Some advice please. When accelerating (overtaking on motorway), a plume of white smoke appeared from the exhaust pipes. When I took this into the dealer before, they kept the vehicle and exchanged the secondary turbo. Its now happened again. No loss of performance or other signs of fault. Any ideas?![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
