Need help doing vanos test with INPA

[sapote]

though there is not a wall on the inward motion of the spline, there is a hard stop, and that is the slot on the cam sprockets, that is the physical limit, and if the timing was off a bit 59 was as much as it could get.

Max retarded position is limited by the vanos front covers, and the max advanced position (piston moved rearward) has more margin beyond the operating advanced timing and so this end should have no problem of achieving desired angle = actual angle.

59 is the Intake actual retarded (limited by vanos cover) and not when the spline bottomed out on the cam sleeve or the cam shaft.

I think you are just jumping to answer, read what I said. anti-clockwise motion is capped by the caps (pun intended), clockwise motion is limited by the slots in the sprockets. that's it. the cams will get anywhere between those hard points.

Sorry, but we're talking the timing value during engine running and not during a vanos timing set. The slots in the sprocket are only involved during timing setting and they are useless during dynamic timing change with engine running. As soon as the hub bolted were torqued down, the slots are out of the operation so why they are in the discussion of the advanced angles?

Thank you so much for the 1 click test solution using Tool32. Was very excited to be able to run a vanos test on my system as a base line before i do a vanos refresh. One thing i'm confused on is why my log file appears to be shorter than some others that have multiple pages. i did a select all or ctrl A in the log area and grabbed the text but my log file i saved in TXT format doesnt have any other sections after:

apiJob("mss54ds0","STEUERN_AVANOS1_DICHTHEIT",""," ")

can someone look at mine and let me know if the values are in spec? Or will i need to rerun the test to get more of the log file that i might be missing?

Seems OK to me. All jobs were performed that are listed. 1. retard endstop 2. Advance endstop 3. Activation speeds & 4. leakage test for both sides (8 in total)

Intake is perfect, the position were 0-60°CR (0-60°CR necessary)
Exhasut same, 0-48°CR (0-45°CR necessary)
Intake speed very good 195-205ms (BMW says that anything below 500ms is good, I would rather take 250ms)
Exhasut speed 152-193ms. Exhaust has less degrees to travel (45 vs 60 on intake) I suspect its fast due to this. Numbers looking perfect.
Both intake and exhaust position are drifted. I am not sure how I would need to understand this. I wouldn't worry about it.
So no issues and good results.

thanks so much man.

just curious why my log appears to be smaller or missing information compared to this other persons in this post

they seem to have more data? did they run the test differently or did i miss any of the logs somewhere?

[Tomba]

The "dichtheid" / leak test performs OK on these and comes with more data. Still similar jobs being performed

Hi - Thank you Tomba for putting this together. I recently rebuilt my Vanos with Beisan seals, etc. and wanted to test it out. Not having access to Autologic, this was great. Question: For the 'drift' test, what is the expected result? I do not see any test results showing other than "AVANOS-1-Einheit vorzeitig weggedriftet".

Below are my results: 61 for intake and 47 for exhaust. I also noticed that if ran the test a few more times, the activation speeds seem to improve, but these are the initial results.

For the 'drift' test, what is the expected result? I do not see any test results showing other than "AVANOS-1-Einheit vorzeitig weggedriftet".

No or small drift. My suspicion is,
- camshaft is set at a position
- none of the electric valves are activated for xx seconds
- after xx seconds the position at the beginning and end is checked against each other
- If too large difference is observed you will see an error

But I am not 100% sure.

so, my vanos its ok?

Your adjustment range is perfect.
0 to 60 for intake and 0 to 48 for exhaust is the spec.

Your adjustment times are within BMW spec, but a bit slow in my opinion, mine does intake in 200-230ms and exhaust in 180-200ms, so there is some improvement possible there.

Generally we declared under 250ms to be good, iirc.

Hope this helps.

So, do you know what could be causing this slowness?

[eacmen]

Thank you!


So, do you know what could be causing this slowness?

Oil pressure.

Solenoids.

[Pklauser]

Oil pressure.

Solenoids.

Specifically VANOS oil pressure. You may want to get a gauge together and measure. There are some good threads around here on it.
