Sent my car in, one November for a routine campaign recall on hoses. Two months after that my check engine light came on. Then car started losing power, and I noticed a bit of noise under the hood. My husband, and I opened the hood, and checked all the belts, and could tell where this noise was coming from, but I did not want to drive it 30 miles to the dealesrship, so I had it towed there. Diagnosis was an alternator, and more! Had the most important thing fixed, they said I could come pick up the car; it was ready. Got to the dealership, the guy bringing my car around called my service advisor, and said the steering is hard. I Left it there overnight. They called me the next day with another problem, this time it was pullies, belts, and tension stuff. Then they hit me with this 3000.00 engine Kompressor, that needed to be replaced. Hey! this exquisitely made German car only had 43, 000 miles on it! what are you talking about a Kompressor for? I knew right then something was suspicious; and I told my advisor if they sabotaged my car, they have done it to the wrong one. I was so upset, I did not let them know I was on my way there. When I arrived, I told the service manager, I knew they sabotaged my car, to get more money from me, and I demanded to talk to the technician, and to see the belt that he took off my car. He found my belt, and brought it to me. It had melted off the pully; but no one smelled burning rubber, before they brought my car around for me to pick it up the fist time; nor did the tech? But they told me, they test drive the cars after repairs at least 4 miles, to make sure everything is working properly, before the owners pick their cars up. No one test drove my car, they just reved the rpms so high, in the shop, the pullies locked. I know this because my car's odometer reading was the same as when I took it in, as when I picked it up. And the belts were fine the day before I brought it in, and it had not been driven. I then complained to the general Manager, and I let them know it was not over. Guess what, after almost 2000.00 in pullies, belts, and coolant replacement, & a sensor. They repaired my car. I did not need a 3000.00 engine Kompressor. Only needed a waterpump, and in the end they ate that waterpump bill. I did not know it was the water pump until I read the end of service invoice. I was going to file a lawsuit as big as that company could hold, if my car was not repaired. It is running better than it was, when I first purchased it. It was thorougly checked by the General man, the Service Man. and someone else, before they called me to come pick it up. They were so gald to get me out of their hair. Since then I have not received any oil change notices, nor any other service notices since this happed. It pays to really be aware of situations, and how others can try to take advantage of you. It payed off in my case with this dealership. I know I am not the first person they have done this to; this scam was a well rehearsed plan!!!
