The main problem is crawling in traffic on hills - that’s what tends to finish off the clutches in Ferraris and Lamborghinis, and FIAT’s Dualogic is no different. To avoid riding the clutch, you have to hold the car on the brake (I use my left foot for this), and when you move off, you have to do it purposefully so that the clutch engages completely. This probably means waiting for a gap to open in front, rather than moving forward at walking pace which will slip the clutch almost continuously.

Very sad to see our Fiat 500L go as we loved it. But lost all faith in it and Fiat!
I agree that it is very disappointing that there was no explanation provided or any goodwill by FIAT. At least after all that time in the workshop, it sounds like you were able to sell remarkably quickly.

The hill start option does this for you.
Yes I get that from a technical point of view.... but what about the legal point of view if you take them to court! You buy an automatic car and the gearbox clutch arrangement fails early and within warranty. How can they justify that in court, when its controlled by the car! I would be taking them to the small claims court!

Lol - and thatís probably why the Dualogic is not available in the USA. Quite simply, itís not an Ďautomatic carí.

I think Fiat were clever here, as all of the other manufactures have had issues with the robotic clutches and the US market where creep is expected on an automatic. Smart had major warranty issues as you can imagine, when they set the robotic gearbox ECU to mimic creep by slipping the clutch!
These gearboxes are designed for the EU market where emissions and fuel economy is everything. In the US, this isnít an issue as naturally any 1.4 litre car is going to be economical LOL

Hi guys!
Newbie here. I know it's been asked loads of times before but I'd really appreciate some help for my car in particular to show the mechanics...
Bought a 13 plate 500 Dualogic the weekend before last with only 6000 miles. It was fine Sunday-thursday but on Friday it cut out (more below) so I took it back to be sorted. Received it back yesterday and today it's done the same. When I've been braking it cuts into neutral, can't get it into gear with the gearstick and have to repeatedly turn it on and off again until it starts.
1st time- 60mph to a stop for a roundabout when it cuts out
2nd- 30mph to a stop for a roundabout
3rd- (travelling to mechanics) doesn't cut out but coolant warning light comes on as I pull up to roundabout, however actual gauge doesn't change level
4th- (day after I get it back) doesn't cut but coolant warning light and seatbelt light both come on
5th- coolant light comes on, car beeps as if it's about to hit neutral but I manage to get it into 1st manually before it cuts out.

Strangely, the most I've had on a 45 minute drive to the place I bought it is the coolant light, it cuts out on 10 minute drives to work. When you open the door you hear it whirring (technical language right here) for about 8 seconds which I've read is far too long. Mechanics couldn't find a fault so just did a gear selection calibration. We've checked oil and coolant levels which are fine.

Any ideas would be hugely appreciated, and please do ask if you need more info! Thank you

Re: Gear box oil

The only real way forward with any dualogic gearbox fault is to get any fault codes read using a specialist code reader that's suitable for this purpose. If you have a windows laptop (an old one will suffice), then Multiecuscan can do this for the price of a cable or two and a €50 licence fee. If you let us know approximately where you're located, then someone near you who already has the diagnostics may be able to help.

What's the engine type and approximate mileage of your car?

Quite a few of the reported failures have occured at that sort of mileage. How long has she owned the car?

I would not have thought it likely.

She's had the car a couple of years I thought Mabey a new filter and a gear oil Change may help

Unlikely, I'm sorry to say.

I'd suggest you read carefully through at least the first couple of pages of this thread.

Correct identification of the cause of the problem and replacement of any modules found to be faulty is generally the only hope of a lasting fix; sadly this course of action is unlikely to be cheap.

The car is in Scotland as my daughter is at uni there and I'm in Kent is there anyone on the forum with a code reader near to Falkirk or Stirling that could possibly read the codes for her or anyone with knowledge of a decent independent with fiat code reader cheers from a miles away dad to a daughter who hasn't got a clue around car mechanics

Why would you be asking someone from a forum to go help your daughter??


http://www.jmmotorengineers.org.uk/about-us - is listed as an Alfa Specalist in the direct area on the Alfa forums

Or

http://www.mclennansgarage.com/

I tend to find that Alfa guys have the most experience with the Selespeed gearbox units - either garages do Fiats

If you have bought this from a reputable car dealer, you should be able to reject it and find something else.
I would guess too much prep on the dealers side (steam cleaning and spraying the engine bay with water) hasnīt helped the electrics / ECU ... either that or this was the reason the previous person sold the car in the first place!

These cars are generally reliable
