Air mass meters

Hello, at my 9-3 SC TID (150 hp) the night before yesterday the engine control light started. After that the car had no more power. After several kilometers on the country road (I somehow had to come home) the power was suddenly back at a traffic light and I could drive normally (lamp remained on). Yesterday morning again lamp on and no power. To the friendly. He then said that the air mass meter was defective. In addition the fan control Not all right, but they don’t find the cause. At all tomorrow (that is today) business holidays, he can’t order the part, because nobody can reach it at the earliest next year. If someone has had problems with the air mass meter here, I can’t find any entries in Fred. Hope someone can help. Otherwise, a good slide to everyone (but please not on the road ;-)).
