Greatdane, I have never done plugs before in my life or Vanos Solenoids.
I just did them on Saturday, my plugs and Vanos Solenoids.
Scale of 1-10.
I give it a 3, max 4.
I used the follow videos on you tube.
Look them up:
AskCOBB Episode 2 - BMW Misfire Diagnosis and Repair
And
BMW Vanos Solenoid Replacement Intake and Exhaust N51, N52, N52K, N54 Faults 2A87 2A82 2A9A 2A98
My notes:
For the vanos, take the cover off only helps and just gets it out if the way.
When pushing the new Solenoids in, requires more force to sit flush.
The new o ring on the solenoid, I just used some of my engine oil to lubricate it.
Put a towel under the solenoid before removing to prevent oil from landing on the belts and what not.
Engine must be cold, like over night.
When you lose the solenoid bolts, then use your hands so there is no chance of the falling.
If you have the proper tools.
Should take you 10 min to get the cover off, if that.
I got the Solenoids from BMW dealer on eBay.
I even called them to verify that they were new and oem, factory sealed.
Hope this helps.
