“While the vehicle is turned on but stationary (e.g. Stopped at a red light in light traffic) I began to smell diesel exhaust in the cabin of the vehicle. The odor was very strong and I had to lower the windows in order to breathe. The mechanic informed me that there was an oil leak near the turbo. I had to replace the fuel injector and leak line, in addition to all pipe seals at turbo.”
