Everyday I start my car in the morning at 7.25am and depart to work and arrive by 7.35am. The car is then parked and not started till my lunch break which is at 11: 30am. When I attempt to start my car at 11.30am the car will constantly attempt to start but takes atleast one minute of holding the key fully turned before it starts and then I see alot of white smoke exiting from the exhaust. I have had the car checked from a mechanic and they don't seem to understand why this is happening but suggenested the Turbo is leaking and this maybe causing a power spike. I service my car every 10k miles an replace the old oil, fuel filter, oil filter, pollen filter, air filter, anti freeze. I recently disovered that my car had been clocked back and the actual mileage is 267,000 Miles.
