2010 Seat Leon Facelift 2.0 TDI - Persistent DTC P410-4 Troubleshooting Help

Model: 2010 Seat Leon Facelift 2.0 Fault Code: P4104 Posted: 2016-07-26 00:37

Hello everyone, First, sorry for my limited English (I'm French). I own a 2010 SEAT LEON FACELIFT 2.0 TDI (140 HP) — sharing the same engine as VW, SKODA, and AUDI models. My vehicle is showing a persistent DTC code: P4104 (Type: Permanent Trouble Code). After extensive research online, I'm unable to find reliable information about this specific fault code. Could anyone please provide insight or guidance on what P4104 means in the context of my SEAT LEON FACELIFT 2.0 TDI? Any technical explanation, diagnostic steps, or known fixes would be greatly appreciated. Thank you all for your time and support! Best regards, A French SEAT owner
