Seat Leon 2010 Diesel: Symptoms and solutions for black smoke, engine problems and high fuel consumption

Hi everyone, I have a problem with my Seat Leon, built in 2010, diesel, and already 189415 km on the clock. It emits black smoke when accelerating, the engine light comes on and sometimes the engine just stops. The engine also runs unevenly, there is jerking when accelerating, the fuel consumption is high and it smells strongly of exhaust fumes. And sometimes it even stalls when idling. I had a bad experience at the mechanic and am now on pins and needles. I suspect that this is all related to the rail pressure sensor. Have any of you ever had similar problems and can perhaps give me some tips on what I should do now? Thanks in advance.

Hey, I had the same problem with my 2013 Seat Ibiza, it was the turbocharger that was faulty and causing all the smoke and smell. I also had a bumpy engine and sometimes my car just gave up the ghost. At first I thought it was the rail pressure sensor, but it wasn't. I was lucky that the mechanic at my garage is really on his toes. Definitely not such a small problem, so you'd better get it checked quickly at a trustworthy garage. Hopefully it's not as serious for you, but better get it looked at by a professional. Good luck with that, hopefully it's nothing serious on your end.

Hey, thanks for your contribution! That sounds really bad with the turbocharger... I can't even imagine. Do you remember what you had to pay for the repair? And has everything gone smoothly since then, or have there been any other surprises? Hopefully it really is "just" the rail pressure sensor in my case... Anyway, thanks for the advice to have it checked by a professional.

Hey, you're welcome! Yeah, the turbocharger thing was a real shock, but let's face it, car problems are never really pleasant. If I remember correctly, I had to fork out about €640 to fix the broken fuel pump. Since then, however, it's been running like clockwork - the rail pressure sensor problem, which was also under discussion, was fixed at the same time. So no more nasty surprises so far, fortunately! I can only advise you to have it checked by a professional. The sooner you tackle it, the better. Good luck with that, hopefully you won't have the same problem with your Seat Leon.

Holy moly, 640 €?! That's really quite a lot. I sincerely hope I can get away with less. Good to hear your car has been running smoothly since then and no more surprises. Your advice was really valuable and I will definitely get this checked out by a professional now! Thanks again for your time and advice. I'll report back when I know more. Keep your fingers crossed that I don't have the same problem as you. See you then!
