Estima Diesel Injection Issue

That sounds familiar! I had a similar problem with my diesel Skoda Octavia. The engine was behaving erratically, and the check engine light kept popping up. It turned out to be a fuel injection issue. Have you noticed any changes in your Estima's fuel economy or performance lately? Monitoring fuel efficiency and airflow sensors gave me useful clues before it got critical.

Thanks! Yes, there's been a slight decline in fuel economy recently. How did you monitor the airflow sensors, and what data was most indicative of the problem? Are special tools needed?

I used an OBD-II scanner to read live data from the airflow sensors on the Skoda. I looked for anything outside the manufacturer's specified range. A large deviation in airflow readings or inconsistent values at idle were the first indicators. Even with that data, I'd suggest taking your Estima to a trusted workshop; the 'reset quantity drift compensation' error sounds like it requires specialized tools and expertise to diagnose and repair correctly. It sounds like an injection valve or injector issue, like you mentioned.

I appreciate your detailed explanation. I've scheduled an appointment with a reputable workshop to inspect and address the potential fuel injection issues. The estimated repair cost, including parts and labor, is approximately 515€.
