The diagnosed the fault as " somthing breaking up in the actuator" There was debris in the oil in the actuator tank. Result new actuator £950. The garage contacted Citroen because the age and mileage of the car and the problem started just out of warranty. Upshot the nice people at Citroen are replacing the actuator for a large discounted price.
My 2016 GP has developed the following problem. Everything ok for first mile or so then manual gear selection with paddles will not work and cannot select manual with lever it stays in auto. After about another 10 miles display pops up "Gear Box Fault etc". Local dealer has diagnosed and says requires new " Actuator 9802017380" at £1000 plus !!!
To help others I had had the following faults. ABS Fault, Brake fault, EPS fault, Depollution fault, Handbrake fault, Gearbox fault, Power steering fault. EGS Gearbox would only change using paddles from 1st up to 3rd. To get further I had to accelerate and drop into Neutral and then back into Auto mode to get 5th or 6th. Gearbox changed down fine!
The fault turned out to be a corroded orange wire from F6 above the battery to pin 3 of the 28 way connector on the gearbox ECU. The corroded wire was in the loom behind the battery and appeared to be corroded by battery acid (I'm not sure how) or from water entry into the loom. I believe it's a common fault looking at the forum.
An update on the gearbox fault. I took the car to Citroen Birmingham and they diagnosed a problem with the "electro pump". It had ceased and was blowing the fusebox. The hose pipe connected to the pump had bursted too. The irony is that my independent warranty company (Click4Warranty) 5-star, does not cover that part - very upset.
2010 C4 Grande Picasso gearbox fault By Alan Sheard, August 18, 2023. 0 replies; 100 views; Alan Sheard Citroen grand c4 picasso 64 plate warning lights
The car didn't start and on the car display appeared Gearbox fault: Have the vehicle repaired and Parking brake fault: Have the vehicle repaired. I called someone with a diagnostic tool (not Diagbox or Lexia) and he said there is no communication with the gearbox. Possible causes: broken wire or gearbox ECU faulty. All the fuses are OK.
It's 11 years old so I have no idea how old the battery as I only bought it a year ago. I had a Gearbox Fault today. That was a new one. Came on with the ignition, switched ignition off and on and the fault cleared. On the subject of batteries. How the hell do you get it out? (1.6 HDi)
