I have just acquired my 2016 SL63 and am very satisfied.

I have a concern/inquiry.


I returned from the dealership with the car's roof up - everything satisfactory. I stopped and placed many things in the trunk. I entered the vehicle and attempted to retract the roof, but the automobile indicated that I was over the speed limit, while being stopped.
I intended to check when I returned home, only a few miles distant. I subsequently saw many alerts on the dashboard. I departed, and after half a mile, the vehicle entered limp mode, exhibiting no throttle response.

I paused, and as the immediate shock subsided, I reflected on the changes I had made. I inspected the boot and discovered that the lid restricting the boot area was absent. I reduced this, began the vehicle, retracted the roof, and had no more problems.

This morning, it exhibited the same faults, but after the limit cover was reduced, everything functioned well.

Is this an idiosyncrasy exclusive to my vehicle or a common characteristic of cars from this era?

Any assistance will be very appreciated.

I can not see how the baggage cover might influence anything apart from the roof function; yet, I question if the speed sensors or reluctor rings are deteriorating. During a R class session, I had a problem where the vehicle displayed a speed of 1500 kph when stationary and was inoperable.

What error messages were displayed? Nonetheless, the dealer is accountable for rectifying the issue(s).

Thank you. I must clarify the content of what was mentioned. I will do more investigation in the morning and return with the precise mistakes if I can replicate the issue. I am aware that it seems to be resolved by adjusting the storage limit shelf into position.

Congratulations on acquiring an excellent vehicle! It seems peculiar that the boot lid would induce the vehicle to enter limp mode. If you have purchased from a dealer, it is their responsibility. Purchasing privately offers little redress, and I would be bringing the vehicle to a local independent Mercedes-Benz specialist for a STAR diagnostic. It is frustrating to get a new vehicle with issues, but I am certain it can be resolved. Speed sensors often malfunction in Mercedes-Benz vehicles, particularly with reluctor rings. Both induce a limp mode.Best of luck.

Thus, there are two individuals present.
