hi I have a 2004 e55. I just had a tune done. but my issue is the car will not go past 100 mph. as soon as I get to 100 the car cuts out power like I hit the speed limiter and I get a message on my display telling me Distronic limit reached. when I put the car in Dyno mode the car drives fine will do 160 mph without an issue but I lose all my computers on my benz. abs esp ect. anyone have an idea with this. I really don't want to take my car to the stealership.

 

Who did your tune?

 

Was it fine prior to the tune?

Talk to the tuner...

 

sounds like your driving with distronic turned on, the tune would not cause this.

 

What does distronic do exactly? Only option my car doesn't have...

 

Alek from logic lab tuning did the tune. it was doing this before the tune so that's not the problem. distronic is like adaptive cruise control. it senses vehicles allowing the car to slow down and speed up. i think it may have something to do with the distronic module.
