so what do ya think?
Yes, it is totally possible for a sensor to fail with out oil contamination.
is there a possibilty that it is the valvetronic motor itself?
I wouldn't expect you'll have to change the valve cover in the process but refreshing the gasket is always a good idea.
i just dont want to rip this whole thing apart and not fix the prob
right...i do have a new gasket
Hold tight for a few minutes and I'll be in front of my books and can give you the whole process!
i have a DIY im using from bimnmerpost too
Ok, so here's what my shop manual is telling me:
Remove the microfilter housings and coil cover. Rotate the motor in a clockwise direction gently until you feel resistance on the eccentric shaft stop. Remove fasteners and pull motor out
It sounds like you're already there so at that point installation is the reverse of removal!
Pulling the valve cover should not be needed although if you have the gasket I might change it for the heck of it just so you know it's fresh.
i dont have a new motor...i have a new sensor
Haha, ok, on sec
the valve cover have to come off to get to the sensor
i was just wondering if it is possible for the motor to be bad...and not the sensor...and if there is any way to tell
bc the sensor does not have oil in it...which is typical i guess for a bad sensor
but you are saying that the motor is much easier to replace than the sensot
It is, looks like about a 20 minute job with the right tools.
What led you to replace the sensor?
Can you post a link to the DIY if you don't mind?
bc when i read the obd2 code it said P1017
which is a faulty valvetronic sensor i guess
That's a pretty comprehensive overview, nice!
Before you get too far into everything I'd see if you can find someone with a BMW scan tool
and perhaps there's another code that would be more clear.
unfortunately i dont know anyone with that tool
Let me look up that code though...
Ok, that's definitely the sensor code. Did it come back immediately after clearing it?
came right back
also...the spark plug things with the little flip up lock things...do i just yank those out?
Yes, carefully! :-) They should just pull straight out.
there was 2 codes...duplicatea
Before you get too involved, can you clear them again and go for a test drive?
ummm....its too apart for that, lol
she has been driving it all week after i cleared codes
Happens not at any certain speed, begins to chug and the yellow check engine light comes on. Chugging stops and then awhile later while still driving it goes off. Doesn't happen everyday
The other day after sitting at airport for 2 days in the structure it took 3 tries to start but has not happened since when in my garage
Yeah, classic sensor failure symptoms, sorry to say!
alrighty! well i have that part...now just gotta do the work, lol
will u be around later if we need help again? haha
Yes, I should be! I'll be at the shop for awhile and after that I'll get emails if you ask me more questions. Good luck!
ok thanks! ill leave this window open
Perfect, same here.
sooooo.....i got everything off.....but when i took the bottom bolt of the sensor.....it felt down into the chain housing area. i tried sticking a magnet down there but i didnt pick anything up ....can i remove the oil pan to get to it? its an XI so does that mean there is transfer care and junk underneath the motor? uhggg.
Sorry I'm just getting back to you now, I've been working!
Are the other bolts aluminum?
They are not aluminum so if we can locate it we should be able to pick up with magnet. Problem is locating it! Trying again this morning in daylight but wondering if a different perspective from underneath will assist. To question above can we remove the oil pan and get to it in your opinion? It's an xi....
I would avoid it if possible
because the front diff and axles would have to come out I believe
but as a worst case, don't discount it...
Don't worry, I have been EXACTLY where you are more than once!
Get a really big flashlight and use your magnet
Failing that, I'd drain the oil and try to fish in through the plug hole first. If you get nothing there I might try to pull the Thermal Oil Level Sensor and see if you can get in that way.
I wish you the best of luck, let me know if you find it!
where is the thermal oil sensor?
It should be on the bottom of the pan, probably on the drivers side
we r goin to go buy a scope
and a snakey magnjet
it might not be there on your car, but if it is you you'll see something held in with three 10mm nuts
Good! A scope and snakey magnet are my best friends sometimes...
No problem! Good luck!
Keep me posted!
well...went and bought some better stuff...but still cant find it from the top
scope really cant see much....not enough light....i havent tried the oil pan thing, but my neighbor seems reluctant to try that....bc we have to drain the oil.
i mean if we cant see it at all from the top and havent picked it up with the magnet...then i think theres really only one place it could be
Well you're going to have to drain the oil no matter if you look in through the drain plug hole or drop the pan...
i can go thru the drain hole with the scope.
we just dont know if its worth it
cause if we do all that....and its not there
Then you may have to start dropping the pan
You might be able to drop it a little ways and reach in with the magnet
or see in with the scope
what's the last seven digits of your VIN?
I'll see if I can find a diagram
ok, let me get it
Ok, one minue...
That's a diagram of your oil pan if that helps at all...
I'm guessing the bolt would have to be in front part
ok....so in all likely hood it would be in front which is the deepest part
So I'm not sure if the drain plug will help you in this case
but the good news is it doesn't look like it's dropped any further back
well...it would be enough to get the scope in there
Like it did on the LAST car I had this happen on...
Yes, getting the scope in would be a big help
On the S52 motor on the E36 M3 the deepest part of the pan is midway back
I had a bolt fall in one of those once
Just trying to give you some words of encouragement!
i just hope its not like in a chain valley or tensioner....thats my biggest concern
if its in the pan...then thats fine
i tried to stick the magnet in all the places i think it might be on top of the motor
Did you hear it fall?
i did hear it
the classic tink tink tink, lol
and did it sound like it dropped all the way down
and maybe splashed?
lol, no splash
I'm not sure it would have made a splash in the oil anyway but perhaps it's not all the way in the pan...?
theres no telling where it is really
I'm thinking it has to be in that right side chain guide somewhere...
the right side....hmm
Of the picture
I guess left side of the car...
theres some space behind the left hand guide as well
and it might be there
i dont know....im very aggrivated
I don't blame you!
u think i should just give up and have it towed to an indy shop or something
I'm sorry you're going through this, I've been there, it's not fun!
would they have better methods
yeah....this really sucks, lol
Maybe drain the oil and try looking in the drain hole
so if i was to do this....how do u get the car in neutral without starting the car
if that fails, have it hauled off before you try setting anything on fire!
I believe there's a procedure in your manual
but I'll look it up anyway
you have to pull up the shift boot and do something with a screwdriver
I've done it, but it's not fresh in my memory
its an automatic
one second, I'll look it up
and also...should i finish the job up top...and then have it taken away....or just leave it taken apart
That's up to you. Keep in mind you're missing a bolt though so don't get it too buttoned up!
Oops, let me make that a link
That's the neutral override I was referring to
couldnt i just go get a bolt from ace hardware?
If they have one, sure. Was it a Torx head though?
nope...just a 10mm head
short tho...and not threaded all the way up
Ok, well that's easy enough
you just need the right length
are they gunna want to pull it all apart again to look for the bolt, or is it easier for them to go from= the bottom?
this is the last question i promise, and im gunna give u the best rating, lol
Lol, no sweat!
I'm not sure what they'll want to do
It might be best to leave the top loose so they can look in there
maybe just place the cover on top but don't bolt it down?
well...we r going to decide what to do.
Ok, good luck my friend!
No sweat! Where are you located?
lake orion, mi
Ah damn. Sadly I don't know any shops in your area
