Technical The one and only Dualogic failure thread

[Nuforce]

I just had CD Motors put a new unit in my wife's 14 500. They are super nice guys and if they weren't 2.5hrs drive from me I'd have them do all the servicing on the little thing.

Glad you managed to get it fixed, and that you had a good experience with CD motors.

To help others, would you mind sharing what the total bill was?

 

[Nuforce]

Sure. £1600 including vat and fitting. I got the car cheap so I didn't mind paying it and now it will run for several years.

 

[justinsignsau]

How much are they quoting you?

I have been quoted $4100 AUD to supply, fit and recalibrate a reconditioned actuator.

They have replaced the clutch and flywheel at a cost of $3400 AUD

I am looking at a new vehicle, park the doblo and repair in my spare time.
If I sold the doblo in working order, I wouldnt get much more than $8k so its hards to justify the repair bill on a low value vehicle.

Hoping someone local ( in Australia ) might see this and have some advice

 

[jrkitching]

I have been quoted $4100 AUD to supply, fit and recalibrate a reconditioned actuator.

That's around £2000, so a bit more than the previous poster in the UK, but not excessively so.

That seems less reasonable - does your vehicle have a DMF? (This would go a long way to explaining the difference)

This illustrates the problem with running an older vehicle; faced with a repair that's maybe 40% of its value, you go ahead - only to be hit with another repair of 50% of its value a few months later.

Sometimes it's best to just let it go, and sell 'as is' when the first big bill rears it head.

This may also help explain why I don't advise anyone to buy a vehicle >8yrs old unless they're capable of maintaining it themselves.

No es necesario, cuanto más limpio, mejor. De todos modos, con el tiempo, se acumulará una película de grasa en la cámara del mecanismo.

norhace falta limpiarlo.

You're right mostly, but I would also be asking 40% of what value?

Meaning, if one is looking for an automatic gear change vehicle, and is willing to fork £1-2k for the car and add £3-5k for things like Selespeed parts (hydraulic or mechanical segment) engine mount changes, shock absorbers, coils maybe, brake rotors/pads, etc wrap it up in some sort of "package" with a proper garage - what may sound like a lost cause may actually be a proper automatic car that cost £5k-7k max, being one that you have a full service status picture.

Realistically speaking, how many automatic - used cars of any brand, made in 2016 (you mentioned 8 years) that cost £5-7k are fully serviced and need absolutely nothing or minimal intervention for the next 20-30k miles? Some exist, sure but they may not have some of the features you want and have more expensive servicing cycles (see VW, Toyota, BMW etc).

That's not to say you shouldn't cut your losses when applicable. - just a different perspective, especially if you have access to a proper garage that can work with you

Hi Folks

I am Rakesh, I am new to this forum as I recently got a used fiat 500L 1.3 Diesel with this robot hydraulic Dualogic selespeed gear box, so adding my worry to this long list hoping somebody would answer my prayers..

Shortly after buying the car, I started to get the "Check transmission" message in the dash and sometimes "start/stop unavailable" or "Gear Unavailable" message.

The car would go into neutral while driving, noticed this mostly when the car is driven in auto mode and when the car is trying to shift up from 2nd to 3rd but goes to neutral instead. This rarely happened when shifting to 2nd gear or while downshifting from 4th to 3rd.
The "Gear Unavailable" usually comes up when trying to drive on the manual mode and when manually shifting up to 4th gear to 5th gear.

I did the scan and below are the error codes

B1081-14 ::: Stop And Start Relay Command - Circuit Short To Ground Or Open Stored BCM (Body Control Module)
P1741-1C ::: Gear Position Sensor - Circuit Voltage Out Of Range Stored TCM (Transmission Control Module)
P2916-07 ::: Fault On Gearbox Subsystem (Unexpected Gear Disengage) - Mechanical Failures Stored TCM (Transmission Control Module)

I checked the transmission fluid, that seems ok. New Battery and outside temp sensor installed and they cleared some other error codes.

What is the ask to the distinguished fellow members:
1. Can I just repair/replace the gear position sensor?

• If yes, what is the OE part number for the gear position sensor for this model (for the 1.3 diesel unit),
• Where is the sensor located, is it in the gear box or in the selespeed hydraulic unit?
• What is the rough cost we are looking at to service (parts+ labour) in the UK or Ireland

2. If the issue is more than gear position sensor, what else could be the potential cause and what needs to be done here? i.e. is replacing the
3. Start / Stop issue connected to the Gear position sensor issue? or are the two separate issues?
4. Can I get a workshop manual (I checked the shorter Italian version already in the download section, translated to English and uploaded it: What I am looking for is the complete manual like the one we have for fiat 500 with around 8000 pages and the error code troubleshooting) and the OE parts list for Fiat 500L 1.3 multijet
5. I checked the Repair thread too, but does anyone have the video or step by step instruction to fix this please to fix this issue once in for all for so many people here and in the open wide world?

Thanks a lot for the help here..

Hi and welcome
Does this repair post help at all?

The one and only Dualogic failure thread | FIAT 500 (2007+)

Unless you know they were using Fiat specific software I’d be reluctant to pull out the gearbox. Find a Dualogic specialist near to you.

After further investigation and diagnosis, the doblo needs a new control module and hydraulic unit.

Not 100% what the hydraulic unit is, however I do know what the control module is.

So far I have had 3 quotes from the same company using parts from a variety of suppliers, starting at 15k, 9.8k and 7.8k - and now he has offered me 1.2k AUD for the vehicle as is for training and R&D

Not sure what R&D they are looking at doing on a 2016 vehicle.

It has been serviced every 10-15k km, so that probably contributes to the good runtime so far.

I am thinking of stripping it and selling as parts, I dont want this to happen again in a year.

Hi guys, wonder if someone can help me.

As a girl that knows very little about cars, my very first car was a Toyota IQ and it was so reliable, unfortunately it got written off by a drunk driver.
A week later I bought a 2010 fiat 500 dualogic. I love those cars and was so happy to have it. A week in, it went into N when I was driving and I panicked…this never happened to me with my fully automatic car! I had to turn it off and on in the middle of the road to get it to move.

This happened about 4 more times over the next two weeks until it got stuck in a car park for 20 mins as would not shift no matter what I did. Sometimes no message, sometimes ‘gear unavailable’

The garage I bought it from-took it to a garage to fix it. They had it 10 days- no loan car- and I haven’t had the report from them yet but was advised they replaced the clutch.

The next day after dropping it back to me it failed again ten mins into the journey.
Then again the next morning. And again when trying to go home after work. Seems to happen more when it’s cold maybe?

This time said ‘check transmission’

I’ve tried to look through these forums but there’s a lot of stuff I don’t understand, a lot of arguing and I just really need some clear cut advice.

Do I need to replace the whole dualogic gearbox to stop this?

What should I advise the garage?
I’ve kept a log of the faults with dates/times and video evidence of some of it- I’m not sure what else I can do.

It also has had “ stop/start unavailable” flashing from the time I collected-is this coincidence/another fault or could it be connected to the gearbox fault?


I’m thinking they might just have to take the car back and give me my money back cos a new gearbox would cost them about 2k and I don’t think they will want to do that….

Any help would be gratefully appreciated cos I’m completely in the dark and worried!

Thanks in advance to anyone who replies xxx

 

[jrkitching]

I’m thinking they might just have to take the car back and give me my money back cos a new gearbox would cost them about 2k and I don’t think they will want to do that….

That is, by far, the best way forward. A 2010 500 dualogic with a major transmission fault is basically just a scrap car, since any repair with a meaningful hope of lasting is going to cost more than it's worth.

I don't think they will want to do that either, but if you've only recently purchased it from a trader, then you have rights.

 

[jackwhoo]

Get your money back

 

[HayleyH]

So I’m this thread someone mentions CD motors being great-specialist in repairing fiats,
I’ve called them and they said they have seen this all the time.
He said it needs a new gearbox actuator. Not a whole new gearbox. He said oil leaks from the actuators into the sensors.
They can recondition mine if it was sent to them however there’s a 6 week wait or they can send out a new one to a garage to fit cost approx 1600 including VAT

It doesn’t sound like the garage it was sent it to understands the issue!

 

[jrkitching]

Forget about trying to get this repaired; just concentrate on returning the car and getting your money back.

 

[rmjbn1]

I agree with the above, it sounds like you should be able to return the car to the vendor for a refund. I would focus my energy on that.

I know it's disappointing when you've set your heart on this car.

Do you need an automatic?

If so, personally I would avoid all robotised manuals like the DuaLogic and make sure I got a genuine torque converter Eg. Suzuki Splash / Ignis.

The manual 1.2 500 is a tough little thing though with a few known foibles.

Hey everyone

I have an update on the doblo.

As a last effort, we found a fiat specialist who had a look at it for me.

The push rod in the slave cylinder was snapped, which is why it couldn’t relearn the clutch position, he said it snapped because an aftermarket clutch was installed which was heavier than the genuine, meaning the push rod wasn’t strong enough.

The mechanic tig welded it and reinforced the pushrod, reprogrammed it and on our merry way, this repair was only $950AUD

Ask for a quote and whether there's guarantee on the repair.

After some days watching the problem i see that message pops up when car is in 2nd gear and wont go to 3d until message disappear. Then it works fine. Same when car is in 2nd and going to 1st.

Also sometimes when i stop and car goes to 1st gear i hear some click click click like car is trying to change gear i think. If i press gas car is moving fine. Also if i move the car 1 meter clicks stops. Check this video for what i say about clicks.
See this video for waht i mean


Can you help please. Thanks in advanced.
