Where is the oil pressure sensor located at on a 2006 VW Passat 2.0 Turbo?

My personal suggestion would be
to go for these repair catalogs. I know this website www.reliable-store.com that i used to buy them from, and they sold online it was very good manual. Go ahead, I bet.

The 2.8 is not a turbo charged engine, so would not have a turbine speed sensor. The 1.8 or 2.0 were turbo charged.

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.

Need more clarification when driving and park. Happen to vw a lot with no solution. Could be electrical ( Tcm + Wiring conector, ECM) ( fluid change fluid+filter add lucid tray oil) or mechanical. Rattle could be engine or evap thing located under or next to air filter. Alternator also. The engine you speak of is know for sludge build up problems by VW. They've even made recalls base on what I've heard. Check oil circulation and how to fix oil circulation problem. Drop the the oil pan and clean filter screen where it sucks in oil. Other things related need to be unclog..

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

you have to remove the skid plate under the car to see it.

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.

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.
