Car's back from the dealer...
The brake noise is normal - they even gave me a copy of the TSB describing it. I still don't understand the difference from my 03 HCH, but oh well...
Took care of the ECM recall. CD player was skipping - they've ordered a new one.
Rattles in the A-pillars - there's a TSB covering this (Number 04-301, May 2004). It's important to tell the dealer about this TSB, otherwise they'll do a generic rattle search and tell you they couldn't reproduce it
