The camshaft sensor isnt the camshaft solenoid sensor right? and if not where is the camshaft sensor located on a bmw 116i f21? i cant find anything online, unless its the solenoid @Johnnyroper

Hi, thanks both for the reply.

i cleaned those sensors and still have the drivetrain issue.

Its so weird because if i let the car sit there for 5 - 8 minutes its fine.. then the drive train issue comes and an engine warning light comes... then 2 minutes late engine warning light is gone but drivetrain malfunction is showing and the car still sounds rough and is in limp mode?

As soon as i turn the car off and on the engine light is gone and so is the drive train malfunction.

i can only run the obd scanner when the engines on as thats when the warning light comes with the code..

Im completely stuck now. Ive ordered a more expensive obd scanner in hopes it reads / displays a more indepth error..

 

[lowaaa]

Scanner came and this is all it says... @Atyn or @Johnnyroper

So I presume this obd scanners as useless as the other but with a higher price tag.

One thing did notice was the Catyalyst temperature bank 1, sensor 1 was returning 315.32 degree F

Fuel rail pressure at 1001.95 psi with a fue lelvel input of 34.118%

and engine coolant temperature at 145.4 degree F.

The water pump rubber does look quite worn so could it be that? Although not sure how it would effect the camshaft..

Starting the car up once more brought a new error, that being P1339. Are P13c0 and P1339 in any way related?

 

[lowaaa]

thanks for the link @Atyn I checked my ecu for the ecu variant, but no clue on which one it could be... The label on the ecu says DME but not sure if that related to any of the ecu variants that website shows..

I'm assuming it's got something to do with the alignment of the timing chain after reading the fault info on that website.

 

[lowaaa]

Thanks for the links @Atyn I'll order the cam sensors as the 'fault info' suggests doing so. Regarding the solenoid, the car came with it damaged. (literally looked like they tried hammering it out. I ending up getting it out and putting a new one in and it slid in perfectly fine, so that's already new.. however the harness has seen better days and I may need a new plug. But again not sure how much of an impact that could be especially if it still plugs in.

The oil and filter were changed a few days ago. From what I read the oil amount was from 4.2l to 4.7l

wait wait.. theres TWO intake solenoids?! do you possibly have a diagram of where the exhaust one could be found?

Now noting that the intake solenoid (under the ecu) had been replaced with a new one, could it merely be the exhaust solenoid causing the issue or would it not work like that?

BMW Fault Code Lookup - BMWFaultCodes

Look them up. But 1339 relates to exhaust camshaft so looks like your issues are all related to the vanos.
Could be a faulty sensor.

Cam sensors are about £14ea from Autodoc so not too costly if they didn't cure the problem.

Enter your reg no. to find the correct part.

P13C0 is intake vanos and the above site suggests intake solenoid but click on 'view' for more into. Note the comment about oil pressure - when was the oil and filter changed?
Might be worth using some engine flush if they need doing.

The intake solenoid is on the drivers side at the front under the ecu but fortunately more accessible than the exhaust one on the opposite side.

The solenoids are £36.

I found an image on a pdf of it. I think this is the one the previous owner had problems with but had no idea where it was. It was difficult finding the the image for it's location and after seeing what job they did on the previous, i'm sure they had no idea where this one was.

So i'll order another solenoid, the two sensors and I'll see how it goes. I've also ordered a new obd scanner, one which can work with bimmerlink in order for me to find the specific code. I'm just hoping its got nothing to do with the camshaft timing as i have no clue on how I would even begin a job like that.

 

[lowaaa]

Ive scanned the car with bimmrlink and saw a few errors. In regards to the camshaft ive found this and based on 130F20, i think its needs either a new timing chain or realignment :/ @Johnnyroper @Atyn

 

[lowaaa]

@Johnnyroper @Atyn could either of you refer a link to a set of tools for the locking of the camshafts please?

 

[lowaaa]

@Atyn yeah i got the chain kit, but there were several timing chain locks. thank you for the link, hopefully this goes well.

to confirm, only need the timing chain kit and the locking kit and nothing else right

 

[lowaaa]

thank you

 

[lowaaa]

@Atyn or @Johnnyroper or anyone do you know of any videos / pdfs of how to align the camshaft/ where the camshaft marks are? ive only found videos of people removing the chain but not really aligning it?

thanks

 

[lowaaa]

ive bought that, i have it now but and sorry if this may be a silly question, i understand it locks the camshaft in place, but the camshaft can be mis aligned right? so how does it align both the intake and camshaft to be in the right position if its out of time / alignment?

from what i understand 'Angular offset to crankshaft outside tolerance' means its out of alignment right? dont i need to align it when replacing the chain and camshaft/intake? @Johnnyroper


thanks

 

[lowaaa]

Ok, cam lobes pointing up. The kit i bought includes intake and exhaust gears (the two gears that the chain goes on) when i take them off to replace, do i put them in the same position they were in or does it not matter as ive locked the camshaft as well as have the cam lobes pointing up? @Johnnyroper

thank you again )

 

[lowaaa]

Hi @Johnnyroper , ive taken off the cover and attempting to lock the camshaft in place but it seems one is out of timing. I read your.message about slacken the cam bolt but is that the bolt.which is holding the intake/exhaust gear in place? and when i loosen it all i have to do is turn the engine?

also is my engine at tdc?

 

[lowaaa]

@Johnnyroper @Atyn

TL;DR

original error gone, new one intake camshaft stuck, when maf sensor unplugged, camshaft error codes gone and car drives with no drivetrain issue.


LONG INFORMATION BELOW

=======
so i realigned the chain instead of changing it. I know i should have changed it then and there but i saw that it was mis-aligned and thought let me see if its actually just the issue that its not aligned.

so i aligned it and guess what, error gone regarding the 'Angular offset to crankshaft outside tolerence'.

However, drive train came on after 8mins and i checked the code and now its error code 130104 intake control error camshaft stuck.

I have both new vanos sensors, and the two camshaft sensors. all new. It being stuck could of caused the misalignment originally and the two gears need changing.

I also changed the plug for the vanos intake as that was broken. However, i forgot to put the air filter box back together (including maf/air sensor on the turbo tube connected to the air filter) but i didnt know until 15mins later checking the engine, but for 15mins the car had NO issues. Nothing. no drivetrain malfunction, no engine light, nothing.

I put the air filter back on and plug the maf sensor and guess what... drive train issue and the intake camshaft stuck. When i remove the maf and the air filterbox, only issue is air mass meter signal 102A01,

i even drove the car around and saw no loss in performance (under 30mph). i did hear a ticking noise but that could be because i only filled up 3.8l of oil.

My plans are to check if the alignment moved tomorrow morning and if it did im changing the timing chain. Regardless of what i do, ill changing the chain. my question is, could the maf sensor override the camshaft sensor or could it be the maf sensor is messing with the camshaft sensor and causing it to error code?

just checked that error in bmwfault.code and it seems that the oil being low could be the issue as i know i only filled in less than 4l. But why does the issue go if maf sensor is missing ????

 

[lowaaa]

Yeah ill be changing it tomorrow, i was just checking the issue

 

[lowaaa]

@Atyn @Johnnyroper Changed the timing chain and the intake and exhaust and its somehow worse now. Now the drivetrain issue happens immediately and the car sounds like its choking. Too much oil maybe?

I get this error code 130108 and have no clue on what that even means. ive read the the bmwfault.codes and nothing. Im now leaning towards a turbo failure because of how the engine is choking.

any clue ?
