General Dualogic Issues

[Broker1]

Hi all, It had to happen and I was just gritting my teeth waiting for it. The 1.2 Sport which my wife adores threw itself into "N" today as she came to a stop at a junction. She turned the car off and on and it worked fine.


I believe this is the start of issues and I would like to keep on top of them and so with this in mind what are the steps to take. The car is a 2008 and so I am on my own. Are there any prelim checks I should do or should I just get it into a garage right now.


From what I have read, garages are a bit "hit or miss" with dealing with this issue and some start re resetting software and this ends up in a big bill later when this doesn't fix it. Should I just get the whole thing replaced now? and if so is it the whole gearbox or just the actuator (please be gentle I am an engine novice)


If I need to use a garage any suggestions for someone who knows what they are doing? I live in South Lincs 20 mile above Peterborough.


Thanks in advance (I await the posts about sell it/should have bought a manual but the wife loves it and I will not sell it with a fault)

Welcome to the club! I wouldn't say I was an expert on the Dreaded Dualogic, but I've had 10 years + using them.
In order for the box to change into Neutral I would say that the actuator would have to have been commanded by the ECU to do so, as I don't think it can just slip out of gear.
If the command wasn't caused by a manual operation from the driver I would think it should be held in the Dualogic ECU memory. This can be checked by using the 'Examiner' or , perhaps someone can do it with a Multiscan.
I think your wife did the right thing by switching it off and on, just hope that it was just a hiccup.
If you look at fcconnect.co.nz/wp-content/uploads/Fiat-Dualogic-M20-Training-Manual.pdf There is an extremely useful manual on how it works and how to work it .
I've had some useful tips from NZ how to work on it without any technical wizardry too.Things that Fiat agents didn't know.
Best of luck, When they work correctly they are great BUT they can be rubbish

if it starts to fail the only way it will properly be fixed is to replace the whole hydraulic actuator unit, the part costing about 1000 + GBP.

regarding prelim checks, check the oil level of the Dualogic system, and check for any leaks. If you see a leak and the oil level is low, you are in trouble, get the system changed as it will fail eventually.

if it only went into netural once without any flashing gearbox warning light may not be the end of the world if oil levels are ok, meaning you still can drive it for now. If it starts happening often, then you can be more concerned.

I'm saddened, but not surprised, to read of another potential dualogic failure.

I've moved this discussion into the 'one and only dualogic failure thread' (the clue is in the title).

Please continue the discussion here.
