Not enough oil pressure to run turbo keeps burning it out 99 passat 1.8

It will affect the car if it is burnt oil or you dont keep an eye on consumption and run low which will burn up turbo. I would suggest visiting www.tdiclub.com and reference your model there. The site is FULL of TDI experts and even lets you see if anyone is in your area. A lot of people like to work with these engines (TDI) and they have a big fan club. You might find a DIY person in your area that will help you pinpoint the problem better and help fix it at a much lower rate than a dealer. Remember OIL is the life blood of your car!

A bearing going bad. Do you follow turbo shut down procedures? If you don't have time to do this then my suggestion is installing a turbo timer to do this automatically. When you drive the car specially a high speed and need to shut down the engine is the worse thing you can do to your turbo. The impeller spins double the speed of sound and takes quite a while to slow down specially when you shut down the engine. At the same time it is shut down, oil pressure is no longer provided by the oil pump and cooking from extremely hot turbo assembly. The end product is oil carbonizing and clogging moving parts. The term is called coking. A turbo timer will keep your engine running when you remove the key from ignition and lock the vehicle for a programmable amount of time. This will help the turbo to spin dow while lowering the temperature critical for a longer servie life of your turbo charger.

Hi before you do an oil change try seafoam in the engine oil. this can sometimes fix the problems you are having, I used seafoam in engine oil and fuel and breather line and ran engine for 100 miles, but don't run hard, and its cleaned all the sump and oil veins in the engine, as checked with a scope looking though the oil sump plug. it did a really good job, my engine is a bit older than yours 1994. oil sensor is at the bottom of the engine on the sump. pressure sensor is above the oil filter it has a single wire conection

oil pressure should be atleast 18 psi @ idle on the engine however i think you have a weak/faulty oil pressure switch as well

good likely hood that your oil cooler is leaking oil into coolant this is something you want to replace as soon as possible. you will have to flush your coolant system several times to get as much of the oil out as possible. if you wait you will have severe temp issues as well as not heat due to a clogged heater core. and that is very hard to replace. To flush system hook garden hose to the larger hose of the coolant reservoir get car up to temp. keep idle up a little. get large bucket from the smaller hose that goes into the reservoir hook small hose to it and let it empty into bucket keep hose running thru all the time. before that though replace oil cooler. also replace coolant reservoir as well. or oil will contaminate new coolant. good luck

you "a" have a bad turbo,"b" left over oil burning off,& "c" a bad turbo for the whistleling. could be a bad blow off valve but not likely.

yes these suffer bad on faulty turbos, i think yours is dead, let me know how u get on.
i know they carbon up inside which stops the oil getting in, really u need another oil change between servicing.

you have to replace the turbo

If you are not driving far no problem. If you are just put a quart of oil in it until you get to the station.

If the turbo is truly failing, then it could put metal pieces through the engine if it broke apart. Usually when a turbo fails, it's the bearings wearing out, and the turbo starts making a "dentist's drill" sound when the car accelerates. $1500 sounds pretty steep but if it's at a dealership, I can see where it would cost that much. A better bet is an independent European car specialist - usually they'll cost significantly less. Also, you can source a turbo on your own (you'd be looking for a K03s turbo) and give it to the mechanic to install, to save even more.

If you're in New York State, I could do the job in my garage for you. I can source the turbo and do the work here.
