Very bad experience. Audi a3 had to get a software update because of fiddle software. This could be done by Audi flevo Harderwijk. The first appointment had gone well and I could wait for the update with a cup of coffee. But then it came to disaster. The car drove very badly and held on to the power. After the first start after departure at Audi flevo the engine management light started to burn. Called immediately after which I drove to Harderwijk as soon as possible and the car was examined. This lasted two hours before someone came to me and said that the throttle body was broken. And this could be replaced right away because they had it in stock (cost: 400 euros). The car had never had problems before. It is a coincidence that the part is now suddenly going. The part I have not replaced but the car drove the same as after I drove away the first time after the update. After some questioning, the best gentleman could perhaps tell from the update that this part was "broken". Afterwards, Audi flevo never called us back and after some bells from our side there were always excuses. After this bad experience the car went to a company, which the gentleman where we bought the car, advised to bring the car. The car has been returned to original state by this company. The car is now driving like a sun.After several thousand kilometers without "broken throttle body".
Completely abandoned by Audi Flevo Harderwijk so !!
