Thalia Engine Power Loss

Sounds familiar. I had a similar experience with my Thalia. Reduced power is a pain. Did you check the main relay? That was my culprit.

Could you elaborate on the specifics of the relay's failure and its consequential impact on the engine control unit's operational capacity?

Sure, relay was faulty, causing intermittent power to the ECU. Honestly, just take it to a workshop. They can diagnose and replace it quickly. Probably isn't worth the headache to fix yourself.

I appreciate your guidance. It appears your assessment aligns with my initial suspicions. I'll take it to a qualified technician for a comprehensive diagnostic evaluation. The estimated repair cost is 120€.
