🎐 Citroen C4 Grand Picasso Gearbox Fault

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. It will need some investigation, but the P1755 fault for the Piloted Manual Gearbox states: Fault Code: P1755. Clutch Jammed: Coherence. Description of Fault: Clutch actuator fault: incorrect position in relation to the reference value. This can display with the wheels free and with the engine running. It can occur: In gear changing phase; In SIYAMED. Sun Mar 25 2012, 02:37am. Member No: #24589. Joined: Mar 06 2012. Location: london. Hi, My 58 Plate C4GP 1.6 Hdi VTR+ EGS has some gearbox issues when I change to reverse gear, the gearbox snatches/judders and the car seems to go back a bit. I bought Lexia for gearbox calibration but the process fails at programming the biting point Hi, I own a GPC4 1.6 VTR+ 2009 with 50k, I have three fault codes which are: P1701, Gear ratio incorrect. P0868, Lack of oil pressure and finally P0948, Electric pump unit electric motor control. Am I right in saying the 1st is clutch wear And the 2nd is due to the 3rd fault I listed. Symptoms are service light coming on, faulty gearbox sign It is a 2011 Grand Picasso, with 2.0l HDi engine and EGS robot gearchange. Has done under 80,000 km. Now stuck in gear - can't change back to neutral, so can't even try starting the engine. i have suggested he contacts Tim the mobile mechanic who has posted on here (Fenchiemech34 aka French car guru), but in the meantime - any suggestions? 2012 C4 Grand Picasso diesel with egs gearbox, 55,000 miles. Recently, I've found the car will accelerate normally in 1st, 2nd and 3rd gears, but the clutch seems to slip when it selects 4th and 5th and to a lesser extent 6th gear. This can be interesting when trying to move into the space between two artics when joining a dual carriageway! Visited Marsh Citroen yesterday was loaned a Xsara Picasso diesel which was just an old runabout but I had a Exclusive model previous to the C4 so not a problem and it was better than shanks pony ! Our car was tested for 9 miles by Dave and we then drove the 40 odd miles home NO PROBLEMS it seems to be cured but will keep everyone informed. 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. y0okuq.
