Do you also have any engine performance issues or just the code is present?

Customer reply replied 2 months ago
The code is present. I was told two different codes at two different times. Now the light went off by itself.
Customer reply replied 2 months ago
The car drives the same.
BMW Mechanic: Gunvir Singh,
 replied 2 months ago

Both the codes 2A87 and p0015 are same codes, depending if you use generaic or vehicle specific sensor to read it. Since there is no performace issue, i wil recommend to check the engine oil/filter level and quality as VANOS works with engine oil pressure. If good, The problem could be a failing VANOS solenoid

How much would it cost to replace VANOS solenoid?
Customer reply replied 2 months ago
The dealer recommend Exhaust Vanos Camshaft Unit, which will cost $1400 or $2200 with exhaust bearing ledge
BMW Mechanic: Gunvir Singh,
 replied 2 months ago

If it is just the VANOS solenoid, it should cost approx 250$. I doubt the vanos camshaft unit needs replaced as it is not gining any performance issue.
