I to have been taking my Passat 1.8 turbo engine to the dealership for all my oil changes. According to the invoice the dealership uses Castrol 10W30, which is not the recommended oil. I have 45,000 miles on my car, and the engine has developed a sludge problem. The problem is so severe that the engine needs to be replaced. Volkswagen refuses to pay for the repair because I missed one oil change. But they failed to tell me that they were not using the oil that is recommended in the manual. This surprises me that the authorize dealerships do not follow the manual recommendations, but holds the owner responsible for this error.

I would call VWoA customer service and report your problem. So, you went 10K miles between oil changes once?

I guess my point was not that Walmart sells Mobile 1. I realize Mobile 1 is Mobile 1 no matter where you buy it. I just thought it was odd that a Bentley Dealer would be getting there oil supply from a Walmart and not through buying in bulk.

Oil Pressure Indication in DIC by desertrat5
Dec 10, 2004 (6:22 pm)

I have both a Buick Ultra and a Pontiac Bonneville SLE. The Buick forum is not very active and I have not received any feedback on the Pontiac forum which is fairly active. So I am posting my question here.
I just had a LOF and engine detail on my wife's 2000 Ultra. Now the DIC shows 129 psi oil pressure regardless of engine RPM. I have never seen it that high and I have never seen it rock solid unchanging. Is it possible that water from the engine detail has messed with a connection somewhere (all the other DIC indicators seem to be working okay)? Or could they have done something in the oil change to make the pressure that high?
My 04 Bonneville SLE has a gage which typically shows between 60 and 80 psi oil pressure. The gage does sweep from 0 to 120 back to 0 at startup before registering the actual pressure.
  
Thanks in advance for any info.

If water gets into the connection at the pressure sending unit you can get a short to ground and peg the reading low, or open and peg high. At least I think that is the way it swings. Been a while, but I saw this before on an Olds engine. Find the pressure sending unit and make sure the connection is dry and tight. The DIC can only display what it is receiving, or as we have said about computers for years ...

The other interesting item is that the DIC also says "Normal" right next to the 129 psi reading.
 
Is there a check valve in the filter that could be plugged and drive the pressure that high? I know some filters have such valves to keep the oil from all running out of the engine after shut down.

my oil change story by scottinky

I took my 03 Pathfinder to my dealer to have the oil changed yesterday. Picked it up in the afternoon, drove it home. Went out last night. Upon returning home, noticed a big puddle of oil in the garage. I didn't see it when I left, but it was there. My round trip was about 6 miles. I turn off the motor, and watch oil drip from the filter location. Crap. I pop the hood, check the stick , I have maybe 1 quart of oil left. So, I add 1/2 a quart of what I had in the garage, and pulled in. This morning, all the oil had drained out, no surprise. I call my dealer and inform them of what happened. My dealer rocks! Sure, they made a mistake, but my motor didn't blow, whew. within an hour, I had a flatbed tow truck, and a guy from the dealership at my house with cleanup supplies and a rental car. Unfortunately, i won't get my truck back till monday cuz there are no mechanics there. However, this dealer has always taken care of their customers, and I am amazed at the service. The general sales manager took it upon himself to take care of the matter. All I can do now is wait and see what the problem was.
