Air Suspension - Deflating

[penet05]

My vehicle only deflates (in a few minutes), when it is parked incline/decline. Do you think it is the air bag leak, or something with the sensor?

Thank you for responses.

Air bag leak is pretty common on these vehicles at around 5 years of age, guessing yours is a 2014-15?

Apparently it’s a fairly simple DIY, ours (both sides) were replaced by the dealer under CPO warranty

Better to get it fixed ASAP before you wear out the compressor

Hi I think I have a same problem, this morning when I was driving I notice the suspension was very bouncy, so I stopped the car and shifted to sports the suspension went down and I shifted to comfortable there was a lot of deflate noise, however I still feel that the drive is very bouncy. I parked and waited for 2 minutes then I noticed the car is almost touching the wheels. Can you please give an indication how much will it cost me, mine is out of warranty?

Hi, Sorry if I post this in the wrong place. This is my first post.

I had the same problem with one side in the rear deflating. I got it fixed2 weeks ago. It was a leaking airbag and cost £200 altogether by my local garage
Thanks

Lol never understand why it's so hard for people to search. They do it every day on google.

Thank you for responses.

Try putting a couple of Viagra in the tank with the next fill-up. If that doesn't work, try a search.

I think you did not understand the question in detail. I know that the airbag can be the likely symptom, but since it only happens when the car is inclined/declined made me think that it might be the leveling sensor. I don't find a post providing the same symptom with this scenario.

Hi just an update, I found out it was the rear air bag which was leaking, thankfully I got the knowledge from this forum, which guided me to find the exact fault, got the air spring for £195 + labour, hopefully I won’t have any problems.

It's not the sensor. It's your airbag.
