Press “ Execute ” during the pre- procedures :

Using MD-EVO, clear DTCs.
NOTE : Following the update, in very rare cases, the following message may appear on the screen.

This message does not indicate any technical problems with the car and simply suggests that an extra
urban cycle should be performed at cruising speed to facilitate spontaneous GPF regeneration.
Technically, this message is activated when the GPF is about 50% full, in a non-critical condition. In some
cases, the message may appear on pre-delivery vehicles if frequent cold engine start/stop cycles have
been performed. Again, this message is to be regarded as a technical suggestion and should in no way be
seen as a vehicle malfunction.
The reason why this warning has been implemented in this new software version is to inform the customer in
good time so that the vehicle can be kept in perfect working order. Therefore, no further action is required
by the workshop should this message appear following the update. TCM SW Update (some MY23 only) We
also ask you to inform the customer of both the new warning function and the possible need to drive an
extra-urban cycle. For this reason, any request for supplementary work under warranty concerning this issue
will be rejected.

If the affected vehicle also requires a TCM software update (action “ ECM + TCM Software Updates ”), proceed
with the instructions on the next page “TCM Software Update”. Otherwise, the procedure is complete.
