STOP! Oil pressure low

Asked by Apr 18, 2015 at 08:06 PM about the 2004 Volkswagen Passat

Question type: Maintenance & Repair

Our 2004 VW passat keeps saying STOP!
Oil pressure low! We've had this looked at
multiple times and the mechanics can't find
any reason for the cause of this. They have
replaced a few things and it runs great for
about a week and then we get STOP! It's
very frustrating to have tor car in the shop
once a week/2weeks!!! The car has the
correct amount of oil in it. Why can't we find
the problem??

I can only assume they did a pressure check on the engine,that being said,if it is low oil pressure,then it will be a bad oil pump or internal engine problem,i would thing if it was low oil pressure they would have allready replaced the oil pump,but of this has been done,you may have internal engine problems,

This car probably has not had the correct specification oil used in it. An oil pressure check will show low oil pressure. The oil pan must be removed to inspect the oil pickup tube, which will be plugged with "sludge". Keep an eye for nylon pieces from the cam chain tensioner too; if present the valve cover will also have to be removed to inspect for cam tensioner damage. After this repair be sure to use oil that meets VW specification 502/505. You need to take care of this or the engine will become ruined as its being starved for oil.

I have a 2005 VW Passat Wagon B5 Edition. And I've come across this issue also. I've possibly found the answer... It's a failing Cam Tension Adjuster. When the engine is loosing it's timing, this is one of the errors that it can come up with. Ordereuroparts.com is where I'm getting the part, including the valve cover gasket and tensioner seal. And im getting a local foreign car shop to put it in. Total: $650 parts + $650 Labor = $1300 (Love It - The dealership was saying $2500 ($1300 same part + $1200 same labor)
