Sudden power losses appeared. Often it helped to restart the car - but of course not acceptable. Garage first replaced Lambda sonde, but this did not solve the issue. In the end, a throttle valve (or somethin like that) was replaced. NOTE: in the end the garage searched for free, checking and cleaning all electric contacts which did solve the problem!! Oooofffff, cause I really like this car UPDATE 1/10/2017: The number of power losses reduced, but the problem is not solved yet!!
