SL/R230: ABC Malfunction
The ABC Malfunction comes on and stays on until I restart the car. Usually comes on after a quick turn
Thanks
Every time I got the error I have turned the key fast. If I wait ½ a second in the second key position before start it up I never get the error.
Have You try driving the car in ABC error mode? I have and I can tell You its no fun ride. The car bounces all over. It’s virtually un-driveable without the ABC system.
I have the car in at the dealer once when the ABC error didn’t came off even after a couple of re-boots and they didn’t find anything wrong with it. All they did was reset the error code and all was normal again.

ABC Red Error came up... Tried to do the restart to fix it, but no luck... Took it to the dealer and they didn't find anything wrong with it.
When my error was on, it floated like a Caddy.... Super loose suspension.

So sorry to here this funtion is not operating correctly. Yes, my 2007 SL 550 did the same thing but I turned it off within a few minutes and turned it back on.....the malfunction cleared.
Still got my issue with the passenger side window not pointing toward the curb when in reverse though.....

No ABC issues on my end yet. Someone had mentioned that they turn their ignition key immediately without pausing, causing the malfunction light to come on.
I always use the button on the shifter and haven't noticed anything awkward.
I will keep an eye on this and fill you in if things do change.

1. REPLACE ABC FRONT VALVE BLOCK AND CORRECT FLUID LEVEL
2. A.B.C. LIGHT INTERMMITTANTLY COMES ON AFTER SITTING
NECESSARY TO RELEASE PRESSURE ON SCREWS, REMOVE COVER DISCONNECT HIGH PRESSURE AND RETURN LINES IN ORDRE TO
REPLACE VALVE BODY AND BLEED SYSTEM AND FLUSH SYSTEM AND PERFORM ADAPTATION
3. Replace ABC pump ($3000.00) If under warranty you should be good.

There are the three possible reasons for the issue. Good luck.
his car was under starmark warranty and they just could not fix the problem.
Hence, he's driving a brand new G35C fully loaded with no bs crap.
I hope MBUSA is listening. The quality of MB is no where near it used to be. My dads e320 runs like a champion. So does my e430 4matic.
come on ya, fix the damn problem.
I took it in the dealer and they said the suspension hydraulic pump is going to be replaced ( I assume thats the ABC pump).
MBUSA is useless. They used to be very responsive to their customers. Cars have issues but competent dealer and caring manufacturer responses can take a lot of sting out the problems. That doesn't happen with Mercedes anymore. I'm on my fourth and last SL. When the E430 needs replacement, no more Mercedes.
I'll either go back to BMW or even try an Audi. None inspire any great confidence, but non-German cars seem so dull to drive by comparison. I guess it's the lesser of the evils but definitely no more Mercedes Benz and I do tell anyone who will listen to avoid them.
I knew my SL600 would have lots of problems when before I bought it so I got the extended warranty to the max...For your SL500, you have one less thing to worry about and that is the engine. I heard that a repair relating to the V12 would cost an arm and take forever...
Nevertheless, the ABC problems are inherent for all these cars. Same goes to my E55, the airmatic struts died on me around 39k miles but luckily its all replaced under warranty.

ABC system dips car after 1 hour; take to dealer and they replace valves.
ABC dips again next day; take to dealer and they replace pump.
ABC dips again, dealer replaces fluid.
ABD dips again, dealer replaces struts.
ABC dips again, WTF, what's next?

Dealer is perplexed; we have had a replacement car now for three weeks off and on.
I think the dealer/manufacturer will be buying back this car and branding the title as a POS. Fortunately, it is under warranty.
Anyone with similar issues for a 2006 SL500?
The warranty ran out this past March, but not before I brought it to another dealer (since I met a tech who works there) who did about $9k in warranty work for me - inlcuding 3 out of 4 new struts.
I guess decent dealers are still out there, but a lot of them are ust getting really lazy.
