I have a 2008 1.4 Grande Punto sport with Dualogic. can anyone give me sugestions on what may cause complete failure of the trans' with " gear not available " showing as soon as engine starts and no matter where I push the selector it is the same. I cannot hear the gear actuator hydrolic pump running when I open the drivers door so I don't think it is running. The interior light operates as normal as does the central locking. Is there as fuse or relay controling this? if so where are they? Where is the pump. The car has only done 15K miles.

Technical Dualogic trans' no gears available
Thanks for this. There is plenty of oil in the engine as I believe the actual gearbox and the engine share the same oil. Please correct me if i'm wrong.
I know that the gearbox gear change and clutch actuator system share the same hydraulic system. Has anyone got any idea where this is located to check the hydraulic oil level as i believe the pump that starts up when you open the door is the one that pumps up the hydraulics in this system.
Thanks.

Hi ,
I had the panda duologic,
it was basically a conventional manual g-box punto / panda with a Hydraulic system changing the gears rather than your arm and rods/cables.
someone on the panda section had issues with theirs..and a "battery-off reset" had it back to normal,
try that 1st,
2 hours should be enough,
but I tend to do it overnight.. takes less time resetting the clock then too..!!
the oil should be separate, as they do VERY diffrerent things.
good luck , and let us know how it goes,

The Duologic encourages drivers to idle in-gear with the clutch down rather than in neutral so the pressure plate fingers wear out. Check the clutch has not failed.
I'm going to try the battery disconnect tonight. Also I've got hold of a fault code scanner and I will have go with that tomorrow to see what it comes up with. I'll let you know. Again does anyone know where the hydraulic oil filler point is for the gearbox actuators is? My guess its on the gearbox on the passenger side of the car allong with the gearbox oil filler and drain plugs but not sure. Yes I have realised that the gearbox oil is seperate from the engine oil. The Fiat owners handbook is the worst I have ever come across and lacks a lot of information and quite often what is there is out of date or completly wrong. Took me ages to find the interior fuse box which according to the book is behind a removeable panel to the right of the stearing wheel where as it's behind the glove box. Wrong info is quite often worse than no info. I have had a company car for years and never had to bother with car repairs but now I do I realise how poor the quality of drivers hand books are now days they seem to assume all drivers are incompetent when it comes to sorting their cars out and I'm sick of reading " contact dealership " for such things as replaceing reversing lamp and to change the pollen filter.
the hydo oil is the gear box oil

No it's not.
Gearbox is a normal manual gearbox with normal gearbox oil.
Gear selection is by an electro-hydraulic system of actuators bolted in place of the original gear selector/clutch lever on top of the 'box and runs on specific oil (Tutela CS Speed) supplied by a pump at an operating pressure of 45-60 bar.
The reservoir is attached to the front of the actuator block, in front of the gearbox, and is covered by a heatshield which will need removing to check/top-up the fluid. It's not shown in the manual because it's something which isn't part of the basic maintainance.
If it's been working and selecting gears fine up until now, I'd probably rule out a fluid issue and be checking the fuses for the pump itself.
The dualogic system and it's operation is covered a little better in the manual supplement you should have-

Thanks to everyone. I'm still strungling with this. The Dualogic addendum refers to fuses 84, 87 & 16 but not only can I not find any reference to fuses with these numbers in the Punto hand book but I can't find the interior fuse box. It's not to the right of the steering and all I can see in the glove box is a box with a " windows mobile " logo stuck on it.
Is there anyone that can tell me where the fuse box is and I can test all the cars fuses. I got the car running by disconnecting the battery as sugested but I went back about 2 hours later and it was back to square one with the hydraulic pump not running when the drivers door is opened.
Thanks again for your help.

Dashboard fusebox in the Grande Punto is in the glovebox, to the left-hand side with a plate covering the connectors, but according to the manual, those fuses are in the engine bay fusebox (which makes sense to me) by the battery.
The Grande manual fuse numbers don't always tally-up with what's stated on the fusebox cover. Go by the location in the diagram rather than the specific number- someone in Italy cocked-up.

Sounds like either the pump motor is sticking, or the pressure sensor may be giving a false reading that it's upto pressure already.
Really need to get the error codes read to save a lot of guesswork.
