We're sitting here in our immobile 2014 2.3 Ducato 150bhp Comfortmatic x250 Motorhome after a frustrating day. We had packed up to leave site at 11:00, went to start the engine - nothing. Then an error "Check transmission see handbook". The gearbox is stuck in first so the engine won't start.

Fiat Camper Assist/ RAC came out after a couple of hours and read OBD codes including P1810. Tried disconnecting the battery and other tricks but no joy. Jacked up the front and rocked the wheel - still the same. Requested recovery. This proved difficult as we are parked on gravel nose-in so getting the van onto a truck has defeated us for the time being. Also checked fuse F05 for the robotised gearbox pump as suggested by our local Fiat Commercial garage but it had not blown.

I haven't found anything about Ducato Comfortmatic stuck in 1st gear. Any one else had this?

I haven't come across this issue yet, though a few years back they had a major issue with the gear selection actuator breaking up, seen as this component controlls gear selection this would probably be the next place to look, I take it the hydraulic fluid levels are okay ?

FIXED!Re: 2.3 Ducato Comfortmatic code P1810 won't start. stuck in 1st

Ok, the problem has been fixed my a mobile engineer arranged by Fiat Camper Assist (i.e. RAC) together with telephone assistance from a technician at Adams Morey Portsmouth.

The pump operating the Comfort matic robotised manual gearbox was not working. This was determined by listening for the pump whirring when the drivers door is opened (the system readies itself by pressurising the system before you enter the vehicle, see Fiat manual). I had already checked fuse F05 as advised my Adams Morey and it was intact. The fault was traced back to a connector located under a cover behind the fuse box under the bonnet. See the thin red wire in the mid right of the attached photograph which enter the connector. Wiggling the connector fixed the problem.

Thanks for the reply. Hope this helps someone else down the road.

there is also a multi plug that gets water ingress just to the left of that red wire and corodes.

hi all .sounds like more water ingress problems I don't know why fiat bothered to fit a bonnet because it doesn't do any good when the first mini's came out the rotor got soaked first bit of rain game over

To all Fault P1810 -79 Fiat ducato Stuck in gear cannot start !!
Hi!! To all fiat ducato mortorhome and selespeed user IF you’re stuck in gear and cannot do anything to start the car Try this before your machanic tell u to replace the dualogic robotise gearbox Which would cost over $20,000 hear is the way to save money!!! Check your fault code and if u can’t find anything related Check your fuse in and out side check and reconnect all the terminals connection check for water damage and and burn or bad condition then spay some contract cleaner & reconnect backCheck your Robotise fluid Open driver door make sure u can hear the pump running and if u cannot hear hydraulic pump running then check your fuse and wiring from the pump connection if pump works normally Activate the hydraulic pressure pump with scanner ( I use autel Maxyis ) then turn the pump on but not too long because if will build up the Accumulator pump up to 80 bar or over 1,000 psi it will be dangerous for u sand can damage the system operating pressure is around 45 bar if too much on your life data can try to change gear but if your gear not operating then remove pressure sensor slowly do not remove all the way out because you are dealing with 1160 psi pressure so make sure to remove the high pressure pump conection that has a smaller red wire near the fuse box on the transmission wiring room main plug first then let it pip out slowly so when you’re confirm that the pump work then Check your solenoid by activating the solenoid by using 12 volts battery pull the electrical plugs out of the back and apply 12v. power to the pin and see if you must hear a clicking noise each time when u connect to the battery and start to touching click click to the battery but do not leave it more than 1 seconds check for all of them and if one of them doesn’t make noise rotate battery connection and try again if still no clicking sound then pull the solenoid out then try to clean on the bench with brake cleaner and reapply power again for 2-5 mins and if you can free up solenoid you can save a lots of money by reusing them but if u cannot get it click you can check from online with trusted website with unique correct parts No. And if that faulty solenoid were the one that controlled the line pressure after u fix or replace you system should complete recallabation and it will start to working and control the clutch when pressure line and you can get out of gear and able to start the car again ( failure pressure solenoid can have symptoms of transmission stuck or not start because if pressures cannot get pass from the solenoid release valve then your system will not operate any gear change in live data may say that line say that u have pressure in the system not working you will not able to operate any gear change and also cannot complete relean the system Go to Clutch replacement then try to bleeding the clutch and try to let it complete Calibration and if scanner says that Fail to complete depressurisation or Unknown DDE and make you think that is an ECU or TCU module under the dash fault but check your connection again and make sure power and earth are working hope answer will help you guys saving a lots of money Poom From Chardtone prestige mortor Australia Goodluck
