[Biturbos4] Lack of heat in B5 series car - any thoughts?(commonproblems, etc)

[George]

Careful with this one.  Many heater cores have a back check valve that will
not allow a reverse flush to happen. I went through this on my '91 200 20
valve when the wrench bender installed the hoses reversed, and blew out the
core. If you shake a new core, you can hear the valve rattling.
