    2006 Audi A4 2.0T FSI P0016 Loud Rattling/Clanking Noise

    Car: 2006 Audi A4 2.0T FSI

    Problem I am having:
    Drove the car to the store, no weird noises car drove fine. Leave store 30 minutes later and a few blocks away I hear the engine making weird noises. Almost sounded like a rattling/loose heat shield, with revving the engine to 2,000 rpm made sound go away. When I got off the highway the noise was worrying me again. Pretty bad sounding, but I figured if I made it this far it was best to just get it home. No check engine/MIL light. Get home scan the car, have a soft code for P0016. Clear the code. Start it again and I am getting a loud rattling from what seems to be the cam chain cover on the back of the motor. This is the video I took at that time. (https://www.youtube.com/watch?v=xXFHV4F1rVE). Revved the motor a couple of times and kept the RPM's steady above 2,000-2,500rpm and the sound seems to go away. This time I get a check engine light. Scan the car again and get 1 code on a full scan relating to the engine.



    I have gotten the P0016 code a few times over the past year, clearing it wouldn't have it resurface for months at a time. I decided to go ahead and buy a new cam chain tensioner, chain, cam follower, and tools fearing that the tensioner may have had enough and probably was destroyed. Finally got around to working on the car tonight. Got everything off and to my surprise the tensioner did not look bad at all, chain looked fine too. I did have a tough time aligning the tool between the two cams to lock them so I can remove the polydrive bolt holding the cam adjuster on. It was a tight fit and removing it I had to rotate the exhaust cam slightly to get the tool free. With the motor at TDC the intake cam adjustment slots point straight up and down 12o'clock position while the exhaust cam adjustment slots are rotated to about 2-3 o'clock position. Replaced the tensioner, chain, cam follower, cam tensioner case gasket, valve cover gasket, replaced the three seals on the cam adjuster that is part of the cam chain cover (stock seals were fine) and the polydrive bolt. Did not notice anything on the oil passage screen on the old tensioner. Cam follower looked pretty good too. The only time this side of the motor was opened was when I had my intake cam replaced from Audi under the extended warranty around 110K miles, car now has 195K miles.

    Once I got the car all back together after replacing all the parts, started it, slight noise for the first 2-3 seconds until oil got to the cylinder head I'm assuming, then the sound went away. Ok great that solved my problem. Then once the engine RPM dropped back down after the cold start the noise came right back. I am lost as to what it may be. Something tells me it could possibly be the cam chain adjuster, or the cam adjuster control valve (n205), but I am not 100% certain that either of those would cause this kind of noise. Judging by the fact my cams do seem as they are somewhat out of sync with each other because of the trouble I had installing the tool is it possible the chain jumped a tooth?

    Post an auto-scan please.
    Sounds like internal oil issue, with, sludge or fuel in oil taking toll but could also be worn components too?

    Here is the autoscan. Cleared the P0016 code and rescanned after revving the engine in my driveway it returned. Noise from engine, which I am almost positive is coming from the rear cam chain cover area since I used a mechanics stethoscope and it was the loudest from there. Revs over 2,200 rpm and the noise is very faint, no nearly as loud as idle. After a few sessions of holding revs over 2,200rpm and letting it drop back down to idle (10-15 minutes), I shut the car off and cleared all the codes from all modules. Restarted the car and other than the normal rattle when a car is first started until oil makes it to the head, it has been sitting idling here for 10 minutes with ZERO noises. I am afraid to raise the revs a little now cause I think the noise will return.

    So let the car idle for 35-40 minutes after the noise stopped on it’s own. Blipped the throttle a few times getting pretty close to redline and no problems what so ever. Check for codes, none. Right before I was going to go for a drive I heard the noise slowly coming back, checked for codes and there was the P0016 code. Blipped the throttle again to about 5,000rpm and the noise went away and stayed away, cleared the code, took it for a 15 minute test drive and the noise never returned. Got home, turned the car on and off a half dozen times in the driveway and no noises, no codes. Is it possible that the N205 valve or the VVT cam gear can be sticking? Causing this noise and problem? Cause I was told by a VW tech that the retard/advance on the VVT is only a couple degrees but it’s almost as if you’re a tooth off on one of the cam sprockets.

    Didn’t notice a broken key way on the cam adjuster when I had it off yesterday.

    Also I’ve already seen what is in the wiki about the code but sadly none of the things to check/tooth spacing seem to be for the 2.0t fsi motors. Drove the car to grab dinner just now. No noise, drove fine, no check engine light.

    That's what the RTFB is for and you better check crankshaft key and can sprocket.
