XZBMW  Bmw E87 116I N43B16 2A87 code
Have a 116I E87 with the N43B16 engine, have done the timing chain and changed the Vanos solenoid aswell as oilpump and oil pressure valve.

Keep getting the 2A87 Vanos code, also the car would start and shut off after a few seconds, if i disconnect the Exhaust Vanos electrical connection the engine starts and runs.

Anyone had this issue before or know what to do? i have also checked the oil filter cage and the tap with O-rings that goes into the bottom, but looks good.

Why are you not suspecting the vanos gear? When you go to ECU functions, vanos gear do you see movement of the gear? Are you sure inlet and exhaust connectors not reversed?

Hehe, i was very cautions then putting everything togheter that i should put the vanos unit in the correct place, i even put each unit in a bag and marked them, aparently what i did was somewhere along to mix them up.

So, new stretch bolts ordered and ready to swap them over

Ok, so the problem here is solved actually.

I was very aware that then i disasemblied the engine that the Vanos unit should not be mixed whatsoever, i even put them in their separated bags an marked them with Outlet and inlet.

Well guess what? i somehow managed to mix them then putting it all togheter, haha.

Well, anyway, the car is working fine now smile
