Purion odometer error.

[fallingoff]

Recently purchased a Cube using the Purion unit. It had the "magnet" mod but has been returned to standard. I fitted a second computer to compare speeds, etc. And also get an accurate reading of distance because the Purion is not increasing the odometer as it should. Tested today the Purion read 2 miles whilst the second speedo read 9.5 miles, which is correct. The speeds are comparable but the odo's are far apart. Googled to no avail ,TIA.

Bosch got back to me quickly and were very helpful. They launched a service request case and asked that my LBS use that to investigate FOC ,with the stipulation that I could provide the original purchase receipt, I couldn't so they just updated the software, there were no issues found and it's working correctly now.Thanks.
