Technical Dualogic won’t work when cold

[gareth111278]

Hello
Ive got problems with my mother in laws Panda 1.2 petrol dualogic.

It moves very little, probably been standing for a month. Went to it the other day & it refused to engage either 1st or reverse. Just clunked, went bing bing & stayed in N. The temperature was about 3 degrees C. I left it running until the fan kicked in, still no joy. so I switched it off & went back to it an hour later once the warm engine had warmed the gearbox a little & it worked fine!
Same thing today.
The gearbox oil is new & there’s enough dualogic fluid in it, I even added 50ml to make sure!
The pump starts & everything else seems normal.
Obviously something doesn’t like the cold, anyone know what it might be?

Check the brake lights hot vs cold

That’s a though. If the brake lights don’t work the gearbox ECU assumes you’re not pressing the pedal & won’t engage a gear. I’ll try in the morning & check them if it’s not behaving.

Brake lights work ok.
It’s so annoying because ones it’s warmed up & gone into gear once it never misses a beat

Had similar problems a couple of times on different cars. Both times it just went away and didn't come back.

I think once it was just a low battery problem, as the starter sounded sluggish. I put the battery on charge and left it overnight. When I started it the next morning it was fine, so didn't give it another thought.

The other time I think the clutch plate was probably stuck to the flywheel. Didn't bother to check it out at the time, as it was *really* cold and everything was iced up (I was only going to move the car further up the driveway, so just left it where it was).
I guess I could have checked it by putting the ignition on but not starting, and then rocking the car to make sure it was free to move.

You need to pull the fault code really. You’ll be stabbing in the dark otherwise

irc, yes I’ve had battery problems with it, new battery sorted it.
Good point about it being the clutch plate stuck, when I try to select a gear I hear the robot clunking. I wonder if it’s trying to disengage the clutch

Most Easterly Pandas, yes I suppose that’s a good idea. I doubt my £20 OBD will tell me much. Might need specialist attention

I know very little about the dualogic. never had one


the only suggestion I have is can you hear the pump prime when you open the drivers door.


there must be half a dozen similar threads in the punto and 500 sections with no resolve


maybe a post in this thread also https://www.fiatforum.com/grande-punto-guides/439619-dualogic-troubleshooting-guide.html and the right person will see it

MultiECUscan software will enable you to do everything with it that a main dealer can

Yes the car is here!

I’ve just found a guy in stoke on Trent that offers an overhaul of your robot unit for £450. He’s ex Fiat dealer & the listing inspires confidence!
Lot of money but if you add £450 to the £500 value (?) of the car what can you buy ?

Thanks for the offer, I’m hoping the expert in Longton will get back to me. I can take the car there & stay at my parents for a couple of days, obviously post lock down!
