I believe this is way too frequent and also lasts too long. I drive car long distance at least weekly, like I mentioned above. Missus was doing 10-11 miles round commuting trip with minimal traffic and steady 40mph run on cities dual carriageways.
I am having it serviced on Wednesday and will have it plugged to VIDA to see if anything bad comes up.
I did long cruise at 75mph on cruise control today and on the way back at around 110-120th miles of the trip bloody regen cycle kicked in. Momentary consumption doing 70mph around 8-8.5l/100km going flat vs 5-5.5l/100km with regen off. Range decreasing at alarming rate.
I will mention your suggestion to the service department. Thank you for your reply.
