Serena Air Suspension Fault

Ah, the joys of air suspension! I had something similar happen with my Serena, although it's a slightly newer model. Leaning, error messages, the whole shebang. Does it sound like there's air escaping from anywhere near the suspension? That was my first clue.

Thanks for the quick reply! I haven't really listened for any hissing sounds, I'll give that a try tomorrow. Where exactly should I be listening? And if it is the valve, is it a big job to fix?

Okay, so listen closely near each of the air springs, especially around the valve where the air line connects. A hissing sound is a dead giveaway. Regarding the 'big job' question, well, let's just say it's not a simple nut-and-bolt affair. In my case, it definitely pointed to a defective suspension air bag valve. Given the symptoms you're describing, and to be on the safe side, I'd recommend taking it to a reputable workshop with experience in pneumatic suspension systems. You might be looking at around 590€ for a repair, but it's better than causing further damage.

Thanks a lot for the advice! I checked for hissing and I could hear some from the left side bellows valve. Sounds like it is pretty much what you said. I'll book it into a workshop as you suggested. Cheers!
