A little white/blue smoke at startup is usually an indication of valve seals leaking a little. If it's only at startup and goes away, it's not a big problem - keep an eye on the oil level in the crankcase (dipstick).
If it's dense white smoke, and continues for up to a minute or so (or longer), you may be getting coolant into the cylinders - head gasket or worse problems. If this is the case, you may want to have it checked for contamination of the coolant by exhaust products.
White smoke out of the exhaust indicates moisture (water) in the exhaust. If the car is not driven very far each day, some moisture will collect in the muffler and cause white smoke for a short while after starting. If the smoke is continual, however, you need to watch you coolant level as you may have a blown head gasket.
its time to look under the car yourself for a oil leak or even a plastic bag burning on the exhaust you have been checking the engine oil have you checked the transmission fluid level? the trans is on the drivers side i believe
Turbo is bad, when you start seeing black exhaust turbo has gone out completely. Depending on how old the turbo is and how hard it is driven, how many miles and so forth.
If you have a head gasket problem, you should see dense white smoke coming out of the exhaust pipe if you have antifreeze (ethylene glycol) in the cooling system, especially right after starting the engine.
If the engine is using oil then first remove the dipstick and run the engine, check to see if heavy smoke is coming out of the tube, this would indicate worn piston rings,if it is not so dense, yet you are using oil and it smokes bad from the exhaust, then its likely the valve seals are worn. either way, unless you have mechanical knowledge, tools etc , you need to take it to a mechanic for the engine repairs or live with the oil consumption. There are no quick fixes for engine wear.
IMEDIATLY CONTACT WHOEVER DID THIS SERVICE, AS IT IS OBVIOUS THAT THEY DID NOT FILL CRANKCASE WITH PROPER QUANTITY OF OIL AND IT HAS CAUSED MAJOR DAMAGE TO YOUR ENGINE
have you driven it at least 100 miles since repair?, the oil residue builds up inside the exhaust and burns off very slowly from the previous failed turbo seal.
Dense white smoke usually means coolant is getting into the cylinders -- usually a head gasket. You're fortunate if you have dual exhausts and are only getting the white smoke from driver's side. You know which head gasket to check/change. Unless the leak is minor, you can usually determine which cylinders are affected by doing a compression check.
