Again, you might be chasing ghosts, at least on CAYC one will for sure end up with ash mass measurement exceeding limit after enough mileage and regens even if the DPF is empty of ash altogether, it is just a calculation in the ECU that does not take into account DPF pressure measurements at all. Or in other words, if you make a 300 regens and drive 100k km, the calc could be e.g. num regens x 0.1g + num kkm * 0.3g (I pulled numbers out of thin air, just like the calc in your car's ECU) resulting in 60g ash mass "measurement" even if in reality there would be only 15g-20g ash in the DPF at that point. Conversely, if you use poor quality, ash generating oil or if the engine burns a lot of oil, you may find clogged DPF while the ECU's "ash mass measurement" shows 20g or less, as in fact quite a few people have experienced. May I ask why you are chasing after this number? Are there any other issues with the engine to even be looking at ash mass?

Hello everyone, first post, but long time reader! I love my Octavia mk3 facelift, yet find myself yearning for the steering wheel that's in the Superb mk3 facelift. The buttons and feel of scrollers are so much better. Coincidentally, I saw some posts on instragram recently of various versions of this. I wonder if anyone here have experience doing this retrofit? I have a heated steering wheel and don't need any paddle shifters, so I think its "just" the button mapping? I've seen posts swapping between old and new superb steering wheel, but couldn't find any for a superb --> octavia swap. Ideally I would hand this work off to someone who knows what they're doing 😂, but I am not sure where to look. I live in Norway, but could do a trip to Sweden possibly if some shop could do such a conversion. Any norwegians or swedes got some suggestions of where to start looking?

@travs mine feels like new car now. In the end i went back to original bottom arms but also replaced my droplinks on the front. I went for 034 Motorsport dynamic+. Not cheap at £225 for pair, but the built quality and feel of the car is totally worth it 😊

Many thanks. I will get the garage to look into that. Strangely enough, the heated seat stopped working about a month before the power drain started

I managed to obtain data from two 2.0-litre engines. 181000km - 55g and 130000km - 47g. The CXXB is now the main suspect.

Not sure what the exact calc for ash loading is, but it involves both number of regens and mileage. What's the mileage on each car/engine? In any case, if there are no signs of restriction in the exhaust (power loss, increased fuel consumption, regen completion issues etc.), the large amount of "accumulated ash mass" is just imaginary, there is far less ash in the DPF in reality. It is just a number / counter in the ECU which by the way can be adapted to a smaller value with VCDS, at least on earlier engines like CAYC. I honestly think that ash number was just put there to cover backside in case of clogged DPFs over the car's life, and also to force replacing DPFs latest at a certain mileage / after certain number of regens or both. The correct way to evaluate amount of ash would be to measure and average pressure loss after completion of each regen and indicate that DPF pressure loss post regen is getting on the high side, but my guess is that given varying temperatures and gas flow, the exhaust sensors used for it are either not accurate or not reliable enough, especially after many years of use / high mileage.

We don't use our Karoq much between trips to the continent. Last time we went in June/July we got the update message virtually every day. There ws never a message to say updated complete. The only odd thing I found was that at some time the settings for the cruise control were changed, causing me some concern, but that was soon corrected. We have just returned from another trip when again we get the message virtually every day, someimes more than once a day. Always accepted but nothing else. Having reset the headlight aim in the Channel Tunnel train, and gone back into settings to ensure the change was actually set, when I came home and tried to set back for UK, it was already on left side running. Whether the 'updates'had reset something in both cases, who knows. We had l Iittle need of headlights apart from tunnels, but I did do two or three ~10 mile trips in the dark and nobody flashed me! I would like to ask my agent but while away I received an email saying that, as of 30th September, ie Wednesday, they are no longer Skoda agents and service is being transferred to a local VW agent. Great! So what to do next? Had an MOT booked but doesn't look like that will be happening!

Hello and welcome Scott Gaz

@Evolution13 that's a spammer, see link inserted into quoted text. Reported.

Bumping old topic but this video extremely useful in having an idea on best way to get door apart and give maximum length of loom to work with. Not a job for the faint of heart or unsure with electrical.

Hi, I've been on Briskoda for just over 4 years but on the Superb forum. Tomorrow I am getting my 2026 Karoq 1.5 TSI SE L Edition delivered. 3 Months old ex demo, so will be on this forum now a lot, to learn about it, and perhaps contribute a bit.

Best of luck with it!

Well, been on here for over 4 years now, contributed some, and learnt a lot more. But time to say goodbye. But not to Briskoda, just this forum. I am getting a 2026 Skoda Karoq delivered tomorrow, so will be migrating over to that forum. Thanks for all advice given here, it's helped a lot.

Could this 60g be a natural occurrence? The worst-case scenario is that oil gets into the DPF. If the 60 g is a value calculated from the regenerations, it could not have accumulated from the normal regeneration cycles. It is currently regenerating every 350 km.

Yep, another Autodoc never again here, on ATE Ceramic brake pads in my case, but fortunately sold them here to a fellow member.

Why? If valves are not stuck all four ways it is easy. I did not do laptop magic. Just gravity. Blocking pedal in down position is important. I would check if cable allows to connect another pump or look for extension on ali. Maybe brushes in motor are dirty, worn. Probabbly circuit sensing too much resistance or intermittent power supply.

I have the Solution and dont need help

DPF ash load primarily depends on mileage and the number of regens. While it is possible that on EU6 engines it is measured / derived from DPF pressure loss after regen (doubt it), at least on our 2012 Roomster's EU5 1.6TDI CAYC 105bhp engine the ash load is simply calculated and increased based on mileage and number of regens, no measurements involved. If you experience frequent regens, you will find ash load going up quickly even though there is no change in pressure readings around DPF, i.e. no actual ash.

Hello everyone I am new here. In the process of buying a 2012 5J Fabia RS Estate (We call them Wagons in OZ) looking to get some info and share my upgrade journey. I am a bit of a car collector/ hoarder with a lot of JDM and Euro oddities Regards Scott 3SpeedScottie

@mpg_cloud @Cairus If you need to update to version 0480 and activate CarPlay, send me a message.

Specifically, I am referring to this part I’ve marked in the photo.

I have the older Mk4 Octavia, so unfortunately I can't help you. But I wanted to add that disappearing functions from the infotainment menu is a problem which is suffered in the Mk4 too. Skoda really need to invest in some decent software techs

I’ve had a 2026 Octavia Sportline (1.5 TSI) since August. The configuration option on the Virtual Cockpit display—used to add or remove data—has disappeared. I’ve reset the infotainment system, but I still haven't been able to get that function back. I’m attaching a photo showing my hardware and software details. Can anyone help me?

Is this the kind of upgrade that you can tutorialise?
