Destroyed our transmission. Avoid at all costs! We bought our BMW X5 4 months ago from a certified dealership, with all diagnostic test completed. We took our car to Cardan for a simple oil change. When we got it back, it leaked visibly dripping oil and created a huge puddle in 10mins. We immediately took it back to Cardan, where they “fixed” it again. A week later we realized it was still leaking (less rapidly this time) and our car wasn’t able to accelerate properly anymore. The transmission light is on and our car is undrivable. Possibly messed up a completely healthy car part due to the oil mistake. The owner of Cardan is out of town for a month (vacationing in Iran), as he often is. Safe yourself all this trouble and take your car literally anywhere else!
