I own an sl55. I put up the roll bar while doing some track driving. Now i can't get it back down. Error message comes up to push the roll bar up. I have tries pressing the button in both directions and held for many seconds. Manual says take to Merc Garage. Is there a quicker way of getting it back down?
It should reset whet pressing the roll bar switch to the up position as you have tried - it can take a good 10 secs of pressing to wind the mechanism back up & re-engage.
Try once more keeping the switch pressed for longer.
If it still wont reset then the next thing will be to have the car plugged into Mercedes STAR diagnosis to check & clear the fault codes.
Let me know if you need anything else.
