Has anyone refreshed their Smart Air Suspension (SAS)?

[maximizese]

Our 2013 S85 is in the Service Center for a number of issues:

rear seat belt tensioners locking and not releasing
two tires mounted on backwards
intermittent TPMS readings
"Car needs service: Car may not restart"
"Acceleration and top speed reduced"
"Regenerative braking system disabled"

I picked up a 2019 S75D loaner with just 17K miles on it and I'm afraid I'm in love. Next-gen textile seats, sub-zero package, UHFS, unrestricted SuC speeds, ambient lighting, hi-res display/MCU2/LTE, Netflix/Hulu/Youtube/Twitch streaming, and a young SAS air suspension system. The car feels much more solid, cushioned, with much reduced body roll. I'm not sure if the SAS has been greatly revised and improved between 2013 and 2019 or if mine is just worn out. Our suspension feels less dampened and much more float sensation with body roll. I started looking into replacement components and stumbled on what appears to be a bargain-basement option from Suncore:

Suncore Industries - Front & Rear Suspension OEM Remanufactured Air Struts - 2012-2015 Tesla Model S

Has anyone given these a shot? These reman are much less than the parts counter at Tesla and $862.50 is a bargain for any car. I'd bite if these would give me the same tight and dampened ride that this loaner is offering.

I wonder if your loaner has the new Raven active suspension.

I agree completely with everything you said about the 2019 75D. We had a loaner for a month and absolutely loved it.

I bet your loaner has Raven suspension. I’d verify that before investing in new parts.

 

[PWlakewood]

Check the month of build to see if if has raven suspension also you can adjust the suspension from the menu if it's a raven build.

Good point to check the manufacture date. It's a 12/19 build and does not have adjustable dampening...but it rides so well. Much better than my 2013 S85. I guess I'll ask the service tech if my suspension is worn after 90K miles. It doesn't pitch and dive, but it does roll (yaw) significantly more than the S75D. Since the Suncore reman states "2012-2015" TMS, I wonder if Tesla made a some revisions and improvements to the suspension over the years and if they are interchangeable (at least with pre-Raven models).

Some MS' have thick anti-roll bars. This would make a big difference if you could find them salvaged.

12/19 build is 120% a raven suspension. It would feel more solid even against my 2018 100D in terms of cushion, body roll, handling.

if your trying to get your model to duplicate what you just felt, it may be impossible. I’d drive a non raven suspension first to judge if your suspension is worn.

What is the diameter of the sway bars on a raven car? I checked the front on my car and it's 27mm. I have not been able to find measurements on the various cars (standard, plus, raven) if they are different.

 

[rooter]

The 2015 P85D would be best to get it from. They've heavy. May be others I'm not aware of.

I'm sorry. Major typo. It's a 12/18 build. That makes a big difference in the Raven/not-Raven suspension, but it's still so much better than our 2013 SAS. I'll have to have a Tesla Tech give me their feedback on the condition of our car.

Ah ok. Then it’s a pre-Raven 120%. Lol.
Could be some shocks you need to replace after 7 yrs. The car is 4750lbs after all. Quite a load on the suspension long term.

 

[Raechris]

All Ravens are long range

What is unrestricted SuC speeds? What year MS have streaming and games?

I believe the "games" require MCU2, which is March 2018 and later.

Has anyone actually bought these and had them replaced. I recently ordered them thinking I could do it myself, but apparently I need to take it somewhere. Im pretty sure Tesla wont do it for me, and I called a couple local shops, and they don't do any work on air suspension. Not sure what to do?

Not sure where in IL you’re located but if you haven’t called Blood Type Racing in Glenview, they may be willing to help. They very ably installed my MPP sport coilovers on the 3. Small shop but very capable. Try ‘em. Good luck.

Thinking out of the box, there have been tremendous improvements in Model S since yours was produced, let alone the +90,000 miles.

The prices on Model S have come down a lot from when you bought yours, and tons of enhancements as well.

If you liked the new suspension, you will go bonkers over the new Raven package. You will get much more range and faster Supercharging from the new Long Range, 100X faster computer, better aerodynamics, improved seating etc..

Worth a look. Maybe better than putting a lot of $ into bringing your older S up to date.

Has anyone refreshed their Smart Air Suspension (SAS)?

Just pull the plug, drain all of the old air, find a tube and just blow as hard as you can with some new air, this will get you sorted

But if you're feeling frisky and want to go with the crazy adaptive suspension, you pay a guy with Corona to blow the tube for you
