Renault Master electric battery issue

I encountered something similar with my Renault Master. The symptoms you describe – discharged battery, error messages, flickering lights – strongly suggest a problem within the electrical system. Have you checked the battery sensor? A defective sensor can lead to such issues.

Thanks for the quick reply. I haven't checked the sensor yet. Could a faulty battery sensor really cause all these symptoms, or is there anything else I should look at?

Indeed, a defective battery sensor is a plausible cause. It can disrupt the charging process, leading to a discharged battery and subsequent errors. However, without proper diagnostic equipment, further investigation may prove difficult. Given the complexity, I suggest consulting a qualified workshop to perform a comprehensive assessment. I had to do the same.

Okay, I appreciate the advice. I'll take it to a workshop to get it checked out. Turns out it was indeed the battery sensor - cost me 315€ to replace. Thanks again for pointing me in the right direction!
