@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

 

[Johnnyroper]

Rocker cover gasket aswell, sump gasket if you are taking sump off to check for debris which is advisable. Obviously oil and filter then aswell

thank you

@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

 

[Johnnyroper]

There’s no marks you need a timing kit like this to align and lock the camshafts and sensor pick up wheels

 

[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

 

[Johnnyroper]

You need to lock crank shaft at TDC with the locking pin, make sure cams are in a position where number 1 valves are fully closed the cam lobes should be facing upwards but not completely vertical.
As it’s a 4 stroke you can have camshafts 180 degrees out so you need to confirm lobes pointing up.
If the locking tool won’t go on as cams slightly out of time then you will need to slacken cam bolts and move camshafts with a spanner until tool will slide over and lock them up.

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 )

 

[Johnnyroper]

The vanos hubs can go in any orientation, you just need to make sure you match inlet to inlet and exhaust to exhaust. The bit that needs to go in correctly is the cam sensor pick up, there should be a lock tool in kit to align them.

 

[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?

 

[Johnnyroper]

No don’t turn the engine, when crank is locked slacken the sprocket bolt and then use a spanner on camshaft to rotate back in to time and fit cam lock.

@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 ????

 

[Johnnyroper]

If timing was out then something has caused it, putting back in time has not resolved that.
Until you resolve the timing issue which is most likely stretched chain and breaking up guides it’s pointless changing anything else.
You need to replace chain kit and check oil pick up for debris, as that will have same weren’t on oil as having not enough in it

 

[Atyn]

I saw a comparison of a N13 chain - original and new one on YT. There was a big difference - looked about 10mm.

Definitely a mistake not to change the chain and guides. Don't be surprised if the codes return.

 

[Johnnyroper]

I changed an n43 a few weeks back and that was probably 10mm difference. Original one the tensioner was at max extension but chain still had slack in it

 

[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 ?

 

[lowaaa]

apparently i need to reset the vanos.adaptions using ista +? can i use ista + with a Bluetooth obd?

 

[lowaaa]

any idea anyone on what 130108 could be related to? Checked the bmwfault.code and Ive already changed the sensors and the checked the oil or @Atyn @Johnnyroper any clue / have you experienced this before?

 

[Johnnyroper]

Ista needs icom or enet calve for f series cars or k-dcan to usb for e series cars.
I would check vanos operation with ista could be hub issue or the solenoid, have you checked the screen around solenoid as they can get dirty. Also have you checked the oil pick up pipe for blockages as that can also cause oil problems so will have an effect on vanos.
What make sensors did you fit?
