Hi All

Fairly new to my 2013 Panamera Turbo and working through a few issues - no warranty of course. The Chassis Failure light has come on now three times, its intermittent and does clear itself given time. What I have noticed the last two times it has come one, was once as soon as I opened the drivers door after a couple days of not driving it - and I heard a air hissing sound from the front of the car. Next time, same hissing sound as I opened the back hatch after a few days of it sitting again. Each time if I started it up after this sound, the Chassis Failure message was there.

Its with my mechanic now, and they pulled codes and said the compressor/pump was bad and needs replaced - parts and labor about 1800.00. My question is has anyone else heard this air hissing sound, I see threads about the air suspension but couldn't find my exact symptoms. And is the compressor the right choice by the mechanic or does anyone think it sound like something else is bad? Hoping he is just not picking the best option and wait to see if it fixed the problem.

Thank so much!

 

is one side or the other sitting a bit low after sitting for a few days?

hissing air to me would indicate a leak, not a bad pump, not that the pump couldn't be bad as well.

 

I have not noticed the car not being level, but I am going to watching for that for sure. Sometimes I think the mechanics just make a calculated best guess on the part to replace depending on what codes they pull, he even said it could be something else but this is what it first points to. But the compressor isn't cheap - so I don't like best guesses

 

yeah, sadly the codes aren't as precise as you'd like, problem code be further up/down stream with something that doesn't produce any codes......

the problem that caused the lights to some on in the first place could be enough to eventually kill the pump as well, you might be to the point where it isn't just one thing....

 

Intermittent failure may be due to a loose connection on one of the air shocks. The connector gets brittle over time. I had the pump replaced on mine since that is what they had diagnosed was the problem. Was not it, at all, wasted $2500 getting the replacement done and ended up being a $7 connector.

 

That's my same exact worry - that it will be something else. They replaced the compressor two days ago, so time will tell.
