I have a 2008 Grand Picasso 2.0 petrol. Automatic with the paddle shifts - Gear Selector with P-R-N-D-M. I use this as a run around car and ive lived with this problem for ages, but i want to get to the bottom of it, let me explain. Everytime i start the car from cold, i head off on my journey and within 200m, a clunk, and "faulty gearbox" appears.Citroen C4 2008 Mk1 Automatic Gearbox Control Module 1.6 Petrol Ecu 9661983980 (Fits: C4) Pre-owned | Business.

Citroen garage found code P0925 gearbox fault gear not engaged. They reset the gearbox programming ECU. They reset the gearbox programming ECU. They did a roadtest but no fault - fault tends to happen after the engine has warmed up although now happens soon after starting.
I've got this fault with gear selection on my 2008 EGS picasso. I've finally got a fault code P1704 - 'gear selector coherence fault'. Which apparently is "digital TRS faulted to transmit states in KOEO/KOER whatever the heck that means :/ also another one popped up briefly: P1715 but cannot find any reference to these codes on the site.
