    Fault Code P0011

    I am getting a fault code P0011
    Intake Camshaft-Position Timing- Over Advanced (Bank 1)


    Is this a easy fix and has anyone run to a problem like this?

    Is it an easy fix? Most likely not.

    Has anyone ever got this error code before? Absolutely yes.
    You can search & find quite a lot of info on P0011 codes here on this board.

    Most likely the problem is the timing chain guides have started coming apart & the excess slack in the timing chain has caused the vanos timing to be off.

    A very good way to tell if this is your problem is to drain the oil & drop the oil pan (this is a pretty easy thing to do, it's just quite a lot of 10mm bolts that you'll need to loosen to drop the oil pan). Once the pan is dropped, look for bits of the timing chain guide rail in the bottom of the pan. If you find them, you'll need to have the timing chain guides replaced. This is quite an expensive repair to have done (in the scheme of repairs our cars will need).

    If there are no bits of broken chain guides in your oil pan, then I'd GUESS for some reason you need your vanos timing re-set. Why? I have no clue myself. But, I guess that could happen.

    I'd suggest you search on P0011 here & do a bit of reading to see what you're up against.

    I would recomend that you do not drive your 7 anymore until you get that P0011 code resolved. If the chain guides have started to come apart, I've seen & read about engines where the timing chain has broken & that caused the valves to his the pistons & bend (the valves). Then we're talking about even more money to fix.

    I dont know how mechanically inclined you are but you could do the job yourself. A timing guide kit is $295 from oembimmerparts, that doesnt include a chain which is another $145 but when I did the job, I just reused the same timing chain. But you'd also need to buy some gaskets and you'd want to replace the cyclone oil sep which is about $30 so figure $400 and a upto a weeks time. You'd probably need to time the Vanos system too which would require some special tools although one board member explained how he made a set himself.

    There's a writeup in the DIY section that shows how to do it

    But hold on, dont go changin those guides yet. Its not guaranteed its a timing guide or a vanos unit. The P0011 can be caused by a bad vanos solenoid.

    I got a similar code of P0021 or P0022 after I did my guides and all I had to do was retime my vanos and I was fine, however, in the process of searching for info for the P0021/22 codes I stumbled across this for a P0011 code. The guy that wrote these instrux in somehow involved with Beisan Systems which sells Vanos repair kits but not for the E38 yet.

    Here's what he says about a P0011 so try it.

    Here are the things that can cause P0011
    Aftermarket camshaft position sensor
    Failed vanos seals
    Sticking vanos intake solenoid piston
    Wrong engine timing

    Remove the vanos intake solenoid. You can use a 32mm open wrench to break it free. Under the solenoid is a red spring loaded piston. Press it in and release. Do this several times and see if it's sticking. Take it out and spray clean it and its cylinder with brake cleaner. Dry them, lubricate with oil, and reinsert the piston. Check the piston movement again. Reinstall the solenoid.

    Give this a try although dropping the oil pan and checking for bits of plastic might not be a bad ideal to do as well

    Can you give me the link to the DIY please? I did find some metallic bits in the oil filter when I changed the oil today...is that a sign?

    Thanks

    From the DIY post at the top of this forum:

    http://forums.bimmerforums.com/forum....php?t=1619734

    Much more info if you're interested can be found by just doing a search on this board for P0011.

    Bits in your oil filter isn't good. If nothing else it's bad news for the engine.
    I still suggest dropping your oil pan & finding out where your engine stands....

    i wouldnt pull anything yet...

    do you hear the unmistakable sound of 'vanos rattle',,(which is often confused as bad lifters, except the sound isnt metal to metal, its metal to plastic,, slight difference.

    and correct me if im wrong, but if you never hear the vanos rattle, then why pull the pan?,, and yes checking the filter area is a GREAT idea first too.

    i agree, dont drive it until u find out for sure, but if you have NO vanos rattle, chances are good that its not the chain guides falling apart.

    like blacksport said from what he found:
    Here are the things that can cause P0011
    Aftermarket camshaft position sensor
    Failed vanos seals
    Sticking vanos intake solenoid piston
    Wrong engine timing


    the timing isnt wrong if the engine runs ok/decent, and you have no vanos rattle. the only way it could jump time is if the chain guides were completely trashed,,,in which case you would hear the rattle, and it would prob have f*** up the engine by now.

    best of luck!

    the po11 code indicates a Vanos timing issue. Not a motor timing issue. Vanos can go out of time without destroying the valves. It can be caused by internal wear or too much slack in the chain. I currently have a motor apart that has a disintegrated center rail. It still turns over without hitting the valves, but the vanos units are out.

    Hi guys,

    My car(2001 740iL with 80k mi) has the same P0011 code. I recently(less than a 100mi ago) got the oil pan gasket changed, there were no pieces there just oil and some gunky buildup. There are no diesel like or tapping noises when i start the car or when driving. The car drives perfectly fine, no hesitation, no smoke, no noises, no rattle. I am using the following thread as a reference for how the engine sounds before and after the timing chain guide problem.

    http://forums.bimmerforums.com/forum...ighlight=P0011

    My car does not have the timing chain rattle sound.

    I am really hoping that it will be something like the cps or vanos solenoid or the timing chain tensioner. This thread gives me some hope. I desperately need some expert opinion here.

    One question. nobody seems to mention the timing belt tensioner in relation to this problem. I would think it has to be related to the problem but i am no expert. What do you guys think?

    roblo: what did your problem turn out to be? did you ever get it fixed? What was the cost? Thanks.

    I have a 2003 2.5 z4. I just changed the spark plugs and was running great. It started a small misfire and became more frequent when driving. Then I was reading and got some file system
    cleaner to put in it. The coils are good. Cylinder 5 is misfiring now and I also got these codes

    Hello everyone,
    I'm new to the E38s forum ( had an M3 before I divorced ;-).I just bought an imolared 2001 740i sport. Went to autozone to check on the "service engine soon" and got the following:

    Troubleshooting POO11
    "A" camshaft position-timing over-advanced or system performance- bank 1
    Explanation:
    Camshaft actuator failure
    Probable cause:
    Mechanical timing condition


    After a lot of reading, I'm scared...
    They cleared the code and I drove the car for about 120 miles and I haven't seen the engine light again; but i wonder if by replacing the camshaft actuator with an OEM one would take care of the problem or I should start saving for a timing chain guides job.
    They car drives fine, but I do hear a def knocking at times...I've been thinking about doing an oil change and put Mobil1 0W40, which is the one I've always used in my previous bimmers....and see what happens.
    Thank you in advance!!!

    Welcome here. Not really qualified to answer your questions but hope the code does not come back. Rarely see a good story with that particular code.

    Kind of weird, but my code comes and goes...like I don't even need to reset it with the tool... I drive for a couple of days and all of the sudden when I start the car there's no CEL in my dash.

    Im getting used to the car so I dont know if this is the normal situation or everybody once they get a code and the CEL, they stay there until the problem is fixed.

    I got the P0011 code on my car a few months ago. There were no symptoms with the code, the car was running just fine, no rattle, no hesitation, no weird noises, nothing in the oil pan or filter, no loss of power nothing.

    I started with the cheapest component, my primary suspect was the CPS. So went ahead and changed the CPS. Also changed the timing chain tensioner rod that goes in the UTC (real simple to do) as a precaution. Cleared the code. Its has been almost 2k miles and the code has not come back. So I am suspecting the CPS was bad. The weird thing is that I have not read any post where a bad CPS was throwing a P0011. BTW I also had the light coming-and-going symptom.

    Interested in knowing what you find.

    The vanos solenoid (goes in right below the CPS) is also known to cause the P0011 code. There was a post where an improperly connected vanos solenoid (after a VCG job) was causing the code. The code disappeared after the connector was reconnected. The vanos solenoid was around $250 at the BMW dealer (Phoenix AZ) a few months when I checked.

    ^ I had the same symptoms. It was the CPS. Switch the left and right sensors to see if the code switches banks.

    NOTE: If the insulation comes off exposing the wires inside, REPLACE THE SENSOR, even if it isn't the suspected one. It'll blow a fuse for the DME (ECU)
