Can a bad battery really affect the air suspension on a Bentley?
I'm hoping someone here can help me understand what's going on with my 2018 Flying Spur because I'm genuinely confused. Over the past couple of weeks, I've noticed that the air suspension seems to be acting up, sometimes the car sits lower on one side when I come back to it after parking, and occasionally I get a "suspension fault" warning on the dash that disappears after a few seconds. I took it to a suspension specialist who checked the system and said everything looked fine mechanically, no leaks in the air struts and the compressor was working normally. He mentioned that he's seen this kind of behavior before on Bentleys when the battery is starting to fail, because the suspension control module needs stable voltage to operate properly and low voltage can cause it to throw random errors. I honestly never would have made that connection on my own, but it kind of makes sense because I've also noticed the car taking a bit longer to start in the mornings and the start-stop system has been inconsistent. The battery in my car is original from 2018 so it's definitely getting old. I've been doing some research online and came across a really helpful page at batteryzoneuae.com/bentley-battery-replacement/ that explains the symptoms of a failing battery in Bentleys and why it affects so many different systems. I'm planning to get it replaced this week because if a new battery fixes the suspension issues as well, that would be a huge relief and save me from a much more expensive repair. Has anyone else experienced suspension weirdness on their Bentley that turned out to be battery related?
