Skoda Fabia diesel engine problem

Good day, I am writing to report a problem I am experiencing with my 2002 Skoda Fabia's diesel engine. The mileage is currently 81605 km. A warning light has appeared on the speedometer, and the engine power is also reduced. I have also noticed smoke when accelerating, along with a very strong exhaust smell. After some research, I suspect the issue might be related to the diesel particulate filter, with a possible "exhaust back pressure too low" error. Could this be caused by a defective pressure sensor?

Oh dear, that sounds familiar! I drive a Skoda Fabia too, and I had similar issues with my diesel engine a while back. Reduced power and smoke... very annoying. I think it might be linked to your DPF issues. The DPF is the Diesel Particulate Filter, which reduces soot emission.

Thanks for your reply! What exactly did you do to fix the DPF issues? Also, what do you mean by 'exhaust back pressure sensor'? I am a novice with these new emission control thingies...

Well, in my case it was the exhaust back pressure sensor indeed. It seems like it is a common problem for diesel engines. The sensor measures the pressure in the exhaust system. If it fails, it can cause all sorts of DPF issues, triggering that low pressure warning and affecting emission control. I'd suggest taking it to a workshop to confirm. They will be able to diagnose the sensor or other potential problems!

Thank you for the help! I took the car to a workshop, and they confirmed it was the exhaust back pressure sensor. The entire repair cost 245€. Hopefully this fixes the problem with my Skoda Fabia's diesel engine.
