Hi.
I just replaced the battery in My X5 and when I try to start the
engine, it asks for a code. Any thoughts?

The vehicle (hopefully) came with a little card with the radio code on
it. Check your glove box.

When MY car is asking for the CODE, it wants the code that tells the radio
that it hasn't been stolen, and is now living in a strange dashboard. Your
Owner's Manual package should contain a manual for the radio, that manual
contains the CODE key.

If not take it to a radio expert and get the code changed.............

It's a lot easier to go to the dealership and have them look it up ...

I should mention that if the wrong CODE is input several times (I'm not sure
of the count, but I've heard that three attempts is all that are allowed),
then the car must be set with the Ignition left at ON for an extended period
to reset the Attempt Counter.

I had a weak battery, and the wife and kids attempted many times to input
the CODE, and eventually the car would not accept any input at all -- even
the right one. I found that if I left the ignition set to ON (RUN, but not
START -- obviously) for about an hour, I could then plug in the correct
CODE, and get the radio back.

That's the pattern: three strikes (incorrect inputs) and you're out.
To get another chance, the radio must be *powered* for an hour.
Obviously, you can drive the car during this time, but the power must
be on *continuously* for at least an hour.  Then, you get 3 chances to
screw up again.  ;^)

Ummm... C.R.. we're talking 21st Century BMWs - this is the code to
disable the car starting, not the radio. The radio codes are so 20th
Century (no modern BMW uses them..)

Well, my 20th century E34 had a feature in the OBC that allowed a user
to enter a code that would prevent starting the car.  The problem is, it
was user selectable.  I never used the feature so I don't know what
happens if you get locked out.

My cars have that too. If I set the code in that location, I'd be embaraced
to ask you guys what it was, and shocked if you knew.

I guess you're right - so why am *I* the only one talking about radio
codes here getting my butt chewed out?

I did write up a chewing out for the other ones, but somehow it didn't
post. I'll try to be more diligent on that in the future
(equal-time-chewing sort of thing.)
