How long does EDR last in a car?

There are a number of factors that affect how long the data recored by your vehicles EDR will be kept for. Our advice is always to have the EDR downloaded as soon as possible, to give you the best possible chance of capturing that data. But in terms of specific times, we have found the following:

  • Data will be kept indefinitely,
  • Data will be deleted after a defined number of key turns (car key),
  • Data will be deleted after a defined number of engine starts.


The time the data is kept for will be different on a car by car basis as the manufacutrers will determine how long the data is kept for and what will result in the data being deleted.
