Multiecuscan

Goodmorning
this morning we plugged the new CANtierCAR device that we just bought into a 500 Abarth (ECU model: Bosch Motronic Me17.3.0 CF6/EOBD Injection 1.4 16V) and some of the lights on the dashboard of the car started flashing, airbag light, tyre pressure, engine light, ABS, we immediatly turned the ignition off and unplugged the device luckily without the device plugged into the car those lights slowly turned off, we went into the errors of the ECU and we had 7-10 different errors that were resetting and coming back all alone,should we be concerned?

Generally when diagnostic kit connected to the car one or more dashboard lights will come on. ABS is a common one. As long as when you disconnect, after resetting any errors, all the light go out then there is nothing to worry about.
