i have problem with my c4 2007 semi automatic gearbox CFC300P, gear stays on neutral N "gearbox faulty message" car sometimes start sometimes not but im not be able to change gear. on technical section, the most times im not be able to perform clutch bleed , depresurise /presurise , also im not be able to reprogram the gearbox (i hear a crack sound and it stops , sometimes it goes to 1st gear and it stops immediately and i get an unknown error message ) also the clutch is trying to presurise the system every 20-30 seconds it goes from 29~32 bar to ~50 bar and it drops gradually back to 30
there is no visible leak.
i use delphi ds150. ( also the same results with lexia )
