I’m just here to join the party of people with timing issues 😭 I set the timing flawlessly IMO using the Amazon special camshaft locking timing tool kit. I will go to the euro shop a few towns over from me and compare my kit to his oem kit and see if there’s any difference in specs.
Are you guys checking the exhaust and intake spreads? I’m using BimmerLink to log mine. Intake camshaft spread should be 120 and exhaust camshaft spread should be 115. My camshaft spreads are spot on +-1 degree, for about 5 seconds. Then my intake side increases to 137.9 and stays stuck at that exact number until I reset adaptations. With this code 130104 VANOS intake: control fault, camshaft stuck I replaced both cam sensors, swapped all the sensors back and forth, swapped the solenoids back and forth. Nothing changes |

When I unplug the harness from both vanos solenoids, the car runs and the sensors detect a nearly perfect 115 exhaust and 120 intake spread. It seems like the solenoids plugged in just pump the valves with oil and throw the timing off? Maybe the dme needs full software update to the latest I-level? I think I’ll try that next I’ve heard of that fixing the issue for other people after doing timing.

Let us know if there is any difference between the tools. I think it’s possibly the vanos unit itself that is at fault.

I did compare the tool to the shops tool and they claim they have successfully timed n55s using their tool. They looked the same by eye. Maybe it was a bit silly to not bring my micrometer with me but yeah the seemed to be the exact same

I could be wrong but my motor seems timed right. I’m just having a vanos intake camshaft stuck code. Wish I could help more. |

Thanks for checking. I don’t want to pull the bearing caps either, that’s a new head!! I may try putting the crank locking tool in and rotating the engine counter clockwise against it. I just can’t come up with anything else.

attach a dial indicator to the top of the timing kit and reach it over to piston #1 and run some sort of 1/4-3/8" extension through the spark plug hole to confirm your at true top dead center on piston #1.
takes some rigging/creativity but thats what i had to do because i dont have a TDC hole on my aftermarket flywheel (6mt) |

My kit came with a gold coloured bar across the top that says for N55 engine. Slightly shorter than the black one that it came assembled with.

Success. Used a dial indicator to ensure TDC. Put on the original exhaust Vanos sprocket. Hard to see a difference but I biased any tolerances to the advanced side. Vanos is happy, valvtronic is operating and turbo is back on. !
Thanks everyone who chimed in with advice and encouragement. |

Good job buddy!! I wish I could figure mine out I believe my problem is due to wear on the cam / camshaft caps

Hi, guys!! Thank God I figured out my problem aswell, just didn’t post anything till today. It ended up being my intake vanos plate for the camshaft position sensor that was off a tiny bit. That’s why the computer thought the timing was off when it was not. The red tool in the picture above went into the holes of the plates and was able to be screwed onto the engine, but it was at a tiny slant which cause the plates to be offset outside their tolerance range.

I do have a new exhaust vanos if anyone could use it, let me know.

I'm 'finishing up' an f10 project. Long story short, I got it dirt cheap, it had sucked a belt, I cleaned all traces including oil pickup, etc (I have done this job several times), new valve cover, fixed all oil leaks. Unfortunately I am getting Vanos codes on the EXHAUST side (code 0304 exhaust camshaft stuck and once in a while the cold start counterpart). I cleaned and swapped solenoids and also operated them while cleaning with a 9v. Even swapping them it is the exhaust code. Engine purrs like a kitten... but it is in limp mode after short drives. While running at idle, ISTA says 10.5 degrees for exhaust and 8 degrees for intake (both are approximations). Is that high? I can't seem to find the 'normal' degrees with my Google fu. If those ARE high, that makes me think the belt wrap threw timing off just enough to screw things up. If those degrees can be considered 'normal' my next thought is to try an adaptations reset and perhaps update the software. Then I guess I am opening of the valve cover again... |

Also, can you clarify what you mean when you say you biased tolerances to the advanced side? I’ve timed n52s, n54s, and an n20, but after this thread I’m concerned the n55 may be difficult to time properly! I haven’t touched timing on this n55 yet but plan to check it as process of elimination since solenoids did not fix my “stuck exhaust cam”. |

The timing kit was fine to use. I did use a dial gauge to find tdc. What i mean by biasing is there is always a bit of play when you put the pin in and the cam lock. I rotated the cam a little past centre and then brought it back so the cam lock was tight on one side. I did not change my chain.
