These 3,4,5 series BMWs are some of the best handling and safest
vehicles on the planet. The M62, M62TU, M54, M52, & M52TU engines
are bulletproof, and the suspensions superb.

Yet, part of owning a bimmer is fixing it yourself. Otherwise you'll
go broke with the repairs. I know of scores who have "repaired"
their trunk wiring loom - but I don't know of any who went to the
stealer to have it replaced.

I was only answering the question of what BMW says to do.
We all work on our own vehicles so we repair them ourselves.

Cost to "repair" is about $20 give or take - but the real question
is why it breaks in the first place. It looks like, from the discussions,
a combination of poor choice is insulation plus a badly designed snorkel.
