 directly after the expiry of manufacturer's warranty, the turbos failed. They fail unexpectedly so, if I am on the road, the car will suddenly lose turbo power, and, despite engine revs rising, nothing speeds the car over 40 mph. The car has spent more time and I have spent more money in repair shops than I spent on a smaller car I have as well, which runs flawlessly. I had believed that, after having spent a small fortune purchasing this car, I would not need extended warranty, but I was wrong! The help I received from Bavarian was no help at all. I was offered a $1000 discount on my next purchase of a Beamer!  I wanted to have some diagnosis, but all the diagnostics have been steadily repaired and the same problem recurs. I wonder if the car was made to run in cooler weather, as it runs hot and may have caused damage to the diagnostics in the computer, which is the more expensive one to replace
