Re: LOW OIL LITE COMES ON WHEN RPM REACH 2000
Sounds like the oil is staying in the head
and not returning to the lower end fast enough
the oil returns are clogged and restricting the flow.
The fix for this is remove valve cover clean returns
change the oil and filter reinstall valve cover.

hi mate, my 55 plate passat did the same before major problems happened. first turbo went then the oil pressure light came on and the car went into limp mode. before its too late for you and a costly bill can you do the following. check if your car has a recall for the injector problems which vw are replacing under warenty. second thing the guy who repaired my turbo told me that these cares have a major fault which caused the turbo to go. the fault is the oil pump failure you must adress this issue as you can get a lot of info on the discussion forms. my car started with the same problem as you have described the pd engines have a design fault with the oil pump and shaft. this is common causing your turbo to go then the car will start showing oil pressure low please stop engine. educate your self via the forms and act quickly befor you end up with massive bills. i hope this has helped. trust me vw know about this design fault.you need to change your chain driven oil pump to the new gear driven system which vw have modified. all vag cars have the same problems be it audi skoda vw . my car had the same problem as you have said .started off with emissions then turbo failed thats when i started to investigate this problem . the pd engines was designed by some rookie at vw.
this case , you have to check turbo charger , when high RPM white smoke means lubricate oil goes to engine so give white smoke . on low rpm trubo close coming black smoke means no enough air gose to engine so this need to replace turbo . some type of turbo can be clean the wase gate ( which open with diafam beside turbo) make sure it's moving when accilerate. check vacum is ok . then clean wase gate > only some type have wings inside )if no replace turbo
VW RECKON that oil usage around 1/2 litre per 500km is acceptable !!!!!!!! yeah right...i suppose it does lubricate the turbo blades....and the exhaust pipe internally....you could use 20/50 instead of 5/40 that would cut it down,but not do much good to the engines long life..... VW reckon about 150,000m before rebuild.
CHECK ENGINE OIL LEVEL SOUND LIKE LOW OIL LEVEL.CHANGE OIL IF IT HAS BEEN OVER 3000 MILES OR OIL LOOKS DIRTY CHANGE IT.IF OIL CHANGE DONT HELP HAVE OIL PRESSURE CHECK TO SEE IF OIL PUMP GOING BAD OR YOU HAVE A FAULTY OIL PRESSURE GAUGE.
Idle is automatically set&monitored with a timing sensor on the camshaft, i found my engine(1.8 20v turbo) would idle low then go high and almost stall sometimes and all i did was remove the fat black pipe on the throttle and clean inside the throat with a cotton rag dabbed in wd40.Hold the throttle open manually and clean on and around the throttle plate as the oil burnt&recycled creates a hard carbon that stops the throttle working correctly.When did you last change the sparkplugs, air filter, oil and oil filter and remove damp from the spark plug area using wd40 on surfaces applied with a cotton rag.These contribute all to your problem.As you dont state milage etc it could be a worn engine or slipped cambelt(1-2 teeth can make a slight diffirence).
I had the same problem with my wife's 2006 passat turbo. We lost 2.5 quarts in 3000 miles and the warning light came on. They put us on a 1000 mile oil test and I lost 1.8 more quarts of oil. They finally agreed to replace the rings. Service tech told me that the factory rings are defective, they begin to lead after about 25,000.
