not got the option for static on mine 😭 and the driving one doesn’t work for me so far - hence why I’m looking at other things rather than the DPF itself after multiple attempts (and wasting nigh £200 of fuel driving for hours on the A14, at night, so as to keep revs at required minimum CONSTANTLY 😕🤦‍♀️) Yeah regen doesn’t trigger AT ALL 🤯 even when set to run next ignition cycle - and yes it TRIES to run, takes out of limp mode correctly every time it’s set 🧐🙄😔

FOUND IT !! Definitely helps to be looking for the correct thing and not a totally unrelated item… 143k miles - and unfortunately no idea as only had it since April @ 139K - and started throwing the described DPF faults about 500-600 miles later… according to the ECU however it’s not ever had any faults prior - in other words the seller carefully wiped every log accessible to hide the issue 🤬🤯🤦‍♀️ promised a service was completed the day before my dad picked it up too… dunno WHAT they serviced though as we replaced oil and oil, air and fuel filters the other day and they were proper nasty 😕 currently trying to get access to the damn sensor wiring sufficient to connect meter and test it 😅🥲😵‍💫

mmmmmmaybe 🫣🫡 watch this space- I’m outside for the first time in a week or two today and playing pretend mechanic 🤪 so will see if I can get readings before anything catches fire! fingers crossed 🤭😅🫥

from your description, the sensor I can see screwed directly into the exhaust pipe (it’s after the “fuel go bang - intentionally explody” bits so exhaust pipe by my reckoning lol) at back of the engine bay would be the oxygen sensor then? And NOT likely related to DPF fault? as in that case I’m so glad I asked and you took the time to teach would have been an expensive lesson to learn otherwise 🫣🥹😂 Wilco Roger. Or is that Roger Wilco? Also read you 5x5 and other such amusingly accurate yet pointless in this format radio codes* 😁 again massively appreciate the time and effort spent responding to me in this kind of detail btw😎👍🤩 - J *If you are asking “why?” To this nonsense… I will say only “because!”

but that makes too much sense! That isn’t allowed in automotive design! There could be another hose and coupling that would add a failure point and cost hundreds of beer tokens to replace!! </sarcasm > will provide such photographic evidence as soon as my anxiety lets me go outside to play for a bit 👍🫣 Yay me I was doing it right already! I think. will do it again to be sure though 😁 I should have a stored set of “everything I could find to save everywhere” from before I went fiddling with things - let me know if that helps and I’ll go hunting for it 🤫🫡😅 all the thanking once again 👍😎 oh and you replied again already! Which response also indicates I didn’t break any rules posting my registration, coolio happy days etc 🙃😅🫡

I have no clue how that ended up on my profile tbh 🫣🤦‍♀️ it is a 2010 mk2 Fabia estate, CAYC engine confirmed - 1.6 diesel tdi lump at the highest output of the three available variants (wanna say 105PS but that’s top of my head not checked), registration KN60 EJX (if I am not allowed to post that I apologise, I would have thought that was considered public information as compared to VIN but am doubting myself as I type this!); if you want me to check via VCDS or would like me to send you a picture of the VIN or full code/spec label in the boot floor space or any other way I’m perfectly happy to do so btw!

so if I understand correctly - there are separate differential pressure sensors either side of the DPF and a single oxygen sensor AKA lambda sensor for this particular engine? I’m hearing “find generic or pay through the nose” regarding the price, or is that disreccomended in this context? 🫣 regarding VCDS and stored fault codes, I want to say no but may well be pressing the wrong buttons (ooh lookie so many BUTTONS!! 🫣🤪🤩) so if you would be so kind as to send me exactly what to click/mash/press in what order to get the output you need I will do that and get back to you imminently 😇 once again MANY thanks for your time and kind assistance, it is very much appreciated! 👍😁

Also am I wrong to think the quoted £180 odd for a SENSOR is way OTT or is that normal? 🫣😱

I may well be using the wrong word! I admit to being thoroughly confused between differential pressure sensors, lambda sensors and oxygen sensors… and am not knowledgeable about cars or engines in general at all! My dad is insisting that I get the part numbers and that there should be two. Beyond a certain point I don’t ask more questions and just go along 🤗😂 Please do by all means teach me as appropriate if you will - assume I have near zero practical knowledge but extremely strong scientific underpinnings… or to put it another way, I know almost nothing about actual engines but could build an ICE from first principles if sent back in time 🤪😉 The actual fault being thrown is DPF showing as needing regeneration but not actually regenerating (even when manually set to do so via VCDS and run at the stated 2000+ RPM cruising at 70ish for upwards of an hour), then within another hundred miles hitting workshop fault and limp mode. Tricking it clear via VCDS gets about 500-600 miles of running no issues then exactly the same - except for the last time after an oil and filters change when it went 1200 odd miles prior to the same sequence. The vehicle is my daily drive but owned by my dad - hence why he gets the call on work like this; I’d absolutely not have tried deleting the DPF ages ago if it was mine as that would be naughty 😅🫣 thanks for the advice and part list already provided and in advance for any future suggestions etc! 🥰👍🤗

Hi all - as per subject, does anyone know the correct part numbers for the oxygen sensors on the CAYC engine, or where to find them out from?

I’d say if it ain’t broke don’t try and fix it tbh!! it will tell you if it’s unhappy. THEN come back with fault codes (your current doohickey/app pairing ought to read ‘em fine) and full engine data and somebody who knows what they’re talking about will likely (hopefully??) respond reasonably quick-like 😉🤗 It’s a piece of cake to reset (using VCDS & vag-com ODB/USB cable here as my brother happened to have one. Swore it was proper like. It’s definitely not kosher 😂 works tho 🤔🫡) but - given that it realises within 500 miles I’ve lied to it when I reset mine to clear the limp mode + 3 dash lights - I’d expect it to carry on happily until/unless it actually clogs…. I’ve seen posts from peeps running original DPF at 200k and more unless my memory fails me so not counting any ‘usage since new’ figures but pinging off actual readings AFAIK! And unless you have the relevant numbers from the previous vehicle, you’ll only be able to reset to zeros as if a brand new unit which will be even further off than pretending you changed nothing and carrying on regardless 😂🫡 ——- Hi btw 🫣 new here but not new on t’interwebs (if you never dialed in to a bbs for “vital driver updates” that took hours for a couple megs… um, be happy i guess? T’was utterly crepe!) And I know NOTHING ABOUT CARS!! ..in general. If I’ve owned it I’ll have taken apart and put back together most accessible subsystems (I am the poster child for ADHD on far too many of the days 🤦‍♀️😂😎) and rabbit-hole-researched it to death. Okthxbye 🫡

Just got my first Skoda a few months ago after my RX8 sadly died (and stranded me 100 miles from home- on Christmas 🤦‍♀️) - 2017 superb with 198k on it. i didn’t bat an eyelid as before the RX I’ve pretty much always run Peugeots with diesel lumps… therefore I consider an oil and filter change a full service, but do it every 6k religiously, routinely had 250 to 300k no hassle, got one to just under the half million mark. And then the steering rack went engine still kosher 😂 I’m very glad to see that I can expect similar with this beast!! Poor thing desperately needs a full drain and fresh fill of oil… dipped it once and the end of the stick was covered in pure evil 🫣😳 I’m shouldn’t say what I paid for it. As you’ll hate me😂 pure serendipity my brother had a colleague who’d pranged this slightly and then not sorted it or touched it in months… and his lady had enough of it sat there so he needed it gone… got it for a monkey and a case of cheap red wine. Put a day or two labour and about £700 in parts into it and it’s golden. Never had a bargain like it in my life!
