SL 55 AMG check light and limp mode
Hello,
I have bought my SL 55 a few weeks ago and today was good weather to drive. I floor it on the highway and the car went to limp mode and the check engine turned on. I turn off the car and drive it again so everything is right. But still the engine light on and whenever I floor the car it goes to limp mode.
Anyone has been in this situation before. And what can be the problem. Note the car has just 32000 km.

hello there
Did you get a code for the accelerator pedal? Because I’ve got the same issue but without any codes!

If yup floor the car and it goes into limp mode and when restarting the car the issue resolved itself it is more than likely the accelerator pedal. It wears down the plastic and overextends causing an over voltage problem for the ECM. In limp mode the car doesn’t respond to accelerator input.
Shimming the pedal assembly so it doesn’t push down so far repairs the issue, as it isn’t necessarily a problem with the electronics. My sons car would do it every time he pushed the pedal all the way down. I glued a small washer right where the pedal hits the stop, and it doesn’t anymore.
