Had my SLK ECU reprogrammed about six months ago and the difference is great. However every now and then under hard acceleration the engine light comes on and it goes into limp mode. If I turn the ignition off and back on it exits limp mode but the light stays on.

Any ideas?

Thanks.

Yea your tuner screwed you----wait till the light burns out and your problem is solved

First thing is first..... scan the vehicle and post the codes. How do you expect people to give you ideas if they don't have any information!!!
