My own 1.6TDI with same mileage as yours (very close) behaves same. Soot good No indicated faults in engine Yet it tries to do regens frequently, so it must be ECU making these requests often to make exhaust not clog up with too much soot. The only common factor is exhaust is nearing end of life, so the car will be performing more frequent time/distance fail safe regens (where it totally ignores soot values!) This is my own understanding, you could to test reset the exhaust to 0mg of oil ash, and then see if the regens stop being as frequent... this will then let the car revert to soot based regens as priority, and increase the time/distance regens. Hell, I will probably do this with my own, as it tries to regen 9/10 journeys, and has put exhaust lamp on... and the soot is low.

MEN2_EU_SKGPx_P0080L_MU8755.7z This should be the correct file for the software train. SD Card in FAT32? Are the files in the root of the drive, and not in a folder called "MEN2_EU_SKGPx_P0080L_MU8755"

If you are driving down a motorway, but not above 2,000 rpm (or what the car needs) then after 60 minutes it will put on the exhaust lamp due to "failed" regens. Just today I drove down at least 15 miles of motorway above 2,000 rpm, when I got home it was still trying to regen, they are strange how they act. Your exhaust is getting very near end of life, so it is going to be doing regular regenerations to try to keep the soot from blocking and then you cannot do any regens at all. I think this is normal as the exhaust gets near end of life, as in early years the generations are less (this is how it seems to me)

Soot is coming down nicely, I guess you will probably need to budget for a new exhaust, or cheat and tell the car it has a new one fitted.

See if you can find anything on time/distance since last regen. Mine even put the exhaust lamp on the other week, but soot values similar to yours. They have many fail-safe features, soot calculated, and also time/distance since last regen.

Have you access to any diagnostic tools? VCDS or similar? Wondering if coding has gone wrong, or the radio has lost a fec/swap code that perhaps enables DAB.

As above, best post the information @pab567has asked the other person for. You can try to hold down menu/setup button to see if you can enter engineering menu if lucky, to get information out of the radio.

I will send you a link now for update

It will be interesting to see what you can find out with your new VCDS cable, might be an idea to so a full car scan and post up the log (can see the firmware loaded for engine ECU) you might find the car has had the NOx emissions fix, I am sure they regen more afterwards. The oil ash reset should only tell the car it has a new exhaust, it's always been an estimate of how much based upon what VAG have done in their testing. I don't see how resetting oil ash mass would have an impact on the Soot calculated though? Rolling back to a pre-NOx ECU version for sure, they cheated a lot despite their claims to the contrary.

If you have a multimeter, the best way to check is in the morning before you start, also can you take picture of the battery iteself (or tell us the type/rating) I replaced my 2015 battery as it was nearing the end of it's life, showing almost 12V when left for a day (it should be higher) I was getting a few lazy starts on a 1.6ltr engine, not massively so, but you could tell it was thinking about it more.

Your car was able to complete the active regeneration before getting home, which is why your fans weren't running and revs were in the normal range. The car is in the majority of the time trying to do active regens, I guess you maybe use the car for shorter journeys?

Well I can send link to 0480 via PM, and you can load it on.

There's update to 0480, when you say just brought it, do you mean car or replacement radio?

Yes can send MST2_EU_SK_ZR_P0369T version if you like via PM

That oil ash comes from material in the oil that cannot be burnt into smaller particles. The value for your car is nothing to worry about, wait until you get to 230k km and measure again then, and every 30k km after. The higher the value, the more frequently the car will try to regenerate to maintain health. In particular, your soot measured is lower than the car thinks, so is a very good thing, sign of a healthy DPF.

S00.1000.17.99 release = "MHIG_EU_SK_K1552" MUVersion = "0411" I will send you a link to this update

At around 230,000km the car should have the oil ash mass read out, then every 30,000km after. This is the material that cannot be burnt off, and as the exhaust gets closer to the limit, the regen frequency increases as it's more blocked. The other 2x values that you should read is Soot calculated and Soot measured, when either one of these reaches 22g, then active regens will take place. As the name implies, one is measured by the DPF differential pressure sensor(s) and is a physical reading, the other is calculated by time/distance and won't read the same as your measured (think of it as a failsafe) When you get your VCDS, you should measure the values of the 3 MVB's (Measurement Value Blocks) If the soot values are near 22g, then perhaps you should do one more static regeneration to get a baseline of what's going on. I found that my Soot measured didn't go under 15g during regeneration, so had to abort it. I then took it to a friend of mine, and at his garage we put in some cleaner, and then after this the Soot measured dropped to under 1g. When you do the regen with VCDS, you can open up MVB's during the process, so you can bring up Soot measured, Soot calculated, then you can bring up measuring blocks for exhaust temperatures. Sorry for the poor screenshot, taken on phone not PC

I will send you a PM for version 0490.

I will send you a link via PM, odds are it's the correct file.

AFAIK only the car's with stop start will have the gateway coding.

Quick way to tell is the stop start cars have an extra connection on the negative pole/wire.

I have 0465 and 0490, not sure if it accepts downgrade, but I don't have 0435 to roll back that far. Try to adjust as much as possible, if not we shall have to try these alternatives.

Just to remind you, that this is the correct screen to update firmware.

I did same, looked at ETKA superb and no DQ500

Can confirm, this is the way.
