Need help doing vanos test with INPA

[BMWfanz]

Check vanos connector and wiring on solenoid pack

[JP1580]

I'll check again today but it seems that it works half the time.
Last time I changed the Vanos block, I ensured to hear the "click" and I zip tied the connection.

The P0014 code appears to be a VANOS timing issue. I recently the VANOS test while the car was running, and I have attached the results (jpeg) to this post.

the attached file lists the inpa error codes, but nothing about the vanos test result.

P0014: the EX cam timing is too advance. You need to check and set it to the correct position.

[JP1580]

So yes the attached file is the new CEL codes post Vanos test.
I posted the VANOS test results as a jpeg.

Side note:
Confirmed that the plug is fully seated.
Started the car last night for 5 min.
Ran great no CEL.

I have a refurbished solenoid pack from Beisan that I'll install Friday.
I'll report back with results.

I can't find the file.

Does this works?

Looks like intake cam vanos is not working at all. Any codes?

[JP1580]

To me, it looks like everything is pointing to a bad solenoid pack * Intake Camshaft is Stuck in Retard
* The intake camshaft did not move at all when requested. It physically remained parked at the retard stop throughout the entire 5ms test window.
Most Likely Cause: solenoid pack

It ran great last night for the 5 min it was running.
I have a refurbished solenoid coil pack that came in a day or two ago. Plan is to install it and re-run the test.

I know it says that the Vanos test should be ran at warm temp but if the soldering pins are making contact at cold.
Can I run the tedt at cold (say after 5 min from startup) to confirm my suspicions?

Car is throws P0011 and P0014 after driving moderately hard.

Have you retimed engine after vanos rebuild?

[JP1580]

I bought the car for a friend. He confirmed that the engine was retimed after Vanos rebuilt (the body and pack were not changed during rebuild)

Car ran problem free for 3 years since rebuild. Occasional CEL for old gas (coming out of storage) since he barely drove it. Ran beautifully after a fresh tank for the season.

These CELs are 3 months old

Does this works?

The test wasn't set up correct.
For Intake the top 2 command should be like these:
EVAN_SOL -10 (but your shows 52); the dme commands the intake to move to -10 deg but your test commands to move to 52. Double check if the right engine is selected.
EVAN_SOL 75 (but your shows 52); the dme commands to move intake to retard 75.

The same for exhaust, should be
AVAN_SOL -10 (your shows 20)
AVAN_SOL 55 (your shows 20)

You didn't use the software tool correctly.

When I start MEDIA AS Toolset 32
- Under the ECU library, I select mss54ds0

I feel I may be doing something wrong.

I swapped the solenoid coil pack.
P0011 is gone.
P0014 is pending.

The car is still showing a misfire on all 6. I'm lost now.
I have the valve block and solenoid changed.

Could it be some trapped air?
It's almost 11PM. I'm not going to take the car out

Looking for someone to walk me thru the steps.
I checked YouTube university and fell short.

Update:
Ran individual solenoid actuation tests via Tool32 using MSS54DS0.PRG to rule out electrical failure in the VANOS solenoid valve block (coils, circuit board traces, connector pins, and DME drivers). I DID ask ChatGPT.
Procedure:
With key in Position 2 (ignition ON, engine OFF), I executed the following individual valve actuation jobs in Tool32:
steuern_evanos1_frueh_ventil (Intake Advance Solenoid)
steuern_evanos1_spaet_ventil (Intake Retard Solenoid)
steuern_avanos1_frueh_ventil (Exhaust Advance Solenoid)
steuern_avanos1_spaet_ventil (Exhaust Retard Solenoid)

Results:
All four jobs returned JOB_STATUS = OKAY.
Distinct, audible metallic clicks were verified directly at the solenoid pack for all four tests.

Conclusion:
The solenoid pack is electrically fully operational, ruling out dead solenoid coils, cracked circuit board solder joints, connector pin corrosion, or DME output driver issues.

Next steps is to pull out the VANOS assembly and confirm tabs are not broken. That's the only thing I can think of as to why it's not building pressure.

Oil level is showing full.

1. solenoids are clicking under test, so they got elect current ok, but nothing to tell if the solenoid valves are working properly.This is why using Tool32 to move the cams is the proof.
2. how do you know vanos pressure not built up? Must install a P gauge on the vanos banjo bolt to verify.

Heads up:
Just realized that there's a new file for the test (under page 6). It adds leakage.
I was using the file from page 1.
I'll run the new test.

Anyone know where to find a manual or video(s) on how to use tool32?
