01 740i - Code p0011 "Camshaft position timing over-advanced Bank 1...what now?
 
My 7 is making a rattling noise. Here are the notes from my diagnostics test:

*2001 740i 170k miles*

Code p0011: Camshaft position timing over-advanced bank 1, "rattling noise in engine sounds like timing change, suspect that hydrolic chain tensioner has lost tension causing slack in the chain"

Est $450 to verify

Any suggestions?

I would suspect a VANOS failure. Here is a sound of a VANOS:

Here is a failed timing guide :

Thanks joyism5!

It definitely sounds like the VANOS.

I will post a video of my car later today. Any estimate on the cost to repair?

Thanks again.

Here's a DIY on changing out the timing chain tensioner. It costs about $90 from the dealer.

One VANOS unit is around $500, since you are in there few things should be changed, like timing guides, OSV, timing gaskets... Parts I would say around $800 + VANOS $1000 and the labor around 25hours. If you are handy you might manage yourself....Yeap, not cheap. either way.

Sounds more like guide failure?

joyism5 07-27-2012 09:22 PM

I will be inclined to think the guides since you have that code. Vanos, usually sounds like a diesel (a deep sound). I would remove lower oil pan and check for broken plastic pieces. This way I will rule out the guides.
However it could be a hydraulic lifter also. Check this thread down the page http://www.bimmerfest.com/forums/sho...d.php?t=631099

Great post about the HVA. I started the bleed process and noticed some smoke from under the hood.

Is that common? I was a little concerned so I stopped.

My experience is similar to yours. I needed an oil change bad. Just relocated to a new city.

I got an oil change, he put "VS5w30" in my car. I then proceeded to drive 200miles for a business trip. As soon as I reached the hotel that night my check engine light came on and engine ticking began.

Any thoughts?

5W-30 is too thin for an engine with 170K. My opinion. Smoke is not good, unless is coming from exhaust pipe. Maybe you have some leaky gaskets and is dripping on the exhaust manifold. I would pay more attention next time, to see exactly from where is coming the smoke. Also you can buy a mechanics stethoscope($10) from NAPA or SEARS, and locate better the noise: top on the engine, front of the engine/timing cover, pass side or driver side. At 170K miles I would use a heavier oil. I see you are in NC, you should be fine with it almost year around. I have used Mobile 1 20W-50 with great results. The oil consumption was reduced a lot and the engine got quieter for a few thousands miles. It cost around $10/qt usually available at O'reilly. The VANOS noise that I had it went really off when I changed the seals. That took a lot of time and work.
Remember to check the oil level often and make sure you have the right level before you start the bleeding process.

I agree. I need to start buying the oil you suggested. My value gasket is leaking according to my diagnostic test.

I replaced the coil recently. That could be the source of the smoke. I found a good indy shop here in NC. Taking it there soon.

Let's see how it goes....thanks for your feedback.
