The car is 2010 Octavia 1.6 TDI CR. This morning I was pouring 10 liters of diesel fuel from a jerry can. The can with the fuel had been sitting in the trunk for about 3–4 weeks, sometimes in freezing temperatures down to -10°C. While pouring, the diesel looked completely normal, but unfortunately, right at the end, I noticed some sediment on the strainer of the fuel funnel. It looked like 3 or 4 large rice grains, about 3 cm long. Unfortunately, I only saw it after I had already poured all the fuel into the tank. Should I be worried?

I have a 10 liter canister filled with diesel in the trunk of my 1.6 TDI Octavia. I had it filled once, then I used the fuel and left the cannister closed in the car. There was some small amount of diesel left inside. After 3-4 weeks I wanted to fill the canister again. I opened the canister, TSSSS, a short, distinct hissing sound. Like I opened a soda. Is this normal or is it the possible that the diesel leftover has somehow gone bad in less than a month?

That makes sense. I recently had another regen and if I took to VAG DPF at its word, it started completely out of nowhere. The app showed soot mass calc ca. 16, the percentage thing about 60% and suddenly it just magically jumped to over 24g and 100% respectively and the regen happened. This time it went a bit faster, took about an hour. Happened about 700 km after the last regen, and after about 250 km drive

About that. Before the regen I tried to trigger regeneration but was unable to do so, despite it being pretty full of soot already. It didn't start regen before the percentage in the app raised over 100%. Should it be possible to force regeneration by driving at the right speed and RPM even at a lower soot content, or it will only start regen when the soot contet gets high enough? Basically - am I on the car's mercy as to when it triggers the regen, or can I make the regen happen when it's convenient for me?

The oil ash is less than 5g. From I've read this is a low amount, is this right? Considering the age of the car I'm guessing it was cleaned by the previous owner at some point (?) It still bogs me that it took so long... I mean is it really supposed to last over 3 hours or is there something wrong. I can see only links to the pictures but I can't open them - opens only a grey color with a "no entry" sign.

Many thanks for your answers, unfrotunately I can't see the pictures. My experience continues. Yesterday the regeneration started in the least convenient possible moment. I took the car for a ride but the process turned out to be excruciatingly slow. And the yellow DPF control light turned on about half an hour into the process. After over an hour of driving around I had to interrupt it because I simply had no to time to continue. The light was still on. I went back later and drove for about two more hours. It finished on about 25% and somewhere over 6 soot mass calculated. The DPF light turned off. The indicator in the corner of the VAG DPF (which I guess shows the tempo of soot burning?) varied from ca -70mg/km to over -200. Very rarely reached -300 for short moments. RPM about 2300-2800 most of the time. Altogether the regen lasted for over 3 hours to complete. Should it really go on that long? Is there something that could be done to make it faster? Do I understand correctly that the oil ash level is the thing that does not lower down with regen and has to be cleaned mechaically when it gets too high?

Hello everyone, since very recently I own a 2010 Octavia 2 FL 1.6 TDI. I didn't exactly plan to buy a Skoda, I just looked for reasonalbly priced and reasonalby roomy (but not too big) family car. Having a sentiment for VAG I mostly looked after VW's, ended up with a nice Octavia. As for now I'm doing a lot of online research on how to take care of this engine, as I'm new to having a diesel. For now it drives beautifully and I'd like it to stay that way without major problems.

Hello, since recently I own a 2010 Octavia 2 FL with 1.6 TDI engine. I'm new to having a diesel so I'm now learning how to take care of it. Especially that most of the week the car is used for short distances around the town, with longer ones once a week or two. So here's the thing. I got VAG DPF app, connects it with the ELM327 adapter. Tells me that the DPF is 94% full (I guess that what it means), so I took the car to a highway hoping to initiate regeneration. I drove for about two hours. Nothing happened. I maintained RPM around 2500-3000 (max 3500) for a long way. Nothing happened. No signs of DPF renegeration I could notice. But in the VAG DPF: During the trip the percentage in rose to 100%. Soot mass calculated went from ca. 23 to 24g (measured 8,3). "Field regeneration request status" changed several times between 1 and 3 (I have no idea what that means) The app gave some signs, a red icon next to the DPF image and some sound, so I guess it was signalizing something but I'm not sure what exactly. I drove like that for another half an hour and still I didn't notice anything else happening. As for the app the percentage didn't get any lower, it remained 100, soot mass calculated went even slightly higher, "distance since last regeneration" just went up. So what do I do? Does it mean anything, should I force regeneration (and how becase so far I was unable to do so) or just leave it alone and wait untill the regeneration starts?
