Hello, I didn’t really know which forum I would like to put my question in, so please have a look, if it doesn’t fit 100 percent. I am a young woman and unfortunately I experience negative things again and again when I bring my car into the workshop, so I wanted to ask for your opinion, if I do wrong to the workshop if I want to ask a little more detail. Last week it was time again. The engine control light lit permanently yellow a uf, which caused me to drive into the workshop the next day and have the fault memory read out. Unfortunately, I no longer have the correct wording of the result in my ear, but it was something with flap position errors and something with negative pressure. An appointment was agreed and at noon the master then reported that the intake bridge had to be changed due to cokes. Cleaning was no longer possible. The car was then still 2 more days in the factory On the phone the master told me shortly before picking up that I had to refuel. There was not much fuel in the tank anymore, which surprised me very much, because the tank was still filled with 75% at the time of delivery in the workshop. This was due to installation and removal, as well as troubleshooting. Released petrol? Already then I asked myself why it was not refilled again? After all, the bill was so high enough to get angry. When I picked up the car, the mileage count was he resets and the tank just above reserve. Comparison of the odometer revealed a difference of about 170km. What do you say about it?
