Hi all,
On my W221 S500L, after checking, I have the:
0271 - Continuous camshaft adjustment (RIGHT) :Incorrect position of the intake camshaft (P0011).

My local repair shop after opening and reassemble the engine, and found nothing about this code. However, after road test and the DAS rechecked, this code appear again, together with other following code:

0063 - Continuous camshaft adjustment (LEFT) :Incorrect position of the exhaust camshaft (P0024).

I've researched on the internet, and found someone had the same issue, and proposed to change the Camshaft sensor Y49/5 with another one (A 272 051 01 77 instead of 00 77). But, the final solution and/or result was not shown.

It is noted that the Camshaft sensor Y49/5 in my car is currently 00 77.

Anybody know anything about this?

Thank you in advance for sharing your experience and solution for such issue.

Timing related, but hard to say what exactly. The gears fail from time to time, but both sides is highly unlikely. More likely you have a stretched timing chain or something that could affect both sides, or a faulty M/E if the timing is perfect and the errors keep coming up. Can the cams be commanded back and forth properly via SDS?

Thank you for your reply. My guys tried to open/adjust, but these code still appear although no the check engine light. I am trying to order the Camshaft sensor of A 272 051 01 77 to replace as I found the Mercedes announcement of such issue happened to M272 or M273 Engine. However, I hope to receive further comment to resolve this issue.

Fault Code Scenario 2: One or more of the fault codes 0059, 0060, 0063, 0064, 0271, 0272, 0275, and 0276 is/are present in ME-SFI control module. The fault codes are recorded as current and/or stored in the fault memory. If current and/or stored, these codes are caused by a malfunctioning camshaft adjustment solenoid.

If both sides report timing issues you have a stretched chain.

Remove cam sensors and observe physical markings to see if they are apart. Your symptoms are very spot on unfortunately.

S500L_VN

Alx, thank you for reply. I will inform my guys to recheck it.

Actually, in my country, the dealer is not so good, both technically and commercially. So, I need helps from other repair shop and all of you in this forum.

S500L_VN

Just updated today from our guys that the Camshaft sensor of A 272 051 01 77 is installed. However, after road test about 2km, the CEL appeared, and fault code of 0271 was found.
Anybody can help us for next solution?
Thank you!

We're searching for several days if we can find the root cause of this issue, but failed. The car is normally running, but CEL still appears after some kilometers running.

The only thing we are thinking is if the guide (idler) gear of the chain drive on engine M273 will be checked and replaced.

Any help from you all is highly appreciated. Thanks!

Check that the engine is still in time, as per ALX's post.

S500L_VN

My Mech had checked it before changing the sensors, however, after about 2km road running, the CEL appears again.

I am still looking for the your helps before I agree for my Mech to check the guide (idler) gear if worn.

Thanks.

If the mechanic checked that the engine is in time already, then the balance shaft wont be the issue.

Do Not have your engine torn apart... I had the exact same issue. I was baffled just like you.
Then I changed my O2 sensors and haven't had a problem since.
Funny thing is, not one certified Mercedes mechanic could figure this out. Ended up buying a lot of parts I didn't need.

Good luck.

Michael Oliver

Eugene, Is that still working for you? I have a similar situation and timing is spot on according to the Dealer (runs fine and marks are dead center of Hall sensors). Of course, their recommendation is either timing replacement (10K) or new engine (10K). Both options exceed the value of the vehicle which is otherwise solid. What caused you to look at Oxy sensors as source? Thanks.

Wrong timing for few degree due to stretched timing or worm gears.idler will not create big impact to normal operation of the engine, for me I will fool ECU by moving camshaft magnet ring to the position (either earlier or restard...) It would be an easiest and cheapest way to eliminate CEL.

Eugene A Boxley

O2 sensors affect timingWith my situation, I was getting p0011,p0012, p0014, p0022 -25.... I rebuilt my engine twice and was getting the same codes every time. After changing throttle body and tps, maf sensor and magnets... Same crap. Finally, I came across an article that explains how o2 sensors can send your ECU junk data when they're going out. Changed mine (all 4) and no further problems. Bad gas, head gasket leak and bad oil seals will contaminate o2s....
​​​​ That's all I got for you, playa... Good luck 🤞.

HI all,

i have a w213 2017 Mercedes E63s,

Over the past few days I have felt there is a little knocking and jolting in the engine through the drivers seat upon cold start up.

To further limit any damage, i took it to get scanned to make sure there was nothing serious and 2 faults came up.

1 - P002477 The positioning of the EXHAUST camshaft (cylinder bank 2) deviates from the specific value. The commanded position cannot be reached

2 - P002177 The positioning of the INTAKE camshaft (cylinder bank 2) deviates from the specific value. The commanded position cannot be reached

The car has been ECU tuned to stage 1 by evolve tecnik

Just want know if anybody can shed some light on this for me as I was told by the MB tech he thinks that the reason as to why the adjustments are different from Factory spec is the tune.

Im a little confused as if so should it not be both banks not just the 1?

Thanks in advance

Sounds like you have a chain stretching or timing issue.

pete diegan

@Minh , "wrong timing by a few degree is OK"? My W204 had CEL due to 1208, and surely enough, looked behind the holes, timing is a bit off. On intake bank 1 (or bank 2), we know that camshaft could move between 4 BDTC and 36 ADTC. However, as long as my RPM goes above 3000, cam sensor shows 36.2 degree (which is one-fifth of one degree) then not only CEL turn on and cam monitor showing it stays constant at 36.2 (not fluctuating anymore) until code clear and process starts all over again. What was your specific fix to trick ECU, will it harm engine over long term?

Minh

There are a pin on camshaft magnet ring. Unscrew a bolt and remove this pin then you can rotate a ring on camshaft till you have correct value on camshaft sensor.

pete diegan

@Minh "There are a pin on camshaft magnet ring", you meant the camshaft adjuster inside--the pulse wheel, perhaps? As the camshaft adjuster solenoid (magnet) outside doesn't have any pin?

pete diegan

@Minh , totally agree with you; open up the engine is a waste when correcting the cam adjuster itself (or only the pulse wheel) takes much less work. However, did you have to open the top cam cover or just the front cover with a few bolts? You had to change the pulse wheel since it’s a single-use, right? Finally do you have to loosen the chain tensioner—which might end up replacing it as well?

Minh

No, you don't need to open camshaft cover to change a pulse wheel, just open front camshaft cover that would enough. Once front camshaft cover openned then you can remove a bolt hold camshaft gear and pulse wheels.

as you don't need to remove camshaft gear then you don't need to touch on timing chain and tensioner.

pete diegan

@Eugene A Boxley , almost agree with you that in many cases, MB techs are as clueless as anybody else! I got that experience with two dealerships around town here.

Now, P0011 (DTC 0271) and ended up with O2 sensors after you replaced a bunch of parts? Were you able to identify that O2 sensors had been the main cause; or simply a contributing causes?

My M272 is doing just fine, other than Intake bank 1 occasionally locking up at 36.2 degree advanced, despite CEL wasn’t thrown. Monitoring live data and today ran codes scan, for the first time I got this P0011. I am considering changing O2 as well after replaced magnets, sensors, wirings. I don’t believe that I had more severe issues such as timing chain or balance shaft sprocket wear.

hussein_abumaas

@pete diegan did you proceed with changing the o2 sensor? How did it go after?
