Was driving on the highway and the car lost power. Took it in to the dealer and I was told that the problem cannot be duplicated. The car was in several times for repairs without success. Changed the egr valve to no avail. When the car looses power I have to restart it, and then is fine for a while. Bought the car new an sill have it.

The engine shut down by itself. I tried to restart, but it did not. However, it would start again, after 5 minutes. These events have happened several times; it became dangerous. Engine problems due to crankshaft position sensor failure.

Slowing down for light and car tries to stall. After getting it home and in the garage, noticed strong gas smell. Took to shop and guy said gas leak from top of tank. Read about lots of complaints about this issue with other people with E320's.
