Problem with the Self-Diagnostic Light in the Seat Ateca

Good afternoon, I'm having a problem with my 2019 Seat Ateca (Excellence TDI, Diesel) with 110,000 km. The check engine light comes on constantly, approximately every 1,000 km. At the official Seat workshop, they informed me that the problem is with the particulate filter, which clogs easily, but they did not recommend replacing it, as the filter is in good condition. They clean the particulate filter at each visit and explained that the vehicle does not perform regeneration, suggesting that before turning off the engine, the revolutions should not be above 1,000. Even following this recommendation, the engine light comes back on. What could be the cause of this problem and how can I solve it? Thank you.

A 2019 Seat Ateca is experiencing a recurring check engine light issue, attributed to a clogged particulate filter. The official workshop identified that the vehicle does not perform proper regeneration, despite the filter being in good condition. Suggested solutions include ensuring regular highway driving to facilitate DPF regeneration and checking for exhaust leaks or sensor issues if the problem persists.

Start by checking if your driving habits allow for proper regeneration of the diesel particulate filter (DPF). Ensure you regularly drive at highway speeds for at least 20-30 minutes, as this helps the DPF regenerate. If the issue persists, it might be worth checking for any exhaust leaks or issues with the sensors related to the DPF system. Let me know how it goes or if you have any further questions.
