Dear Forum Members, I just thought I would update that the car has been fixed. The exhaust gas pipe had a broken seal and connector which had worked loose an additional joint. No wonder it was gasping with poor acceleration. Was a difficult job to get the new part snuggly fitted but job complete and the engine is back to it's usual sound. Thank you again. Best wishes, Malc

Dear Forum Members, After my previous Octavia was written off I thought I was fortunate to source a 2019 reg automatic, petrol version. I think I have been sold a duff car and I hoped your learned experience might help me troubleshoot the issues. I did not notice the sound when I briefly test drove the car but it has become more prevelant. When pressing the accelerator a hissing sound is produced, like a leaking aersol can or loosened pop bottle. There has been a decrease in the power output from the engine with the revs not rising steadily and aberant, sharp gear changes occuring. On Sunday the car struggled up the motorway incline sections quite noticeably. I know I need another visit to the garage but any advice on underlying causes would be gratefully received. I have changed the spark plugs quite recently. Some of the symptoms experienced yesterday were very similar to when a plug failed, although the car went into limp home mode which it did not do on Sunday. The car had seemed better but the hissing sound has become more obvious as time has gone on. I only do about 100 miles a week at most. The lightest touch on the accelerator pedal does not generate the sound but 95% of the pedal movement creates the noise. Releasing the pedal stops the noise immediately. I am very gentle with the pedal action, not a stomper. Best wishes, Malc

Dear All, I have collected my Octavia from the garage who have replaced the DPF differential pressure sensor. The documentation they provided included three error codes, as follows: 01 Engine Management: P245400 Diesel particulate filter differential pressure sensor circuit low U111300 Function limitation due to received malfunction value 09 Central electronics 01134 Alarm horn (H12) I haven't driven the car far enough to try the cruise control but the engine does sound a lot smoother and the knocking in 3rd gear has gone (warmer weather perhaps?). I am a little worried reading other forum post about needing to run an adaptation before starting to the engine. Is this well known and employed by garages? Hopefully almost a fully fit Skoda Octavia back in the line of duty. Any thoughts gratefully received. Malc

Thank you for continued support. The car is going to the garage on Monday and I will pass on your recommendations (TheClient). The cruise control isn't a major loss but its apparent failure alongside the fuel injector collapse is worrying to me. Hopefully the diagnostics can home in on the cause. I have not had my Octavia serviced at a VW/Skoda garage for many years. Possibly that lack of care has led to this situation. However the letter from Skoda clearly stated that no fix was required regarding diesel gate. I will check the VIN as you proposed. Have a good weekend. Malc

I can confirm that the brake lights are working perfectly and that there is no sticker so I am very sure no diselgate fix has been applied. I drove the car this morning and no error lights on the dashboard (glow plug). Seemed to drive okay, slight judder from the engine disappeared once the engine had warmed up. Cruise control still not working so I will go back to the garage and see if they can provide the fault read. If so i will try and post it here for anyone who is interested. Thank you again for taking the time to talk this through with me. Malc

T200: Yes they do but I will double check in case I am wrong. I would have expected a warning light for failed lights, but is that always the case?

"pikpilot": Thank you. I have to empty the bits from the boot so I will have a look and get back to you. "TheClient": Thank you for your kind offer. My family are very close to Guildford. If I can trust the car to get me down later in February I could let you know. Not sure I have the confidence to do the M1 run though - not sure about facing a breakdown in a live lane due to smart motorway restrictions. I would value any feedback to my following plan please: I am going to disconnect the new battery and turn on the lights to fully drain any electricity from the systems. I hope this might reset the electronics fully and might clear any gremlins. I will also pull and reset all the fuses at the same time. I did try and charge the battery so I wonder if there might have been some weird voltages in the system. If the Octavia is sensitive then this reset should purge the system. Thank you for your contiued thoughts and opinions. Malc

Thank you for your quick responses. "TheClient": There were no fault codes when the car was released from the garage. They suggested the cruise control might re-establish after a few good drives. It is just a fixed speed cruise control. I am not that technically capable, seeking to have the knowledge before my garage gives me choices. I have unfortunately spent over £2,000 in recent bills and I cannot afford any major work. "pikpilot": My apologies for the error. It could well be CR, I opted for GR as I believed the model was GreenLine. I was told by Skoda that no fix was possible on my model so no work has been carried out to rectify that issue. I did think that was a bit odd at the time. Thank you for all your suggestions.

Dear Forum Readers, Sadly I come to you seeking guidance as to why my Skoda Octavia SE TDI GR 1.6L (2010) is suddenly playing up and hoping that there may be a known fix so I don't have to get rid of a car that has served me so well over many years. Here is the story. About 3 years ago I was doing long daily driving commutes, nearly 2 hours each way. Irregularly the glow plug system light would appear on the dashboard but the car would never go into engine protection mode as the handbook and many forums suggested it would. Restarting the engine would often clear the light from the dashboard. My local garage could find no cause for this irregular error light, on two days in a week then a couple off then on again, etc. Changing my driving style (booting the car once in a while, or driving in a lower gear to help clear particles from the system) did not seem to have any effect on the warning light coming on. Having stopped the long commutes the light has rarely come on since. The car is barely driven to be honest maybe once a week with once a month long trips to help family. The battery had to be replaced, finally finished off by the cold weather. Then a slight judder from the engine block returning from Christmas, the glow plug system light came on again rapidly followed by the engine management light and the Octavia went into engine protection mode on the M40....not fun. The problem was a failed fuel injector #2, a known common fault. Repaired and serviced I hoped to rebuild my trust in a car that had never let me down until that part failed. However, the cruise control has not become active since the repair and the glow plug system light is back on, almost constantly only 50 miles having been driven since the repair. I haven't felt any juddering in the engine but last time that sign only came moments before the part failed. Has anyone sadly experienced events like this? Is the glow plug system light linked to further failing fuel injectors? Is my non working cruise control an omen of future engine failure leading to stranding on another busy motorway? Thank you for any advice, all appreciated. My apologies if this has been discussed elsewhere and I have failed to find the topic. Good health and safe travels to you all. Malc
