Hi there, my Panda dumped all the gearbox (Dualogic) oil on the road and is now stuck in neutral, why would this happen?
I had the clutch and oil replaced about a year ago.

Cheers
 
there is a difference between the dualogic hydrolic fluid and the actual gearbox oil.

The cause can be several things, from a leak in the fluid container, to a broken seal or pressure regulator.
 
Leaking hydraulic oil?

Your going to have to find where it's leaking from

Clean, top up and inspect

Say it's the actuator, just replace it

Reseals don't last long

Sounds like your going to be in the hands of a garage, unless you want us to try and guide you through fixing it yourself
 
Unilkely to be cost effective on a 169 Panda.

That new OEM

Seen them for £90 but not in the UK

Some cheeky people are selling the same part for £300 seconds hand, and rebuild washer kits for £200

Unfortunately unless you are going to do it yourself

A garage will normally charge like a heard of elephants because they know there not many people repairing them

I only used this as an example as it a common place for the to leak


Could easy be somewhere else

If it's possible to buy a serviceable aftermarket actuator for anywhere near that kind of money, then that opens up the possibility of repairing cars which would otherwise not be economically repairable.

For most folks, though, the real problem is finding a garage reasonably local to them that's willing and able to take on a dualogic repair and give a decent warranty on the work. Once a car's more that 6-7yrs old, a properly warranted franchised dealer repair is likely to cost more than it's worth.

Paying one garage to remove/replace the part, and then paying again for it to be sent somewhere else to be refurbished, is a nightmare waiting to happen should anything go wrong.

It'd be interesting if one of the more knowledgeable folks here would take on a scrap dualogic to see what can actually be achieved, a bit like the rebuild of the 1.3 with the snapped timing chain that would otherwise have been sent to the breakers. We seem to get a steady stream of potential donor cars.

Yep most garages will not touch them here in the uk, I don't know why there's nothing complicated in them

There is a specialist in Stoke on Trent that does an exchange, can't remember who or how much he charges

I suspect you're thinking of Carl at CD Motors in Stoke; he advertises on ebay and charges £600 to refurbish your actuator with new seals.

If you've removed it yourself and it subsequently fails, then presumably you can send it back to him to sort out. But if you've also paid a local garage to remove and replace it, you'll have to pay them again in this situation.

And if a VAT registered garage sends it on your behalf, then they'll have to charge you VAT on that £600 (assuming Carl isn't registered for VAT).

Your car will be off the road whilst all this is being sorted, so you'll have to arrange alternative transport. And the local garage may not be too pleased about having it sitting around on their premises whilst they're waiting for the part to be returned, and may charge you storage.

It's understandable that many garages can't be bothered with all this, and it's also understandable that some folks with older cars just cut their losses and scrap the car.

They're not even hard (or particularly time consuming) to remove (apart from draining the coolant to get a bit more room, although I have done it without).
DIY rebuild is theoretically easy, but very hard to find seals at a sensible price. Done one (using mix of seals from 2 failed units) and it's still going. Got another 3 in the Round Tuit pile, waiting for me to find seals.
What I have found when messing about with Dualogics is that usually it seems to be one of 3 things that starts the problem, and it all goes wrong from there...
1. Accumulator failure. Owner keeps driving until motor starts blowing fuse or stops altogether.
2. Clutch worn out, owner keeps driving.
3. Gearbox input bearing & seal failure, owner keeps driving.

1 often leads to motor failure, or bad advice to "top it up" which often seems to go wrong on unexpected ways. Also bits of the accumulator membrane end up in the fluid and cause other problems.
2 seems to cause failure of the clutch actuator seal, sometimes followed by clutch replacement but no repair of the clutch actuator seal, leading to more problems.
3 stresses the seals in the change actuators, leading to leaks, as the gear shifting action is out of specification (i.e. too sloppy or too stiff, or expected movements do not result in selected gear)

I've always found the units to be very reliable unless abused, but I understand that others feel differently.

Willing to donate a unit to someone who is serious about trying a rebuild, but ill be pointless unless you have access to a set of seals.

PS OEM accumulator is Magneti Marelli, as are other parts.
 
Thanks for all the replies, any repairs on a Fiat are very expensive, the clutch cost me over R13000.00 (in pounds about 600 pounds), and the fuel airflow sensor about 100 pounds!

I am no mechanic so I don't know if it is the gearbox fluid or dualogic fluid, but the fluid looks clear and very thin.

The car is currently stuck in neutral, can I tow it?

Thank you, but I am not a mechanic and will break more than fix it, I will have to get someone to look at it, but here in SA it's going to be expensive.
