Hello, I’m looking for the workshop manual or circuit diagrams for my 407 Coupe 3.0 HDI I have a sporadic error that the friendly Peugeot employees don’t find: Have a 407 Coupe 3.0 HDI Built. 2010 Lief until a year ago. Then the start of the nightmare. At the start attempt comes a beep and the message “gear defective” PNDR error. No starting possible. After several attempts he started and went with the error “gear defective” into the emergency program. The friend wanted to change the control unit because he did not get access to the control unit. Then the error was gone again. The error came back months later: Can not start and shows PNDR errors. With the customer service then no problems and no errors can be found? Next round: Attenuation setting came defective and gearbox defective I started and lötzli The last two weeks then in the morning no problem, at noon error with emergency program and in the evening no problem. Then again 5 days rest. Today at new Peugeot expert then read out error memory. There are following errors in it: P0606 ECU Status: Interval, Characterization: internal Fheler Steugerät Injection Ignition U1308 Error Control of the transmission on the CAN network, received value wrong U1108 Error Communication with the motor control unit, status: passed end, Ch: No signal U1108 Error Communication error with the motor control unit or the cut-off control unit of the drive train, status: Temporary; Ch: No signal The error spring damping control is not found in the fault memory. Does anyone have an idea? And more important: Who knows where there is a workshop manual or circuit diagram?
