I initially ran into problems with the car rolling backwards slightly in traffic and blamed these on the operation of the hill-hold assist option. However, on further investigation, I believe the start/stop system is to blame.
Unusually, compared to other cares I have owned. the s/s system will stop the engine before you come to the full stop (it seems to shut down as the car reduces speed to 4mph under breaking conditions).
I have noticed the engine cut out as I roll up to a give-way junction:
1) Approaching junction, foot on the brake
2) Speed drops below 4mph, the engine cuts out
3) The junction is clear, foot off the brake and onto the accelerator
4) Momentary delay and lack of power as the engine starts
5) Car pulls away
During phase 4 above, there is a risk of the car rolling backwards - which is why I initially attributed it to the HHA system.
Does anyone know if it is possible to code this feature so the engine will only cut out once the car has come to a complete stop? I don't have anything against start/stop in general, I'd just rather it only come on when the car has come to a complete stop.
The manual indicates that the system is operating normally, with the footnote clarifying that the mode of operation will vary between countries...
While the manual also includes this passage, I've not managed to master the pressures required. The only time I've encountered the scenario below is when I've braked very gently coming up to some lights and had to give a firmer jab of the brakes to get the engine to cut out. I've never managed to do the opposite and keep the engine running when intended!
