Engine light on, heavy smoke and engine burning smell (Audi 1.8T)
When i drove my Audi 1.8T sport Auto (2001) on motorway, the oil pressure light flashed. so i stopped as soon as possible and waited about an half hour and added the oil. but when i started to drive , the light started to flash again. I sent my car to Mot and service. After the service, the engine light is on and when i started to drive, very heavy smoke and engine burning smell appeared. what the problem is?
i complained that the engine light , heavy smoke and engine buring smell appeared after service. The garage explained they don't know what caused the problems, but not because of the service. They stripped off my turbo and tried to send out to check but i have to pay, and they can't guarantee to fix the problem.
what should i do? pay to check the turbo? how much it will cost to replace the turbo?

Re: engine light on, heavy smoke and engine burning smell...
First off, how the Hell did they issue a DOT Cetificate, if the Emissions are known to be off the clock. Without causing stress, do you have, or can obtain the Emission Test Result Print Out from the Testing Station test Equipment. This is something they cannot refuse.

Their must be some oil stored somewhere and it is dripping on your exhaust manifold,but never pressure wash your engine, could cause worse problems,in time the smell will go away,just be patient.It will burn off in time.
Heavy use of engine oil and a nasty smelling smoke usually means the piston rings and cylinder bores are worn out or if you only get smoke on a closed throttle it can point to failed valve stem seals, (cheaper to fix but may point to other wear problems about to show up). The oil pressure warning light is not coming on because the crank shaft and bottom end of the engine are still (possibly) ok.
Sounds like a broken oil ring. As far as the engine stalling, if your really low on oil the motor will shut down so as not to damage any bearings and other internal parts. Does the engine seem to be turning over faster and taking longer to start than usual and take a little longer to stop when you turn the engine off. If so you could have an issue with the compression rings in one or more cylinders. Do a compression test. If the #s are near where they should be it's likley oil rings. If the #s are low it's likley the compression rings. Either way if its one of those issues you'll need to overhaul your engine
White SWEET smelling smoke, or white OILY smelling smoke? If it's white thick SWEET smelling smoke, you have a blown head gasket - that's the smell of antifreeze burning in the engine, which it should NEVER do. If it's white OILY smelling smoke (smells a lot like diesel), then you're getting too much fuel into the cylinders.
If it's sweet-smelling smoke (antifreeze), pull the oil dipstick & check the oil level. If the oil level is HIGH and the oil looks like a mocha milkshake, that's absolutely conclusive - that's what happens when antifreeze gets into your oil, and it's nasty corrosive to engine parts.
I'm not at all surprised that the oil light is on if it won't start - you won't get much oil pressure until the engine is running.
According to what you explain, there is some maf sensor defective or disconnected, the ferrari engine has high compression and forces the fuel to mix with the engine oil, this produces loss of oil pressure.
Check if the oil smells of fuel, check the sensor connections, also check the engine controller
could be sender or pump. do not run the engine until you're sure you have a good pump. Does it blink on and off--coming on mainly at idle? This would be normal for an old engine. If it stays on and the pump is bad, you will ruin your engine. You can try replacing the sending uniot, as that is cheap compared to the pump, but don't run it long to check new sender. If new sender stays red, shut down and replace pump.
