    Yeah I know about JPPSG lol..


    This one initially seemed like just another routine TSI chain job.. Not this time.. I know y'all don't really know me from a hole in the wall but I'm not one to ever throw parts at a problem without testing things first. I can't count how many I see come in that someone emptied the parts cannon trying to sort out something that ends up being a $50 fix at the end of the day

    If you can rev it and make it idle differently I would say it's definitely oil volume. Change the oil filter and see how it behaves if it's still misbehaving dropped oil pan check the pickup. If everything checks out okay pressurize the system and check for leaks. Don't let the engine warm up in the bay and then check oil pressure go out and drive it for 10 miles and then come back and check for oil pressure

    I forgot to mention check cam correlation before it warms up and then check can correlation after it warms up. If Cam correlation while engine is cold is good and it only falters after it warms up then you know you have the chain on right and you have oil volume issues

    The hole in the wall just isn't going to do it for me.......



    Let me follow up on my reiteration.........to proper lubrication guidelines.
    It's important to check oil beforehand & to get things fired up properly!
    It's further more important that it be flowing with oil not just an occasional drip!

    He says cold but yeah can be inverse on temp if a sticky issue causing too much PSI too.

    The cam correlation is off right from a cold start since it's choppy as soon as the idle starts to settle down (also sets codes imediately), and still off when at operating temperature. The more I think about it, the more I think it has to be a volume issue to the actuator itself. I know it takes a certain amount of oil pressure inside the actuator (8psi IIRC) to release the pin so it can adjust away from the fully retarded position. It's acting like it's physically stuck in the retarded position most of the time.

    oil and filter are fresh.. Liquimoly 5w40 is the oil that is in it, and a Mann filter.

    Unfortunately I cannot drive the car out on the road since it's a dealer's car and is not registered. There is a dead end road by my shop that's about a mile long that I can get away with driving on but that's about it. I can get the oil temperature up to near coolant temperature just holding the rpm up for a few minutes. The pan was reading 185F surface temperature when I checked the pressure before.

    My first step this evening is going to be pulling the pan to inspect for debris/clogged screen etc.

    - The values found in the Audi Volkswagen - 2.0L Chain Drive - P0016 Cam/Crank correlation check are correct, the values are from some of my old dealer training material and have been verified by my self several times, most recently last month on a 2011 Passat CC engine job.

    Silly question I need to ask, because I see no mention of it, but did you happen to look at the 'Camshaft Bridge' as mentioned in the correlation check forum post? See image ref below again....



    The screen must not be missing, damaged, etc... if so I would check the camshaft/head for wear and replace worn/damaged parts as needed.

    Hope that helps,

    OMFG..........

    Timing starts out at the FULL advanced position....... not the retarded for the retarded that think this.
    Second it seeks a retarded target based on oil permitted to change it by the solenoid.......
    The pin locks it in the advanced position to aid in cold start because cars start better cold with advanced timing not retarded.

    That is why when no oil PSI is exhibited the adjuster will display and over advanced DTC!

    Nice Post Peter............When will we make them understand?

    I think the screen was previously removed. the check ball is still in there but the screen and plastic surround are completely gone. I didn't see any evidence of leftover screen or plastic bits anywhere.

    I'll pull the bridge back off and double check for wear at the camshaft interface. Are there specs for the inside diameter of the bridge or outside diameter of the camshaft?

    This thing came from the auction so at this point I wouldn't be surprised if someone took the vanes out of the actuator.

    There's absolutely ZERO need to be condescending or to sit there and call me retarded.

    According to the self study guide, the cam locks in the retarded position. Is VW wrong?

    Kind of what my MVB 093.3 question is leading up to.

    All hail Tech Tip 01-15-08

    2008 - 2015 with those damn chain drive engines. P0011, P0016, P000A, P0341, and or P052A

    MVB 093.3 should not go over +/- 5 degrees. If so, suspect that the screen located in the camshaft adjuster bridge has come apart and lodged itself within the camshaft adjuster spool and the intake camshaft adjuster.
    blah blah blah... more stuff I'm glossing over now... ah, the last part of this Tech Tip...

    Despite the failure found, the repair should include replacement of the camshaft adjuster bridge, intake camshaft and the spool valve adjuster
    Poop just got expensive if not covered under some kind of extended warranty. At any rate, see if you can get yourself a copy of Tech Tip 01-15-08 (November 13, 2015) from your local dealer. I'd gladly give you a copy of mine, but legal reasons prevent it.
