2006 vw passat

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.

You should perform an oil pressure test and see if the engine is producing oil pressure within specification. If it is, the lifters may quiet down over time.

STOP the engine immediately !!! There is an oil pump failure of 2.0 TDI engines !
Remove the oil pan and the oil pump & balancer shafts assembly.


Either the shaft driving the pump from the balance shaft rounds off or the balance shaft drive gears eat themselves.
The same issue ... low oil pressure warning light, noisy rattling engine, and the turbo has gone. Diagnosis: oil pump balancer shaft assembly ...



Many Passat show excess chain noise and wear anywhere from 50,000-100,000+ miles. Cars have broken the chains/tensioner as low as 65,000 miles. This is just a range of cars that have been reported, diagnosed, and repaired. The actual statistics on dealer repairs or failures is unknown and I've heard cars over 100,000 miles that, in my opinion as a non mechanic (most mechanics wouldn't recognize this sound and problem either), aren't noisy. From what has been reported, noticeable noise/chain-tensioner wear/greater risk of breaking is around 60,000-150,000 miles. Your case may vary. The most obvious symptom is a rattling loose noise from the oil pan. Unless you listen to a Passat TDI with a tight chain and one with a loose chain, it's hard to describe the difference other than rattling chain noise.
The reason the gear drive oil pump modification was started is because a few mechanics who specialize in TDI have seen many worn oil pump chains/sprockets/tensioners. There will always be a few defective parts that come off the assembly line and all mechanical components like chains wear out sooner or later, but in my opinion, the failure rate is abnormal considering the number of Passat TDI sold versus the number of reported oil pump failures. This does not necessarily mean that every or even most Passat TDI will have this problem, just that the reported failure rate is high enough to consider this part a design failure. Nobody, not even VW-Audi knows the average time between failure for these parts and the percentage of cars that will have this problem, but they changed this design and if you want to not have this specific failure, the only sure way is to swap to the geared module.

car needs oil pressure or bearings will wear out in short time. Do not drive or start engine with this light on. Might only be pressure sending unit. Can replace sending unit and start briefly to see if problem resolves. If light still stays on, shut off engine and have oil pump replaced.

Exhaust pressure sensor a possibility if it has a DPF (diesel particulate filter). Has it had its fuel pump recall, the oil pressure light could be just the constant cranking and running the battery low.

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.

8.5 hrs + parts sounds about right. But why would a 7 year old cars oil pump fail? They usually last a lifetime. Has there been a lubrication problem? Low oil, cheap oil, wrong oil? But then again my daughters 04 Toyota needed a valve job, head gasket and water pump recently. I'm doing 90% of work and it still cost about $2000. Her problem was bad oil!

I would check the oil pressure sensor and the oil pump itself. You can take the sensor out and use a mechanical gauge to check the oil pressure. If the oil pressure is within specs, you need a new sensor, if not, you need a new pump.

Just a idea. If the car is running at idle and the oil light blinks , it usually from low oil pressure. At a idle your seeing the light respond to the revolutions of the engine. ! thing to try is to replace the oil pressure switch on the engine block. And #2, Most causes in a VW is that the vehicle overheated at one time and weekend the oil pump,or massive amount of miles.

It sound as it your oil pressure senser or the oil pump needs replacing.
