Distance impulse number (K number), reading/confirming
WARNING: This page is about a different variant/trim than selected.
Distance impulse number can only be read/confirmed on VDO instrument clusters.
NOTE:
- The distance impulse number is a constant used to calculate the speed indication and distance travelled.
- The distance impulse number (K number) cannot be changed using the "Adaptation" function. To change the distance impulse number, a code that corresponds to the vehicle engine/gearbox combination must be entered using "Code Control Module" function 07. Vehicles. 05.99 > 05.00. Refer to Instrument cluster 05.99 > 05.00, coding (function 07) . Vehicles 05.00 >. Refer to Instrument cluster 05.00 >, coding (function 07) .
- For instrument clusters with mile indicators, the distance impulse number is shown in kilometers. The trip impulse number for mile values can be calculated as follows: Trip impulse number for kilometer values x 1.609 = trip impulse number for mile values.
- Press the -C- button on the VAG 1551 to abort the "Read distance impulse number" function.
- Connect scan tool VAG 1551, select operating mode 1 "Rapid data transfer", switch on ignition and enter address word 17 "instrument cluster".
- Press -Q- button to confirm input.

- Read/confirm distance impulse number in accordance with production date and/or vehicle engine/gearbox combinations. Refer to code tables: vehicles 05.99 > 05.00. Refer to Instrument cluster 05.99 > 05.00, coding (function 07) . Vehicles 05.00 >. Refer to Instrument cluster 05.00 >, coding (function 07) .
