Latitude ECU Error Code

I'm having a weird issue with my 2012 Renault Latitude diesel. It's got about 40k km on it. Lately, the engine power has been noticeably reduced, and after running diagnostics, I'm getting an error code pointing towards the engine control unit. I've checked the basics, but I'm suspecting the main relay might be the culprit. Has anyone encountered something similar with their Latitude?

I recall experiencing comparable symptoms within my Renault Latitude. Was the diagnostic error memory populated with a recurrent specific code, or a multitude of sporadic faults? Furthermore, were there any concurrent anomalies with other vehicle systems?

Thanks for the reply! The error code seems pretty consistent, always pointing to the ECU. No other weirdness that I've noticed, just the power loss and the error code. Did you manage to fix it yourself, or did you end up taking it to a shop?

Given the consistency of the error and lack of other system faults, a workshop visit might be prudent. In my circumstance, a defective main relay induced similar ECU behavior. The replacement procedure necessitated specialized diagnostic apparatus. While I am proficient in mechanics, the intricacies of modern automotive electronics necessitate professional intervention to preclude further complications.

Appreciate the advice. I'll take it to a workshop and have them check the main relay and the ECU. It was indeed the main relay. Cost me 120€ to get it sorted. Thanks again for pointing me in the right direction!
