these updates is technically no problem at all. This is where the EU should step in, by simply demanding updates for such periods (instead of making al these stupid Advanced Driver Assistance Systems mandatory, which only made cars more expensive, and most small cars EOL).

Thanks for the very good report 👍. Inspecting the wire loom at that position should be standard practice when changing the battery. If I had know this I would have carefully inspected that location last year when I replaced my DSG oil (which required removing the battery and the tray below it).

Missing parts: The small tool to remove the plastic caps from the wheel bolts The compressor The tire repair kit (which you don't want since it ruins the tire). Only if you have a spare wheel, than there is a plastic insert in that wheel containing the jack and a wheel nut wrench. I would order a spare wheel and the spare wheel kit if I were you.

Bad Road springs are most likely springs for cars equipped with rough road package. They have a little higher riding height, I think it was 20 mm? If you mount these springs on the rear you also have to mount them on the front side (and maybe also mount matching shock absorbers?)

Me too. But the compression of my 1.8 TSI was also still normal when it was burning oil. I don't think that a compression test is the right way to test the condition of the oil-scrape rings (the lower of the three piston rings).

Oil consumption with an EA888 is 99% of the times a problem with the piston rings. This is usually fixed by overhauling the engine (new pistons + piston rings). How can you be so sure that your engine does not suffer from issues with the piston rings? Has your engine already been overhauled in the past? In that case they forgot something, because normally they also replace the valve stem seals during the overhaul...

Swapping out sensors without knowing what you're doing is never a good idea. First you have to determine the actual fuel pressures, both the low pressure side (between tank and high-pressure fuel pump) and the high pressure side (in the common rail). Both can probably be read by VCDS. If you know which sensor has the faulty reading, you replace it with a different meter. If it still reads too low, you know what the problem is. But remember, when a fuel pump does not produce enough pressure, the fault does not have to be in the pump itself. It can also be a problem in the wiring or the control of the pump.

@VanhireBoys Apart from the adventure story: What wheel and tire size are you running in your Superb? They look larger than stock? Is it 225/50R17 on 7.5J rims? Or 215/50R17 on 7J? Or am I seeing it wrong and is this just stock?

Read this topic?

That's not correct. The 7-speed gearbox coupled with the 1.5 eTec is a DQ200 with dry clutches. The 6-speed gearbox of the PHEV is the DQ400e evo with oil lubricated (wet) clutches.

@persimmontom and @KirkJames : What about the broken bulb message? Many LED's cause a broken bulb error on the dashboard. I recently had that issue when upgrading my high beam H7 bulbs to LED. Do your bulbs generate an error message as well? Or are they just a straight swap without any issues? 2nd question: Many cheap LED's cause DAB signal loss (due to a cheap DC-DC conversion circuit). What are your experiences with these LED's and DAB reception?

That part is from an S3 and will not fit on the S2's in the section of Briskoda.

Your picture doesn't work. Maybe try the universal .jpg instead of the Apple-only .heic format?

It is impossible to answer that question without knowing which brand and type of the aftermarket stereo you've got. Have you already asked this question to the shop where you bought it? And what did the manufacturer say?

@xserces You're posting in the wrong topic. This is a topic about the original Columbus as used in the Superb 2. You have an S3, with a completely different Columbus.

There is already a topic about the location of the alarm horn, and the (difficult) replacement of its battery: https://www.briskoda.net/forums/topic/458298-alarm-siren-battery-replacement/

Answers will be more useful if you specify petrol or diesel...

It attaches to the rails in the boot floor (not standard in every version of the S2 I think). I have it as well, but have only used it a few times in the last 14 years that I owned the car...
