Volkswagen: 2001 passt 1.8 turbo, battery terminals, throttle body


Question
can i replace the battery myself or does the dealer have to do  it someone told me if i disconnect the battery the card will have to be "recoded" and will not start

Answer
The radio will reset itself to "safe" mode.  If you don't have the 4 number code, it will return to normal in 24 hours.  The throttle body may lose adaptation and the engine will start hard until it readapts.  To avoid this, there are devices you attach to the battery terminals to keep voltage while the battery is out.  Any place that sells and installs batteries (like Interstate or Sears) should have one.  The battery heavy and hard to pull out.  For the $15 install fee, I'd let someone else get a hernia.
