The coolant should be replaced every 2 years, but no real need to do a system flush. BMW recommends automatic transmissions have the fluid replaced every 100k miles. Prevailing forum wisdom is more...

I replaced mine about 2 months ago. It's pretty easy if you use hose clamping pliers so you don't have to drain the system. Out of curiosity, I did disassemble the control valves. It actually...

Sounds like it could be the Center Support Bearing. Normally this noise is worse at low speed.

They really aren't hard to tighten or replace. You need a torque wrench and external torx drive sockets. (I think 4 are E15 and 2 are E12, but I'm not positive). The front 2 are tightened to 113...

You really don't need more than standard sockets, external torx sockets and maybe a short wobble extension. It's a little tight getting the actuator motor off, but it's not super difficult.

Were the codes thrown before or after replacing the vanos seals? It is possible (if you are lucky) that the exhaust cam sensor plug wasn't fully plugged in or has some oil in it.

Of course it is going to be whatever its going to be, but center support bearings seem to fail far more often than the U joints on rear driveshafts.
