Technical Fiat Punto 2014 1.4 dualogic

[Imense]

Hi guyz , new member from Melbourne Australia here .
I have 2014 Fiat Punto 1.4 dualogic and it’s not downshifting 4 out of 10 times for which I have to turn of the car in the middle of the road and restart to make it go in first gear .
Also it seem like high rpm if I go on freeway with 100km cruise set .
plz see attached picture of speedo
3300rpm on 100km cruise set .
Is it high rpm or normal for a 1.4non turbo ?.
Is my clutch worn out
I have screenshot from one scanner related to clutch .
Plz advise .
Thanx

Fuel economy is not good 6.5L/100km .
Rpm 3300 @100km .
Either clutch plate slipping or clutch not fully depressed.
I need ur guyz opinion .

Hi

The 1.4 in a grande always had a reputation for drinking fuel


100kmh : 75/80 mph

My conventional FIATs both do 3,000 rpm at 70 mph.. so yours sounds reasonable


Downshifts.. different issue read the GUIDES for info on the system and its needs

Sounds like you have not owned this car for long??

Thanx for reply varesecrazy
62mph =100kmh . And yes I haven’t owned this car for long .
My 2005 honda civic 1.3 stays on 2000 rpm @ 100kmh .

I think 3300rpm is high for 60mph or 100kmh

Previously I had an 2006 punto dualogic diesel it's sit below 2000rpm#100km .
I understand petrol is high rpm engine but still 3300rpm @60mph or 100kmh seems high

Anyone with 1.4 and dual logic can confirm rpm range ?.

Its a rare car now in the UK

BUT the gearbox wont be much diffetent to a conventional 5 speed Manual

( yes the Diesel probably revs lower)

With a Manual you can obviously lift off the throttle at a steady 100k/ 62mph and revs and speed will SLOWLY fall..

Really the dualogic should do that too..

If the revs tumble..but speed doesnt ..
then a clutch issue is possible

Engine noise on freeway at 62mph/100kmh feels like its revving high waiting for next gear to engage .

 

[Imense]

Foot off accelerator with cruise set 100kmh with 5th gear , rpm not dropping below 3100rpm no matter uphill or downhill.
All my other cars @100kmh are near 2000rpm or below .
If Somebody with 1 4 dualogic can confirm rpm with there speeds .

Dualogic is just an automated gear selector.
Gearbox is still regular C514.5, MANUAL.
You could swap the selector for normal one (manual version), convert the car (in theory - electronics is the problem, not mechanics).
Speeds are OK for real manual (example: gear 5, speed 110 km/h = 3500 RPM). Yes, it's a bit "high", but that's normal.
That's why there are C514.6 versions with 6th gear (and this is the one for highways, 5-gear version is more for city use).

Search Google for "fiat dualogic".
Also YouTube (there are videos - clutch swap, selector teardown, repair etc.)!
Search for basic maintenance info (it's hydraulic right? - there is oil, maybe you should change/add some)...

Your fuel consumption is actually GOOD (about 6-7 L per 100 km). You have no clue (expectations are too high). Newbie to the Fiats?
Grande/EVO (whatever) engines, are based on old FIRE family, from 1980's! C-series gearboxes too.
Don't expect too much (economy, smooth operation etc.). Don't compare to modern cars (especially turbo diesels with 6-speed or more gearboxes).

So..

Whose 'automatic kit' is on this?

last I drove one it was the same French built gearboxes..originally developed by Ford and FIAT

I think you are comparing apples to oranges here.. ;-)

I m not disrespecting fiat , I am just asking if this is normal for dualogic 1.4 punto ?.
Because too me its seems like restrictive.
