Complications with Skoda Octavia: suspected defect in the exhaust gas temperature sensor

DPF regeneration failure

Check engine light on

Loss of engine power

Hello friends, Recently my Skoda Octavia Diesel (2019, 28300 km) has been really strange. The indicator light is on, the engine power is down and the DPF regeneration won't work. I suspect that the exhaust gas temperature sensor is faulty. Have any of you ever had similar symptoms in your car? What did you have done and how did it go at your garage? I had a really stressful time with my mechanic last time... I'm grateful for any tips!

Hi, Had a similar problem with my Skoda Superb diesel (2016, about 230,000 km). There was also an indicator light and a decreasing performance feeling. During my last inspection at the garage, it was then found that the DPF (diesel particulate filter) was clogged. It was something serious as this could lead to major engine damage. Don't worry, your suspicion about the exhaust gas temperature sensor could also be correct. In both cases, however, I would advise taking the car to the garage as soon as possible. Hopefully you'll have better luck with your mechanic this time. All the best!

Hey, thanks for your answer. You seem to have a clue! Now, of course, I hope it's not the diesel particulate filter in my case too. But what must be done, must be done... Can you still remember how much you had to pay for it back then? And have you had similar problems again since then, or was there really peace and quiet? Best regards!

Hello, no problem, always happy to help! Yes, I can reassure you, everything has been fine since the workshop visit and I haven't had any more problems. The defect in the exhaust gas temperature sensor was repaired - everything has been quiet since then. As for the price, I can tell you that I had to pay €52 to repair the defective fuse and the power supply. So don't worry too much, it'll be fine! All the best!

Hi, great news that everything is back to normal after your workshop visit. The price seems quite fair too, I can adjust to that. I'll take my car to the garage tomorrow and hopefully they'll sort it out quickly. Thanks again for your support and advice! Best regards!

Hi! That sounds stressful. I haven't had the exact issue, but it could be the sensor. I would recommend getting a second opinion from another mechanic. Anyone else have experience with this? Good luck!

I agree with CarFreak. It's always a good idea to get a second opinion if you're not completely satisfied with your current mechanic's diagnosis. It could indeed be the sensor, but it could also be a clogged DPF as KlaraFahrer mentioned. Both issues are not to be taken lightly as they can lead to more serious problems if not addressed promptly.
