Airmatic problem

Erection malfunction in vehicle

Misfire?

gaspam

the first answer was the correct one, airmatic malfunction, all other answers were just joking

airmatic malfunction could be just a loose ground wire, a bad compressor, leak in one of the airbags, leak in the compressor, and few other reasons but those are the most common

Your car tells you when it's time for coffee??

Here is the answer I got from my SA manager:

You have an airmatic malfunction, possible leak in the air suspension system, strut, bags, compressor, pump. If issue is left ignored, suspension starts to lean to one side to the point the fenders will rub against the tires, control arms could rub.*

Thanks guys. Went to the dealer and he gave me the same reasons as "possible leak in the air suspension system, strut, bags, compressor, pump".

Sounds like a major fix and out of warranty!!!

Got an appointment early next week to take it in! Wish my pocket good luck!

your car does too... its called "Attention assist" and you can turn it on or off via steering wheel/dash inputs

it basically notices when you start to do repetitive minor swerving on long drives and interprets that as you are tired (or drunk lol) and tells you to pull over and get coffee

well luckily the w212 e63's only have air suspension in the rear so shouldnt be too bad... on the e55's they had it in all 4 corners and the front suspension was much more expensive than the rear.

when i had my e55 i replaced mine myself when they failed and MB wanted $2500 per corner but i was able to get the parts for about $390 per corner from Arnott and do it myself

if it does end up being the rear air spring, you can get them from Arnott for $250 per corner https://www.arnottindustries.com/par...4_gid1219.html

I want coffee, gf doesn't. Gentle left right left right... HEY BABE! The car says we need coffee.

Brilliant!

When was your car built? It wasn't in mid 2011, was it?

There was that air bellow problem but newer air bellow parts starting with late 2011 built date seemed to have resolved the problem.

Hello. Front airmatics sagging. Rear airmatics respond to OBD normally. Front don't fill with compressor filling. I've had spotty airmatic warnings by instrument cluster, car-and-up-arrow warning occasionally and vehicle ride has been fine. From the info provided, does this appear to be a shock failure issue only or have I more digging to do?

Thank you.

Excellent survey job: clear status.


-- Your fronts bags are not filling....

-- Compressor does run.

-- Level sensors are working well.


> I would focus on your valves being internally rusted before suspecting bags that normally do not fail together.

Thank you. I'll begin at central reservoir charge valve.

New valve block installed. Left inflated, right remains low. OBD old data:



new data:


New sensor OTW.

Great job!
Now let's use soapy water in a spray bottle to look for air leaks at hose connections and at air bag itself.

Your sensor data looks accurately reporting.

I bet the initial air leak caused the compressor to pump up enough air volume to build up water condensate that oxidized unprotected valve inards.

Are you located where water freezes in winter below 0°C?

If so research a way to drain water condensate from this amazin' system. Truckers have this issue of frozen air brakes and use some type of antifreeze alcohol.

"Now let's use soapy water in a spray bottle to look for air leaks at hose connections and at air bag itself."

Done. Audible leaking from inside the bellows though the soapy water showed no clear evidence of outflow.

Yes. It is often below zero here.

New shock otw.

Thank you for your input. I use it all.

.... in this case shocks take an "S" for a pair

You do not want weird front end behaviors or at least take it easy if L/R handling is uneven.

Your excellent labor discount is paying for all your repair parts.
