Exhaust back pressure sensor error in a 2001 Opel Omega: experience and tips wanted

Hello, I had a similar problem with my 2004 Opel Astra. The DPF was also heavily overloaded. Yes, I would say it was a serious problem as it severely affected the driveability and especially the performance. In my case, they first tried to clean the DPF, which is a standard procedure when the DPF is clogged. However, when this didn't work, it turned out that the exhaust back pressure sensor was faulty and needed to be replaced. One thing you should make sure you do is ask your mechanic to show you exactly what is faulty before he replaces anything. This will give you a better understanding of what's wrong and whether the suggested steps make sense. In my case, it really helped me to understand things better and to have confidence in the whole procedure. As stupid as the situation is, cheer up! It's a known problem and after a correction, your car should run as normal again. Good luck with that!

Hi, thank you for the tips. Sounds like a bad experience you had with your Astra. I'll ask the mechanic if he can explain and show me the problems before he replaces anything. Unfortunately, I've often had the feeling that I was being ripped off. Can you remember how much you paid for the repairs? And have there been any further problems since then or was the problem solved? Thanks again for your help and your words of encouragement. I hope this really marks the end of my suffering with this car. Regards.

Moin, yes, this experience really wasn't the best, but I'm glad it's fixed now. After the mechanic replaced the exhaust back pressure sensor, the problems were gone. As for the cost, it was a bit more expensive. To be precise, it was €1325 to fix the DPF. That may sound a lot at first, but my car has been running like a dream ever since. So it seems like money well spent. I really hope that you have peace of mind afterwards. I'll keep my fingers crossed for you and I'm sure it will work! Best regards.

Hey, thanks for your quick reply and the helpful information. 1325 is indeed quite a hefty sum, but if it solves the problems and the car runs perfectly again afterwards, then it's probably worth it. I'm also really hoping that I'll finally have peace of mind with this issue. I'll see how the whole thing develops and whether my mechanic can classify the problem in the same way. Thanks again for your advice and support - it really means a lot to me! All the best and hopefully your car will continue to run so reliably! Kind regards.
