Not sure about your cluster, but mine only has 15 tests. Just note that when you swap clusters, the EEPROM and the coding plug will not match. This will illuminate the manipulation dot next to the mileage display. If you hold in the reset buttonfor 4 seconds, the manipulation dot will be cancelled, but IT WILL OVERWRITE THE LOWER MILEAGE and the higher of the two mileages will be saved to the car's computer. It's test 09 on my cluster, again, I'm not sure about yours if it's different. Here's a link to where I found this information:
