I copy and paste a comment from clichuk on the Peugeot forums with regard to a 3008.
when i come to a standstill on a fairly steep hill, i break, the engine stops,
then when i lift my foot off the break i <a href="http://viglink.pgpartner.com/rd.php?r=5316&m=1046747013&q=n&rdgt=1387727166&it=1387899966&et=1388331966&priceret=38.00&pg=~~3&k=d9aaec1d2938396e564d67c1fe37e770&source=feed&url=http%3A%2F%2Fwww%2Eamazon%2Ecom%2Fdp%2FB00546KUDM%2Fref%3Dasc%5Fdf%5FB00546KUDM2788672%3Fsmid%3DA2DILQZLMPRJFH%26tag%3Dpgmp%2D51%2D01%2D20%26linkCode%3Dasn%26creative%3D395109%26creativeASIN%3DB00546KUDM&st=feed&mt=~~~~~~~~n~~~" target="_blank" rel="nofollow">roll
back</a> straight away until the engine kicks in and i can
accelerate.
if i do exactly the same but disable the eco mode so the engine
dose not turn off, the hill start works and there is no roll back.
the
service department have said the car is working within its operating parameters
and suggested two things:
1. use the hand break. this is fine but as soon as
you apply the hand brake the engine runs meaning the start stop tech is a waist
of time.
2. be quicker getting my foot on the accelerator.
This is my problem and it appears to be a combination of EGC and Stop Start I know now you cannot assume its going to work.
