This is not good. Keep check on the oil. Find the oil leak. Fix the oil leak. With any luck you may have not trashed the engine. If the leak is from the drain plug or oil filter. go back to the shop that did the oil change. Seek recourse. Most likely you destroyed the bearings. Listen for bottom of the engine knock/ noise.

Many 2.0 TDI engines 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.

Hi...2008 gmc sierra crew...check engine light came on thought maybe was standard just before hitting 30,000 then noticed low oil pressure ( 20 ) then noticed clacking noise?


Sounds like an oil pressure problem. The clacking sound is most likely the lifters are collapsing due to loss of oil pressure. You may have a failing oil pump.

Oil Light comes on VW passat


Start checking the oil level, if oil is low then the problem is a leak or weared rings.

If oil level is ok, check that the oil pump has enough pressure.

If oil pump is also fine, then scan the ECU (car computer) and replace the sensor if you do not find anything else being wrong.

Low oil pressure light comes on and goes off


the noise is the chain tensioner in the cylinder head between the two camshafts. it is a job for a proffesional shop. the 1.8t passats had an oiling problem and were fixed with a larger oil filter. some times you have to remove the oilpan and replace the oil pickup tube.

2003 VW Passat Malfunction Indicator Lamp on


I have a 2003 Passat GLX V6 and i havent been experiencing this issue, however from my experience with VW, the early 2000 models of the passat that have a 1.8T 4 cylinder engine have a major issue with what has been deemed "oil sludge" you have to be careful with this engine oil wise and make sure to get the oil changed every 3,500 - 4,500 miles and make sure you get the full synthetic oils for it and the proper filters :-) the turbo that is on this model heats up the oil to extreme temperatures and if not serviced regularly you will have problems.... i hope this helps! i would have someone check it again for this issue... hopefully you get to it before it becomes costly!
