Hello, currently have a problem with our Grand Espace, year 2010, 2.0cdi 173ps as a switch. Already in autumn on the trip to the Baltic Sea after about 400 kilometers the message was checked at 120km/h. No power loss. As soon as speed and speed dropped, the message went away. After return from the vacation the message had disappeared after a few days. Currently on the weekend on the trip south to also about 400km the same game. Message came at 140km/h wied he, but also disappeared again. On the way back also after approx. 400km at approx. 150km/h suddenly at the hupen the message went on again and I immediately noticed that he no longer had the full power. Then tormented us the last 150km home, because mountain at max. 80km/h in the third gear. Where should I start now? Probably let error memory read out? Does this also make the ADAC? Did someone already have similar symptoms? Thank you
