Hey guys with the 301, I'm feeling that the car noise is too loud. I just did maintenance two months ago and also replaced the tires with the original Giti 221. What's going on? The engine hood and trunk lid don't have any soundproof cotton. Would adding some help? Have any of you guys tried it?

It sounds like you're experiencing an issue with your 2012 Peugeot 308 not starting, and you're hearing a clicking sound with the onboard computer resetting. Since the battery has been tested and has power, the problem could be related to the starter motor or its connections, the ignition switch, or a potential issue with the car's electrical system, such as a bad ground or corroded terminals. It's recommended to have a professional mechanic check these components to diagnose the exact issue.

Has any owner of the 3-motor version of the XP noticed a 4% drop in battery health after six months? I personally feel that I've taken good care of the battery, usually charging between 50% to 80% (slow charging), rarely using fast charging, and charging to 100% no more than five times. When not in use, I keep it plugged in and haven't driven aggressively or used the straight-line speed mode. Despite this, the battery health has still dropped by 4% in six months. Is anyone else experiencing the same thing?
