Your Cloned Dp3 Didn't Properly write to the EZS module that's why it prioritized the highest mileage stored in the module to show on the dash after 7 seconds.
China does not throw away anything. so when component manufactures have components that are out of the manufactures datasheet tolerance level they sell them to the clone market.
these components are partially defectives and/or not stable! This is usually caused by an internally biasing issue inside the wafer. That's why those cloned tools will work perfectly fine one day and fail on the exact same year make and model another day.
if you have a professional grade oscilloscope and monitor out signal of those cloners you will see that the output is very noisy and dirty compared to the original tool

The reason why you see 999999 is because the software version of your instrument cluster has beed updated at the dealer. You have 2 options now:
1. Install a CAN filter for the Ezs.
2. Renew and readapt the Ezs.

In both cases you need to redo the cluster, but it is easy to do it by diagnostics.
