Went for a drive, lost power and now car exhaust sounds like it has cams

[jpy1980]

cleared the codes and went for a drive and it still is pretty rough. no lights on the dash but here were my new error codes:

Ok just restarted the car and the SES light came up.

Also was able to run the test that was posted by karter16

I had a similar issue after doing work on some of the relays in the ECU box. I had loosened one of the main ground wires and the VANOS solenoid pack had a floating ground.

See:

https://nam3forum.com/forums/forum/m...os-error-codes

I will also check those as well. I know when the tuning was done for the CSL intake last Thursday, they had to clip into the ECU. I let my buddy borrow my tools so when I get those back tomorrow, open the ECU and find out.

[karter16]

It's not reporting any advance/retard times and looking at the advance/retard degrees it's hardly moving camshafts. I'd be checking the coil pack etc as seems to me from those results like the solenoids aren't actuating.

Would this be a symptom of the Vanos solenoid pack going bad?

[karter16]

Yes although as others have said check the wiring for the pack, make sure it's seated properly, etc. suspicious timing for it to happen directly after people/you have been doing stuff in the engine bay (CSL intake). I would make sure you've checked connections well before throwing parts at it.

Got it. Yea I’m in contact with my installer/tuner. We will see

here’s a video of how it sounds: https://youtube.com/shorts/xEznFrTp0...6VGWCH-5b1Og98

[Slideways]

Did you replace the solenoid pack with the Beisan refurbished one?

[jpy1980]

I don’t believe my solenoid pack was replaced when the work on the Vanos was done. I think the exhaust hub was changed.

maybe it’s time to change out the solenoid pack.

[juju396]

I would verify that the oil pump disc was modified / tabs are intact, as well as solenoid harness connection; but sounds like your solenoid coil pack is failing. I hope whoever did your vanos refresh also replaced the solenoid sealing plate rings from original buna to viton rings. Here's additional info:

https://beisansystems.com/s54-vanos-solenoid-procedure-e46-m3/

"Symptoms

Fault codes:

P0010 (BMW xx, 0xxx): Vanos intake solenoid circuit
P0011 (BMW 67, 0x43): Vanos intake timing over advanced
P0012 (BMW 72, 0x48): Vanos intake timing over retarded
Pxxxx (BMW 184, 0xB8): Vanos intake position control
P1525 (BMW xx, 0xxx): Vanos intake solenoid open circuit

P0013 (BMW xx, 0xxx): Vanos exhaust solenoid circuit
P0014 (BMW 22, 0x16): Vanos exhaust timing over advanced
P0015 (BMW 21, 015): Vanos exhaust timing over retarded
Pxxxx (BMW 185, 0xB9): Vanos exhaust position control
P1531 (BMW xx, 0xxx): Vanos exhaust solenoid open circuit

The failure of the vanos solenoid will cause the DME to not utilize the vanos. Unfortunately the engine timing is left in the same position as when the failure occurred. Thus the engine will likely behave better at low RPM and worse at high RPM, or worse at low RPM and better at high RPM. Engine misfire with fault codes can also occur.

Diagnosis

If a circuit code is present, disconnect the vanos solenoid electrical connector and spray clean both connectors with electronic contact cleaner. If this doesn’t resolve the code then the solenoid coil pack is likely failed.

A relatively less common failure that causes the above codes, less the electrical codes, is sticking solenoid valves. The solenoid valves can be cleaned as outlined in the procedure to address this possibility.

The above codes, less the electrical codes, can also occur when the vanos oil pump driver tabs break. Thus an effort must be taken to distinguish between the vanos solenoid coil pack failure and the oil pump driver tab(s) breakage.

A simple, but not conclusive, method of differentiating between the two failures is to reset the fault codes and start the engine and allow it to idle. If the oil pump driver tabs are broken the fault codes and check engine light will be generated in a few minutes. The solenoid coil pack failure is often intermittent and will take some driving before the fault codes and check engine light appear.
Unfortunately, there are cases where the solenoid coil pack can be significantly failed and the fault codes and check engine light appear at idle after reset. Further in some cases only one of the oil pump driver tabs will break. In such a case the fault codes and check engine light will not appear at idle and some driving will be necessary for them to appear.

A definitive method of assessing which of the two failures exists is to remove the valve cover and inspect the oil pump driver tabs. If one or both are broken then that is the source of the problem. If they are present then the problem is most likely the solenoid coil pack."

Thanks for all the info guys.

I ended up ordering the solenoid pack so i’ll try and replace it when I get it to see if it solves the issue.

I want to try and fix it at home prior to me having to get it towed to my mechanic who is about 31 miles away :/

Yea I read all of that. I just ordered the solenoid pack so hopefully that fixes it. If not, it’s off to the shop.

This happened to me twice - the first after an oil change. The solution? Cleared the codes and the misfires went away.

~3,000 miles later and after another oil change, misfires again. This time I pulled each coil while the car idled and identified a dead coil pack. Replaced all six and the misfires went away.

OPs VANOS test is failing - the engine is unable to advance and retard the cams - it is a different issue.

[Stilt]

I don't believe my solenoid pack was replaced when the work on the Vanos was done. I think the exhaust hub was changed.

maybe it's time to change out the solenoid pack.

I'm not sure if this has been aforementioned already but, does the car feel like it has no high end power / in the higher rpm's do you not notice an audible change in the exhaust tone?

If you do, then it is the vanos seals 100% - which happened to me.

Seals = pressure, no pressure = vanos no worky.

I had misfire codes on all cylinders once and I completely forgot what the issue was, whoops.

I think the misfire codes was from when I had to replace the solenoid pack.
