Most likely, the seals around the compressor shaft have failed.
The cause for this is usually one of two things.
1) The MOST common cause is that people don't allow their turbos to cool before shut-down. The turbo rotates at upwards of 30,000 RPM, and is driven by exhaust (Very Hot). When the engine is shut down immediately without a cool-down, the oil that remains around the shaft and bearings cooks from the heat, and this causes seals to harden and the shaft to "coke" up. A 2 - 3 minute cool-down allows the oil to remain circulating at idle and cool the shaft and seals so that the remaining oil isn't subjected to the punishment of soaking in extreme heat.
2) Lack of maintenance. Oil doesn't get changed often enough, and many times isn't the type or classification recommended by the manufacturer.
After repair, make it a point to cool the turbo and be religious with your maintenance and correct oil.
Good Luck

if you have a bad turbo shaft seal(and ,contrary to what anyone else on here says, is the only way oil can get on the intake side of the turbo.), you will have a real real bad smoke problem. i mean real bad. if you are just getting oil into the intake side, it's entirely possible that you have a crancase blow-by problem, or a crankcase vent issue, and you are getting oil thru the vent hose from the valve cover to the air intake hose. a too high oil level will contribute greatly to this problem. check this all out before you believe a cracked turbo. if you have a cracked turbo, you will have a lack of power, and exhaust noise underhood. it will be obvious.

500 bucks to clean the intake manifold and turbo? Wow...that's righteous bill right there. No...it's not your engine it's your transmission. I could go into detail about ALL VW transmissions but I won't. Yeah...15w40 is probably not the best oil for your car...but I can't really comment on the needs of a turbo diesel. Typically you won't go wrong with 5w30 in all cars. I think toyota and some hondas recommend 5w20.

Seals are gone in the turbocharger. That is caused by excessive play in the impeller bearings allowing the seals to leak oil.
Rebuild or replace the turbocharger..

this is a problem that should taken care of asap you have more than likley driven your car at high rpms before the oil gets warm or you drive at low speeds at low rpms the later causes low oil pressure not lubing te bearings in the turbo if you see white smoke from the exaust you will need to replace the turbo GOOD LUCK

Because your turbo is worn out. The bearings and seals have too much clearance between them and this letting oil pas by.

The seals in the cartridge are leaking most likely caused by excessive shaft play.

The dodge man is right, it's a bad gasket or crack in the housing of the turbo.
