B mode dose not want to work if ACC is left on – so down to me – but problem solved.
Just back from 250 mile round trip.
Car averaged 3.8 – ACC on – a/c on set to 19c – music on.
Mostly down the M4 from Surrey to Newport – ACC on 70 which was achieved for the majority of the journey.
There are issues with the ACC – on two occasions on the m4 it decided to reduce my speed to 50 – I was quite quick on the acceleration so not a problem, but a bit weird if you are not expecting it.
