New ISTA BMW Diagnostics Kit

At A1BN, we now use the same professional BMW diagnostic system equipment as main dealers to diagnose faults and run resets/fixes. The BMW AG ISTA BMW Diagnostics Kit system automatically updates from the BMW AG central server to ensure all the latest updates are available.


Diagnostics is our key area and with more electrical and computer controlled items being fitted to cars we are seeing an increasing number of faults occurring.

Fault-finding and rectification requires expensive dedicated test equipment and well trained technicians of which we have both. This places us in a strong position to provide "Diagnostic Services" to the general public and trade alike.
