Got the CEL on today. After checking with my ODB cable it appears the error is P0106. From what I gathered on the net, this does not seem to be a big thing, probably a line disconnected somewhere.

Is that right or do you have other ideas ?

 

I did reset the error on tuesday evening, drove 20 miles on wednesday morning without any CEL but it came back on my way home in the evening...

 

you can always attempt diagnosis using brake cleaner while the car is running. spray anywhere you'd think there to be a leak or missing vacume hose. if the engine idle stutters or changes you've found your leak.

 

check what your LTFT
Most likely a faulty map sensor

 

I'll try that this weekend

LTFT ?

 

Long Term Fuel Trims.

You can check it via a OBD2 reader

 

common for the intake manifold to leak, at the seam so you have to replace the whole manifold. PM me if this is the case.

 

This CEL is a really funny one. One day it is there, the next day it's gone without even erasing the error code.

I tried the test with the break cleaner spray ... no reaction at all.

I will change the MAP sensor just in case, but the light currently gone I won't know if that was the problem

 

He has an 07 E63. While the intake manifold leak is common, the usual fix is replacing the intake manifold gasket, not the entire intake manifold.

 

Light was back and then gone again. Did not come back for the last 500 miles.

I bought the sensor and looked for installing it but still a bit unsure about a few points where I need some help :

1 - What is the black item spotted with the red arrow ? It is filled with a liquid.



2 - To change the sensor I need to remove the metallic part in front of it. I think I know what it is but can't find what it is called in english.



3 - And for that I need to get the tube away. Is that exhaust gaz that go through it or am I mistaken with something else ?



Thanks a lot !

 

that reservoir is your power steering fluid.
don't waste more time on trying to replace random parts to fix an issue like this. first thing is to check the front aluminum bolts that hold down the intake manifold to the cylinder heads. almost guarantee that one of them is loose. if i was just randomly replacing without diagnosing i would remove the intake manifold and replace the gaskets and bolts and also replace the plastic diaphragm/tube thing at the back of the engine.

 

Hi, just read your reply to another member and was wondering if you might have experience with a sl55 I recently had a 0106 absolute manifold preassure code so I changed my MAP, what a pain, code went away for about 4 days and is back, grrr I read that you said the manifold itself can be bad?? Did u mean the gasket? My car has been running rough for quite some time, will drive smooth as glass every once in a while. Any help would be appreciated as this is driving me mad. I also get this strange shudder/light shake at around 1500-2000 rpms almost like misfire or something or like I'm driving on rumble strips but with no actual loss in power. Maybe it's unrelated, recently changed tranny and engine mounts for the shudder issue but no luck, thinking flex disc now , would be great if fixing the p0106 error fixed this issue also, thanks and sorry for the novel....

Best regards,
Adrian

 

Last year the code disappeared ... never came back since then except today. Temperature dropped and reached freezing point (0°c), CEL is back !

 

What Rocman said. Replace intake manifold gaskets and use NEW bolts.
Think there is old TSB about bolts being one-time use.
