Need Known Good CMP/CKP Waveform
Code came after Timing Cain replacement. Job was done with special Holding Tools. ReChecked 3 times. Has OE new oil control solenoid for Exhaust cam & CMP sensor. Red- Cam2 Green Cam1 Blue- CKP
ill set a reminder, we have 5 of those M54 X5s outside.
Thank you Diego. I'll be looking forward to that chart. M54 seems to be a hard one to find. Happy Holiday
this is cranking capture, ignition disabled. Based on your pattern I kinda suspect you may have an oil pressure loss in the vanos system. I would advise to do the air check the vanos unit and look for movement and listen for massive air loss. Air checking requires the fitting from your tool set to tap into the oil supply line and using something to activate the solenoid (switch or power probe)…
Thank you Justin. We'll work on the testing I'll have an update next week. Happy Holiday
Just small tip to add to Justin's post, when checking the system with air at the oil feed port, yes there is a fitting, but you can also do what I was shown at the dealer if the fitting wasn't around, you can take an old used vanos line and cut it to where you can still bolt it in with the banjo to the vanos but the other end is open port where the rubber hose gets cut and you can feed air that…
Justin, the images are from a running engine. I forgot to attach #1 cyl. marker.
I performed a Vanos air test. It seems to be working properly. The images I attached were from a running engine. If someone can supply me with a known good image I'll perform the running test again this time with a number 1 cyl. marker. The data is showing a 5.9° adaptation this is an alignment issue I believe.
