I’ve been searching for an answer to this question without much luck. I have a 2014 model s with smart air suspension that is now having some repeating issues with the car getting “slammed” or lowered related to the air compressor and air shocks. Instead of sinking more money in to fixing these air suspension issues (and I’m sure there will be more) is it possible to just revert to coils/springs? Is that possible? Seems like it would just be way more reliable.

Funny, I would trade my S with coils for one with air suspension without any hesitation.

The airsuspension isn't that complicated, best thing to do is take it to a proper shop that are able to help you or give us a more detailed description of all the issues you have with the airsuspension.

That's funny. I would trade my S with coils for one with half-air suspension and half-coils. I like the firmness of coils but need the comfort of air only in certain conditions. I wouldn't split them front and back though. I'd arrange them diagonally with air suspension only on the front passenger side and the driver rear side. This is where my wife and mother-in-law sit respectively and apparently where all of the bumps in the road are.

Here are a few more details about the issues I’m having I just posted to another thread. Basically the air suspension has failed twice in 6 weeks. Was repaired the first time with new solenoid and air compressor but failed the same way 6 weeks later. I’m stranded without being able to get in to my driveway the car is so low. Anyways here are the details I posted in the other thread:

2013 model S 60 with tech pkg and air suspension.

I recently had the 12v battery service performed by a mobile tech, on the same visit they replaced the washer fluid nozzles and a tpms sensor. After the service was performed it was a few days later that the air suspension started warning us about a problem and it sounded like the air compressor was running non stop. I immediately noticed a small puddle of dark brown oil/fluid where the car was parked in the garage near the front driver wheel midway. Anyway It rides like crap and is only a few inches off the ground with the tops of the tires tucked way up under the fender, it is sitting at the lowest possible setting and scrapes the driveway and bottoms out hard even at creep so basically it is not drivable. I called Tesla and they said they would get service to call for an appointment but it’s been over a week since. I opened the frunk and removed the tub and liners to get a view of everything and saw no trace of oil or fluid anywhere. I checked under the strut cover area also and found the same. So anyway I am unable to use the car and don’t know how to proceed with diagnosis. I read the fixed air hose for a dollar thread but not sure how to find that leak if that’s what it is. If anyone could offer some help it would be much appreciated.
This exact same thing has happened to me, however I didn’t notice any liquid under the car like you did. Mine also happened after a tech came out to replace the 12 volt battery. The car was slammed at the lowest position and the pump ran constantly until it failed. I took it in to the service center for repairs and they replaced a solenoid and air compressor for ~$1200. Now one month later the exact same thing has happened again. This time I removed the tub to pull the plug on the air compressor so it doesn’t continue running and burn out. I’ve used a tire gauge to measure the psi of air in the compressor holding tank and can’t detect or hear any leak. I hope I don’t have to keep paying ~$1200 a month to have the air system fixed repeatedly. One additional interesting thing is that on both occasions that this happened there was a significant vibration that shook the steering wheel and then the you could hear the pump (or maybe another pump) rev up loudly. It’s crazy how similar the 2 cases I’ve had are. I did have about 6 weeks of no issue driving in between though.

Anyways, can you share what was done to resolve you issue since it sounds like it may be similar to mine?
Also, anyone else experience this? Currently I have to wait 3 weeks until my service center appointment and my car is pretty much un drivable as is. May have to take it to a regular suspension shop. Thanks for any feedback anyone may have. Really bummed…

take it back - such a repair $1200 - it isn't fixed and you already paid.
perhaps something else broke? hole in air bag?
or are you just a troll making s* up?
