Seat Leon FR estate car starts badly
(Translated from German)
Summary of the thread
A 2012 Seat Leon Diesel is experiencing several issues, including a constantly illuminated engine light, stalling, extended cold start times, reduced engine power, uneven running, jerking during acceleration, and occasional failure to start. The suspected cause is a malfunctioning fuel pump. A suggested solution is to have the software values of the fuel pump checked and updated, as a similar issue was resolved with a software update in another vehicle. If the software update doesn't resolve the problem, the fuel pump itself might need replacement. Additionally, reading the fault memory could provide further insights into the issue.

Hey, thanks for the quick reply! That's good news and I'm glad to hear that a simple software update solved your problem. Mine already has a whopping 176432 km on the odometer and the last service was about 6 months ago. I'm not sure if the model is important, but luckily I have the data: It's a Seat Leon 5F. I think I'll follow your advice and go to my garage. Thanks again for the tip!

No problem, always happy to help! With your Seat Leon 5F, it could definitely be the software, especially with the high mileage and the last service 6 months ago. Don't worry, the guys at the garage will certainly be able to help you. Have them check the software values of the fuel pump and update it if necessary. If the software update doesn't solve the problem, there's still the possibility that the fuel pump itself is faulty. Then you would need a new pump, which would of course be more expensive. But let's not assume the worst! And don't forget to have the fault memory read out. This can often give you further clues to the problem. Then tell us what you find out. Good luck!

Great, thanks for the detailed advice! I will go to my garage and have the software checked. And of course I'll also have the fault memory read out, I'd totally forgotten about that. You're right, it could also be the fuel pump itself - let's hope for the best. I'll definitely keep you posted on what comes out. Thanks again for your help!

Hey, I had a similar problem with my 2010 Seat Ibiza. I consider myself an occasional mechanic, but I do a lot of my own work on my car and I'm learning every day. So I have some experience. To solve the problem, I went to my garage and the guys checked the software values of the fuel pump. It turned out that the values were wrong. They did the software update and that was it - everything is running like clockwork again! It cost me around 45 euros, which was actually pretty fair. Hope that helps you. Can you perhaps tell me the exact model number and other details about your Seat Leon? Then I could give you more specific support.
