Problem with gearbox Hello, last month I bought C4 Picasso 2013 (68kW, 1.6HDi) from private seller.

It's farmed out to people like the AA (Automobile Association) or RAC (Royal Automobile Club) in the UK (whichever charges least probably) - don't know who it Joined: Mar 23 2012. Location: Scotland. The car has been juddering at low speed (2010 1.6HDi EGS) and so tried the hard reset method tonight. Stopped, put on and then off the handbrake, and then floored it to just over 40, and then cruised at 40. Blimey, for a car that size, with just a 1.6, it fair shifts! qp7vOw.
