Hi all. My better half has today just got an 07 307cc. Lovely car and drove perfectly on the test drive and the way home. However it's now started displaying the abs and esp lights. I'm not to worried about that but more this. When she brakes a little harder than normal, say coming up to a junction and stops, when she goes to pull away the revs go up to over 3000 and then there's a thump and the box engages and pulls away. Doesn't do it in normal driving!

Take it back to seller and tell him its not roadworthy.

That is most likely faulty hydraulic valves in the auto box. Common issue with many peugeot auto boxes... AL4, AM6..
Take it back and get a refund.
