Replaced battery on 98 Porsche Boxster and now odometer is wrong

The battery is located in the front trunk of the car, under a cover just below the middle of the windshield. Either remove the battery or disconnect the positive (Red) cable and hook up a battery charger. You can get a battery charger at sears or any auto-parts store. Get one that automatically stops when the battery is fully charged. If you have to charge it after each trip it could be that the battery needs to be replaced or that you need a new alternator.

Sounds like a bad engine temp sensor to me. Also could be a intake or EGR leak causing the 02 problem

Press the reset button x 2 for 2 secs each.

hi,

Try this procedure. Porsche can be hit or miss with reset procedures. Sometime a Porsche scan tool is needed.

1. Enter the vehicle and make sure that all doors are closed.

2. Push the odometer reset button while turning the ignition key on.

3. Continue holding down the odometer reset button for approximately 10 seconds until the "Service Reset" message appears in the information center.

4. Release the odometer reset button and press the reset button on the bottom of the wiper stalk.

5. It may take a few attempts with this procedure.

6. If the light is not reset, then a Porsche compatible scan tool will be required to reset it.

Check the fuse at the driver's knee panel.

Only the trip odometer should reset to 0.0 after battery replacement. It's unavoidable without using a 9V battery plugged into the lighter socket. The primary odometer certainly should not. Did it?
