Dr Vanos Cryo hub or Beisan?

[Obioban]

If it ain't broke don't fix it. If tabs are fine I wouldn't mess with it but if you do then re-drill the disc.

I would definitely not replace a functioning solenoid with someone's melted and repaired solenoid that many have had issues with. Wait until it fails since it's easy to diagnose and repair, then decide.

This is all terrible advice and should be ignored— absolutely, 100% you should replace the pump disk BEFORE tab failure.

Solenoid failure can’t nuke your engine when it fails (like a vanos tab can), so less critical, but I’d do it while in there so you never have to worry about it. The stock solenoid will fail at some point, and throw the car into limp mode. If you're 500 miles from home at the time, that's a PITA. The Beisan unit likely never will.

My 2002 M3 vert is in the shop for a valve adjustment with 112k miles. Last one was done at 91k so I know it is a few miles early and the hub and sprocket bolts were fine. I am thinking that while he is in there for the valve adjustment I will have him at least check the Vanos hub. I have some questions:

1. If the hub and sprocket bolts are fine, should I just leave well enough alone? I don't track or drive too hard.
2. If I decide to upgrade the hub, should I go with the Beisan hub? It is half the cost of the Dr Vanos cryo hub. I have heard nothing but good things about the Beisan product and support but my mechanic is recommending Dr Vanos.
3. Do I need to replace both the hub and pump disc? If the hub is not cracked should I send the pump disc to Beisan to have it redrilled? There seem to be conflicting opinions kicking around on the web

how about the solenoid pack? 112k currently on car, no codes, replace or not?

I would.

Beisan,every time.

What’s happened to this thread - remember I had posted answer a few times?

Don't see why you'd need a new hub if the old one isn't showing signs of wear or cracks. IMO if you're at the preemptive stage here I'd dare suggest a Beisan re-drilled pump disc would suffice.

This was confirmed by a call to Beisan. They were very helpful on the phone
