Not true. I am a Dealer Expert Technician and I have seen this many times before, it depends if the internal ecu capacitors have fully discharged as to how long the car can last without it but flashing mileage reading is a definate indication proxi alignment is required. Proxi alignment should be carried out every time the battery is disconnected and every time an ecu is replaced or disconnected.
