There's no other update, this is latest version released. Is your map on a genuine Skoda memory card?

The two items in the middle J02230 & J02250 were used.

Probably to 0369 version, but you are in wrong menu for update. Hold down Menu/Setup key for 10 seconds to get hold of your Software Train (and this location has the update button)

https://www.briskoda.net/forums/topic/508126-2019-mk3-sudden-high-idle-problem/ A more recent thread, if it's GPF/Otto Particle Filter, then it can rev to around 1,450rpm, and would explain the extra power as the fuel input will make the car acceleration greater.

Down pressure sensor hole before the DPF. My soot was stuck at 15g, then dropped to under 1g after treatment.

Yes the soot can be burnt off, which is whole purpose of a DPF, and it can be "fixed" with some products as was in my own case. Oil ash is oily stuff that probably can be partially washed away with chemicals no doubt, but not sure if it can be fully cleaned. Other who have removed DPF for this have poor results (probably the Platinum itself is worn out, or coated in sticky oil ash residues)

Nope, same as inside my car.

There is a process that I do not know how to do where you can swap from 02xx to 03xx or 04xx. But the risk of creating a broken radio is high, and to recover is to open radio and boot radio on bench with wires connected to chip(s) on the circuit board. I wouldn't recommend it unless you can recover situation. Maybe @pab567would be able to perform task if you removed and posted it away? Or perhaps he can guide you remotely in process, and be able to recover if it breaks.

@stefansuperb3@vektors are you still awaiting firmware updates? @Phil82if you're new then you won't be able to edit posts until you have written 5 or 10 posts. I will send you a PM for 0480 version.

Well I do have this available then if you wish to try it.

Soot comes from the unburnt fuel leftovers. Oil ash comes from the oil that slips past the piston rings, and the particle size is larger and cannot be burnt off, this value is only estimated from the ECU calculations, a car that has wrong oil, or consumes more oil than average car will have a much higher real value than what is seen on readings (this cannot be measured) Your car does have more soot than the car thinks it should have, but this happened to me recently where it was reading 15g measured (after trying static regen) So a friend I know put some product into the DPF and the regen was able to bring the soot back down to under 1g measured (this comes from too many short journeys before I brought the car) Mine now wants to regen still a fair amount, but I ignore it because even when it put the exhaust lamp on, both measured/calculated soot was low. Stupid cars. You could replace the DPF if that part is correct (price is very good if correct) and have trouble free motoring. Maybe you can provide some car details into your signature on forum so that people can look up details.

Welcome, I am sure you will learn some good information 🤝

Yes there was the guy whose car was drinking 6l of oil per 15,000km, no way the oil ash values in his car were correct. I am not sure if the calculation soot is above 45g it can block a regen, measured 100% would do. That could indicate a broken DPF sensor (had this happen to me)

I am shocked it is that cheap considering it supposed to have Platinum inside! It's a pity you have booked the car in with dealer's, they will gladly take your money and you won't be any better off. If you have no fault codes in engine, and soot is under 45g, oil ash below threshold, that means exhaust is healthy. The only possible fail is if the live readings are not sensible/logical. Edit: I should clarify by healthy I mean that it's within parameters, doesn't mean it's as efficient as when new.

There is an update to 0480, but usually for big fixes. So don't expect it to fix or add wireless AA.

I don't know exactly where yours is located, odds are behind engine and not under the car. I am 99% sure they are clamped on, but you may wish to check on prices as they will make your eyes water.

You really do need to know your hardware fitted before you put on any random firmware. It would be a good idea to eject the radio from car so a suitable correct firmware can be found.

Some values and information that could be useful to our subject. Once the load threshold of the diesel particulate filter has been reached, the exhaust gas temperature is lowered by the engine management system. This is necessary because the particulates accumulating oxidise into carbon dioxide in a temperature range between 600 and 650 °C. (For diesel fuels covered by DIN EN 590, the combustion of particles is possible at a lower temperature, at approx. 500 - 550 °C, as the fuel contains additives. These additives reduce the required temperature for burning the soot). So better quality diesel will have a lower burn temperature. Here is the image for the 1,000km self-test that doesn't bother about measured values

The value of your oil ash volume is just an estimation, if your car uses more than average amount of oil, then the exhaust will perhaps already be full. The DPF regen process can abort if parameters are out of spec, though the software/car may not specify a reason, did you notice any strange values during forced regen? Temperature too low/high, was the soot levels reading ok, or negative values, was fuel level enough or had it dropped low? As for your long motorway trip, it should have cleared the DPF in that distance, but again it depends on health of exhaust, and as mentioned, you cannot rely on the figures the car presents, they are just estimations of the oil ash.

There are two values I have read in the documents, one states that it stops active regen at 10%, and the other states 15% (the two values could represent CR and then PD engines) What they don't state is what the scale is, now 45g of soot is the game over point, so 10% could mean 4.5g. As @J.R. mentions, if the car was doing an active regen and you turn it off during, then should carry on next time you start. They also do have 1,000km so called "self-test" but they don't mention if this decreases with age.

I only have a working theory of when the Oil Ash is high, and near "end of life" it will increase the regenerations (not due to soot!) just a time/distance one. My own car put on exhaust light just last week, I was home in 5 minutes, and scanned low Soot (both measured and calculated!) So if you tell car it has new DPF, then it should stop these weird regenerations that are not due to too much soot. I am happy to test this, as I don't care about the "trouble" and then I can trust the soot measurements to decide when to regen.

The only way you would be able to know what this was for would be to get hold of the TPI documents, and even then, you might have 3-4 documents for various engine complaints possibly.

http://wiki.ross-tech.com/wiki/index.php/2.0L_CR_TDI#Adaptation_of_Carbon_Mass_.28after_DPF_Replacement.29 You can try this, but don't shoot messenger, this is telling your car you have fitted a new exhaust! I don't mind doing this on my car at all, as I am sure I will just run it into the ground so to speak.

Done, best of luck
