I didn't update my previous Superb post recently but my car is 2 years old now and booked in for the 60k km service next week. The oil consumption is still high but has remained constant at ~1L per 7000km. The garage will again check for signs of oil in the usual places but I assume they will say all is fine & higher consumption is normal with this engine & 0W30 oil.... They suggested that going back to 5W30 might improve the situation but advised against it until the warranty was over in case there was really something wrong which I wanted to claim against the warranty. As the car is running fine, I will probably stay with the standard oil. I've found it around £40 for 5L so pick up a tub each year I come back to the UK. My fuel economy is good for the DSG 4x4 (5.8-6l/100km) so I'm happy to accept the explanation of the dealer so far. Gabbo

On our last Volvo XC90 the high been assist was "always on" by default... It was a pleasant suprise that the superb system worked just as well

I think the behaviour you have is normal for the Superb with standard suspension without DCC unfortunately. Mine is from 2023 & I have 3 big speed bumps outside my house. At low speeds it's like being in a bouncy castle, midspeed it's not as bad and a bit faster feels like you bottomed out the suspension when you enter or leave. I also have the same kind of creaking noise from the front suspension when the weather is cold & I go over the speed bumps. It disappears when the car is warm but comes back el again each morning. I had the same creaking noise on my Octavia after around 7 years & was a bit disappointed to have it on the superb after 2. Usually when I take the Octavia for a service the garage greases something and the problem disappears until the next winter. However for the Superb, I'll be asking them if there's something better they can do under warranty.

The Columbia music playing issue

I did this with my Octavia because I had a complaint that the MIB1 always restarts playing the music from the first song on the SD card instead of remembering where it was. I had firmware updates for 5 years instead of only 1 year with my warranty because they were still trying to fix it. Unfortunately VW never came through with a correction though. It was a common fault it turned out

I would book it in to the dealer before the end of the warranty. Even if they say "no fault found" you have a service record entry which says "owner complained of driver/lane assist warnings in the rain" during the warranty period so can argue that the fault existed during warranty so they should honour any repairs afterwards. I have driver assist on my car and I've only had the systems disabled when in roadworks with high temporary barriers and when driving in winter and the windscreen was smeared with salt solution I'd failed to clean with the wipers. Each time it was only for a few second and cleared itself afterwards

They were Borbet V wheels I think. I didn't noticed any rough finished or had any problems with them. They are also homologated for the Superb so I received the type approval certificate with them for the Swiss TuV for free. I got them from one of the big online sites, delivered with fitted tyres but can't see to find the emails from my order at that moment.

Your driving profile should be fine for a DPF, lots of motorway mileage

I would check for an air leak in the intake and exhaust. This can cause the combustion to create more soot than normal and hence trigger the warning that regen frequency is too high. Effectively the regenerations are working as intended but the DPF is filling up faster than expected. It would require longer term monitoring but it could also be a clogged/fault delta pressure sensor giving the wrong feedback particularly if the fuel economy is still fine & didn't change.

I agree with @fr1nklyn s diagnosis. With 350k km on the clock it's quite normal that the DPF could be full with ash rather than soot and a regen or additives won't be able to fix this. There are places you can have the DPF removed and cleaned of ash but I've never owned a car long enough to have this done so have no opinion if it's cost effective

You will find any SKoda Official wheels will be very expensive compared with aftermarket alternatives. You can get nice looking aftermarket wheels much less than €100 that look great and as they are cheaper, you don't need to worry about dings and scratches. These are the 17" wheels I got for the winter here which were ~€800 for wheels & premium tyres (Conti Wintersports)

If you download the wheel and tyres brochure from Skoda directly they also provide this information. This will give you the officially homologated rim sizes and compatible tyres. In the UK I think you can still fit any tyre size you want to the car even if it's not matching the official figures. However in many countries in Europe, you will not pass your MOT without official work and tyre sizes. I'm not sure how the snow chains law work in Austria or France but you can also consider the hybrid chains (socks with plastic chains) which are much thinner and will fit into the slightly tighter places...

I have a 200PS TDI 2L from Nov.2023. My car consistently uses 1L of oil each 7000km. The first 3 times the dealer refilled the oil, checked there were no leaks and we were monitoring the situation. According to them, it's within VW spec so unless it gets worse VW won't do anything. I'm now at almost 60k km and it has stayed constant at 1L per 7000km. Min->max on the dipstick takes just about 1L. My 2014 Octavia TDI will do 30k km and use less than 0.75L of oil. They suggested it's due to the change in oil from 5W30 on older engines to 0W30 on modern ones but as it's under warranty they will not allow me to change. As it's constant I don't mind topping up regularly & bought 5L of Castrol Edge for £35 to keep it topped up between services

Thanks for your inputs. My car is a keeper but basically a motorway cruiser so light use. I think I'll ask them for the DSG service and Haldex (if they will do it). I have another 2 years of manufacturer warranty but I'm all for preventative maintainence rather than repair.. One of the reasons I asked about the DSG service was i have the feeling that some of the gear changes are a bit jerky sometimes and not as smooth as before. I'm always very light with the throttle and mostly drive with ACC active and was thinking a service might get it back to the sweet spot. Gabbo

My 2023 TDI DSG 4x4 is coming up to it's 2nd year 60k km Service... I'm assuming it will need some sort of DSG service? What about the 4x4 is there anything to do? Is there somewhere I can see what to expect the garage to do? Thanks in advance, Gabbo CH

The top choice for OBDII standard will give you the standard fault codes required by the legislation but will miss some codes which are manufacturer specific to your car. You should still get a code but perhaps won't get a description of the fault & will miss other items from live data & ECU information like coding. As you suggest, selecting the correct engine will give you access to more information...

What do you mean by preheating unit warning light? Do you mean the glow plug light? Was it fully on it flashing? If it is flashing it usually indicates problems with the glow plugs, however, this lamp is also commonly used for non emissions related engine faults. You really need someone to read the fault codes properly to be able to make a good diagnosis of where to start. A Bluetooth OBD dongle which you can use with a free app start from around £15. A good investment from my point of view even if some learning is involved for hire to use it. If you paste the output here, people will be able to help you more easily. Gabbo

Obd11 was advertising on it's website that it can support SFD codes automatically by connecting to VAG Servers. Not sure if this would expand to new features but you can understand why manufacturers would prefer to secure these features so that they can lock them behind a subscription paywall in the future.

I had a look at the Octavia forum & was surprised for the MK4 there's not a pinned thread for "tried and tested adaptations" to use with vcds/obd11. Perhaps the newer cars have some kind of protection making it more difficult to change the configurations/coding

@nicknorman changed this in his 24MY Superb MK3... I think there's another thread here in the superb section with his information/coding.

2025 as in a MK4 Superb?

I recently replaced mine on the Octavia (non pressure sensor part) and it was straight forward enough. I changed only number 3 iirc. The others would have been more tricky to get access to without a very long drive and perhaps universal joint. It seems the golden rule is don't over tighten & don't feel the need to turn an extra little bit as that can overtighten the plug making it difficult next time.

I think it's this one: https://www.skoda-parts.com/spare-part/03l963319d-glowplug-tdi-cr-skoda-15152.html And this one with a pressure sensor: https://www.skoda-parts.com/spare-part/03l905061m-glowplug-with-pressure-sensor-skoda-23614.html

If you replaced the battery with the same type (AGM Vs EFB) & approximate size it doesn't really need coding... I changed the battery on my Octavia myself (Same AGM type & 3Ah larger) & didn't recode anything. Stop start & all other functions worked immediately without any problems. After 4 years the battery is still going strong. To solve your issue, you need somebody with some basic diagnostic tools. I would say it's worth paying a Skoda or VW garage the price for the investigation even if you end up replacing the parts yourself... I would says it's still most likely an ABS sensor signal problem (next thing would be wheel hub with the magnet elements) or perhaps Cam/Crk sensor problem (more likely for the OPs issues). Gabbo

So I figured out why I think the icons on the virtual cluster have changed... (I'm not going crazy)... The settings of the virtual cluster were lost with the update.... Previously I had the Driving assistance info as one of the main entries in the in the big circles. Now it was only gear and speed. When you put the driving assistance in the main display, the mini icon in the bottom center of the display disappears (this new icon after the reset was one of the things I'd noticed has changed). Have now put back the virtual cluster settings to my liking so all is good 👍
