1. Year of Car: 2004
2. Current Mileage: 43,800
3. Euro? U.S.? Canada?: USA
4. Mileage at failure or discovery: 42,772
5. Actual failure type: Actuator and/or camshaft position sensor. I replaced both and the problem was fixed
6. Symptoms of your VANOS issue (idle, roughness, noises, power loss etc…?): Nothing perceptible. Just SES light.
7. How did you determine what parts or parts failed? I researched the problem here, spoke to Dr. Vanos, and PMed members with similar problems and determined it was likely the solenoid. Unfortunately, a new solenoid did not fix my problem so I narrowed it down to the actuator or camshaft position sensor.
8. Did you have dash warning lights show up?: Yes, SES
9. What fault codes if any showed up?: Peake: B9 - Exhaust camshaft VANOS position control; GT1: 185 Function, exhaust VANOS
10. Who fixed your VANOS issue?: Indy Shop
11. Cost to repair (details please): Parts: Dr. Vanos rebuilt VANOS actuator (~$400 net of core exhange), exhaust camshaft sensor (~$80), numerous gaskets (~$100); Labor: 4 hrs. at $90/hr.
12. Track use? (none, a little, some, often): None to my knowledge, but I'm the 3rd owner
13. Original owner?: No, 3rd
14. Changed oil at what interval: About every 8,000/mi.
15. Other comments or history of car: My VANOS problems arose after about one month and a couple hundred miles of ownership. I suspect that the previous owner knew about it and hid the problem by resetting the SES light!

I was hoping this was a 03.5 and up issue. I'm amazed that there isn't a recall issued yet for the vanos bolts.

Noticed same thing, being a 2001 owner with crossed fingers. Was there a running change from 2002-on or just chance that no 2001s have fragged their motors and owner's wallets?
