Moin colleagues, I have now had the problem three times that my T5 indicates to me “Decreased engine power” . The power also goes back noticeably. Once it went away by itself after 40 sec, otherwise it was off after a few hours. I have the feeling it might have to do with moisture because it has rained in any case. Do you have an idea? Are there any plugs or cable connections that like to soak up? VIDA for error code diagnosis is ordered but not yet there… Greetings Bulli
