I did mine myself and 1 extra step before you remove the plug.. Get some kitchen roll and a long screwdriver or something pokey and clean around the plug / absorb all the extra plusgas before removing. There was a good bit of grime and I'm pretty sure you don't want that flying in once you remove the plug.

Open the bonnet, pull off the plastic engine cover, then watch the start of this: https://youtu.be/i2AEvaPXzn8?si=0J1heJ7Nn9op-Q71&t=80 Pressure sensing plug is the 3rd one over, it will have extra wires running to it

Mechanic said he'll only replace one due to the risk of doing 4 and 1 of them snapping

Hi tdog, I have the same fault code for glow plug cylinder 4. I'm only replacing the 1 plug. Can you remember if 4 was just a regular glow plug, or the more expensive pressure sensing plug? From what I've read online there are 3 regular and 1 pressure sensing.

No help here on how to remove but I had my alternator removed, reconditioned and refitted plus fan belt replaced for £160 total by my local independent mechanic. (listed as £90 materials and £70 labour on the invoice). So it might be worth getting it reconditioned if there's a place local to you?

Instructions state: "Remove the temperature or pressure sensor Insert the probe through the opening and Drain spray in the direction of the particulate filter." I'm searching on here, YouTube and Google and can't find any mention of temperature or pressure sensor in relation to DPF location? A guy in a YouTube tutorial shows him removing the O2 sensor and spraying the DPF cleaner in there? Car is a mk3 2.0 Octavia Scout if anyone has a location / description / picture with arrow they can point me towards lol.

Hey Geoff, Digging up this old thread, but just wondering what happened with the dpf as your oil ash was nearly full back when you posted this, and you seem to have kept the car for another while after? My oil ash is currently at 74.4, so trying to figure out what the future has in store 😂

Well did you find out what was wrong in the end? I'm in a similar situation.

OK I totally under estimated the mileage. 178k Also just bought the DPF app and it's showing 73.8g of ash and 92% full. Could this be causing the issues I've described?

2.0 TDI 150 hp Will update post Edit: seems I can't update the original post

Hi, I've have this Octavia for the last 6 or so years. Current mileage: 170k+ (might be 172 or 175 I can't remember lol) Have had the alternator refurbished and battery replaced in the last few years. Serviced every year with oil, oil filter, and fuel filter always changed. For the last year or so it's had random starting problems (a hard start every few weeks), it's always started but sometimes it will turn over a few too many times and seem like it won't start, and then it does. More recently it's happening now (like once a week, instead of every few weeks). On the most recent occurance it turned over maybe 10 plus times, then started and a small amount of smoke came from the exhaust. The dash also displays "start stop system unavailable" or "lane guidence unavailable". I read about dashcams causing battery problems and I installed one a few months ago, it's not hardwired, but stays constantly plugged into the USB port and only powers up when the car is switched on. I wondering if there's anything I can do / try / test before going to my mechanic. I've also attached a read out from car diagnostics that I had a friend just do. Thanks.

Hope you got the airbag sorted. For anyone reading, disconnect the negative terminal of your battery before removing the seats. And put the seats back / reconnect all wires etc before reconnecting the battery. This will save you from having to reset the airbag light. Also some airbag systems have capacitors which take a while to discharge, so I would disconnect the battery about 30min before removing the seats just to be sure. You can clean the dash / the boot etc in this time flif you're removing the seats for cleaning purposes.

Any guide or tips on how to remove the entire unit? I've got mine "opened up" where I can see the circuit board for the switch etc but would like to remove the entire unit and try to repair

Hey Stuart, All sorted now, had just bought the new matrix to fit myself (following the video of the guy fitting wrong first time lol) when the same pipe went again! Had to get recovered and brought to mechanic, so he fitted the new matrix, expansion tank and coolant pipe when they all arrived. The heat in the car is now warm within about 3-4 minutes of running vs when I bought the car I always thought it was slow to warm up the air. The silica bag has probably been leaking slowly for 3-4 years as this is a night and day improvement on heater warm up time.

Had my clutch replaced by an independent Skoda mechanic for £440 labour. I supplied all parts, including new cylinders etc. Replaced everything. Edit: 2015 manual Scout
