P0011 Help

Anyone have experience with this code? I had it show up a year or 2 ago on my GTI. Cleared it and it didn't come back so I thought nothing of it. Had the CEL pop on Monday morning when I left for work. Came on right after I started the car and it had been sitting all weekend. Car was running just fine so I wasn't too concerned. Still threw on my OBDII Bluetooth adapter when I got to work and scanned. Got the P0011 code. Cleared it and all was well, or so I thought. Came back on this morning so looks like I have some troubleshooting to do.

I haven't hooked VAG-COM up yet. I didn't clear the code today so I could throw that on tonight. I've done a little researching but pretty much every post I see about it, the car is running poorly or making terrible noises. My car is running no different than usual, no bad noises.

I have 143k on the car. I am due for a timing belt (was done at 90k in the winter of 2009) and was planning on getting that done this fall. I'll be checking the timing marks tonight for sure. I've also had it suggested it could be the cam chain tensioner...any good way to check that? Any other thoughts on things to check? Good VAG-COM tests for components?

Thanks :D

I just am at such a loss because the car runs great! Hoping VAG-COM will shed some more light on things...
Lots of threads; point to the cam chain tensioner failing. Is the top end/valve cover area noisy? I worked on a 1.8T Jetta; I believe was throwing a similar code and the tensioner failed, it was really noisy, chain rattled all the time. This "rattle" sound; is usually heard on initially start up and then goes away, because the variable valve timing tensioner, works with oil pressure. When the car is first started in the morning; the oil pressure is low and when it starts, it pumps the pressure back up (then, the sound goes away). If the rattle is there all the time; that is a pretty good indicator, the tensioner is bad or you may have a clogged oil pickup tube (sludge).

Other threads; say to check the timing marks and see if everything is in sync.

One thread; seems to narrow the possible problems to:

(1) Cam chain tensioner
(2) Sheared keyway on your crank timing gear causing the car to go in and out of time.
(3) Cam pos. sensor.

The cam adjustment valve checked out ok, per the Bentley specs. Scanned with VAG-COM, no other codes (other than my 17705 code that has also been perplexing me, as I only go into limp mode once the code is cleared. If the code is stored, no limp mode! But that's for another thread). There is a slight ticking on cold start, but my husband used a mechanic's stethoscope and it sounds like its coming from the middle of the engine, between the first 2 cylinders (from the timing belt side). It does quiet down once the car gets warm. But its not something that I notice all the time and it doesn't seem to be coming from the chain area. Oil is in good shape - no sludge at all and color is normal. Running Castrol Edge 5w40.
Have you tried the measuring block(s) testing for the chain tensioner; they say there is a "system/ok" field, that tells you if things are working at they should (blocks # 90-94?).

A output test; would also, show if the N205 is working (should make a "click" noise).

Good video here: (in this case; the N205 was working but the piston/adjuster was seized)

Any updates?
Haven't had a chance. My husband has been working crazy hours this week so my extra set of eyes/hands/ears hasn't been able to help me out. So far, no CEL again. We'll see if it comes back tonight or over the weekend. But I'll still check into the N205 some more.
