On my 2002 Passat there is a reset button on the underside of the Windshield washer arm. Pushing that will clear the trip computer settings, per display.
It is flashing to remind you that is time for service. Original ones had a button on the back to reset it; newer ones did it automatically after an hour or two.
you will need to leave the radio on for 1 hour so the radio can reset itself then you can re-enter the code.
I have an 04 and I disconnect the battery terminals for about a half hour. Just did in within past week. You'll need to reset your radio stations also
convert 1bar to meter cube per hour
0.0002777 meter per second
You divide by 3600 - since an hour has 3600 seconds.
1 meter per second = 3.6 kilometers per hour
You can accomplish this by removing one lead from the back of the hour meter. It will be a DC voltage circuit.
1 meter per second = 3,600 meters per hour = 2.237miles per hour. (rounded)
You multiply by the number of feeds per meter and by the number of minutes per hour.
(1 mile/sec) x (3,600 sec/hour) x (1,609.344 meter/mile) = 5,793,638 meter/hour
In the same place the regular kilowatt hour meter was installed.
