They have good offers sometimes, and I have allways managed to got a time for service in quite…read moreshort notice.
Once they helped me in a small problem with my moped for free! Big thanks for that , but I start to think it doesn't compensate all.
I dont find ATU so cheap, as you might imagine. And last couple of times I have had a feeling that they try to put some extra work, suggesting to repair something that is not necessarily needed.
For last TÜV they said that a repairs about 1500EUR is needed for my Golf 4 (this included the timing belt change, that was needed I knew). Finally I got TÜV in other repair place for about 700EUR, including needed repairs, not the same all repairs (but including timing belt), you cannot compare the prices exactly, but meaning that I had feeling that ATU wanted repair more, that was necessarily needed. After 1,5 year later the car is still running fine, even without those extra repairs.
Again this week, I asked a estimation for repair in right front side, some of those pendulum support (koppelstange) and some stabilator. They would like to change both sides. I'm not saying that this is bad to change both sides same time, but not a must.
Now in other place, I got a information that something totally different is acgually broken.
I still will use their services in future also perhaps, but will ask other places also to compare the estimation of work and price. I dont trust them anymore fully.
