I got this error massage every morning at cold start. (ONLY WHEN ITS COLD OUTSIDE, LOWER THAN 2-3 c°)
if i press the acceleration the massage and the service warming dissapears only for few secods..
But after 2-3 minutes the error its no more available.
when the car reach aprox. 5c° temperature everething its fine.
