    Suspension Problems - SLS

    My 2000 SLS (105K), has had the service suspension warning on since I bought it several months ago, but it had some more pressing issues (alternator, brakes, radiator). I know it needs shocks (particularly in the rear).

    Having said that, it started a new problem this week. The ride suddenly gets very stiff. So much so, it feels like you are driving a farm truck. At certain speeds, you would swear the wheels were not round. It does have new tires and brakes.

    I wonder if putting it on the lift knocked something out of line. And, I was convinced the load leveling had gone crazy and over-inflated, but from what I read, that is not the case.

    Is there a fuse or something I can do to disable the electronic shock controls until I get time to put shocks on the car?

    Any other ideas for a quick fix? This problem seems to be very random in how it comes and goes, but it is very uncomfortable, and perhaps unsafe.

    Look at RPO code sticker on spare tire cover. What are the F options? Like FE1 or similar?

    Run your VIN through an rpo decoder online

    I cant find what you are describing, do you have a link?

    ----------

    I called a dealer and they said it was too old.

    ----------

    It is a base SLS, not many extras

    It's not too old, they're just being lazy.

    Google free VIN decoder.

    You can get it at www.compnine.com for $5.

    EDIT:
    Disregard. Apparently there ARE a lot of free ones.

    Ah, CVRSS is F45.

    Have you pulled your codes yet?

    See the sticky at the top of the Eldorado/Seville page if you don't know how.

    The ones that seem relevant are IRC U1016 history, RIM U1255 history and RSS C0620 Current, also all history, Abs c1246 ddm b1982 vtd b1009 and vtd 2934

    They're meaningless without their definitions.

    After another look, only the rss C0620 seems relevant, front right position sensor

    Thanks to those that helped. The issue was unexpected and outside of technological tracing.

    I isolated the issue to right rear so I pulled the wheel. It was caked in carbon. I presume brake dust, but I don't know how it got so hard.

    Tapping with a hammer, I knocked off pieces the size of the end of your pinky.

    I wasn't sure I had accomplished anything, but when I put the wheel back on, the hub was two inches lower. I had to raise the car higher to put the wheel back.

    The carbon/dried gunk was prohibiting travel of the shock.

    I took it for a drive and comfort had been restored.

    I wonder what a mechanic/dealer would have charged?

    Seems the shocks aren't as worn as I thought.
