Hey Scotty. First off your videos (specifically youtube here up to this point) have helped me a lot for my first time actually getting under the hood of a car. Thank you. Secondly I bought an 07 vw passat wolfsburg edition with a blown turbo. I put in a new turbo, complete oil change (twice now). I have been driving it about a month and while it always idled a little rough for my liking, it ran fine. Now it started giving me sporadic "low oil pressure warning" shrieks while warning me my cars life is in my hands. Then it gave me a check engine light. It still drove ok but i took it easy on my way to and from work while i tried to diagnose the issue. Got codes read on it and I got P000A Intake Camshaft Position Slow Response Bank 1. I'm going cross-eyed with the number of possible issues I might be looking at. But I'm going to try replacing the camshaft position sensors and see what that does. Now, If I let it sit a couple of days it will run fine for about a day with no check engine light or oil pressure warning but will start shrieking like a banshee come night time (I deliver pizzas as a second job at night) when I start putting some consistent time in behind the wheel. However there doesn't seem to be much of a pattern (I tried intentionally tripping the warning by varying rpms however this didn't yield anything conclusive but it does seem to happen more often at 30+ rpms). I did not replace the feed and drain lines to the turbo since they looked ok and frankly I didn't have the time to wait for them. When I did the oil change it became pretty apparent that the previous owner didn't maintain it all that well (the oil filter cartridge looked like it had been squeezed like a soda can and the oil redefined black [when i bought the car I just chalked it up too burning oil from the blown turbo (didn't think that one through in retrospect)]). This is the first time I've done anything greater than changing the oil but I want this win badly. Any insight would be much appreciated. Thanks again.
ok, thanks again.
low oil presure will make cams go weird in that VVT system, realize that. You have to fix that first, and being a VW, pray damage has not been done to the engine internally. Me, I'd rethink the car choice myself, a ten year old passat is a money pit waiting to swallow you
