General 105 Twinair Cold Starting and stalling issue

I had everything turned off on start up ,Radio,Air-con etc but still it persisted in colder temperatures only hence why i thought it must be a sensor ,aschen needs to do the same turn everything off ,

It could be a sensor, but my money is still on oil viscosity - when temperatures drop to freezing levels, friction from even an 0W oil will increase significantly; and that's before we start talking about the effect of the higher viscosity oil on the hydraulic valvegear.

I wonder how much additional testing Fiat did on the 105TA in subzero temperatures?

Not a problem today, thankfully - it's a most pleasing 21C this afternoon in Bournemouth :)

Yes as a process of elimination I think I would push to have engine temp sensor replaced, also do an oil change with selenia 0w30 and perhaps reload software to ecu, getting your dealer to do all this is another matter though! Frustratingly you probably won't know the results until next November!
 
Note, when starting the AC compressor is not engaged, though the fans may run(in older systems), the system waits for about 5-10 seconds before activating the AC clutch.
I always leave it on(AC) and have never had an issue though this was not with a 500, but I wait at run position for some of the dash lights to go out, then crank.

Lol yes this is why i believe its got to be a sensor whether the fault shows up or not ,as you can see from both our videoes the mileage on yours and mine were below 5000 miles the temperature is always the problem if left outside overnight and its below 5c it did not start first time 6 out of 10 times sometimes more .It must mainly affect the 105 mainly i loved the little thing but after 2 dealerships had the car for a combined total of over 2 weeks and both said there is nothing we can do the fault does not repilicate etc no faults on the computer or im fibbing which i knew i wasnt i bit the bullet and sold her !,i even sent the video to Fiat hq via a customer services agent ,maybe they are now realising there is actually a problem which is great for you i hope .(y)
P.S i did not use the air con on start up .

I would agree with you as well, it does seem to be some sort of temperature-related sensor issue. What that issue may be is anyone's guess, but that would seem to figure with the car firing up and then gradually dropping the revs until it dies. Almost seems like it is starved of fuel, maybe because of a difference between the actual air temperature and what the ECU/sensor in question thinks it is? I wish I knew!

There is an intriguing thread on the Panda 2012 section with a guy in Australia who has a 1.2; when doing the first cold start it will fart its way into life and then run like an utter bag of spanners. However, turn it off and restart it and it works just like normal; just see the video:

Post 24 on that thread from series2a may just possibly be of use here though as an alternative suggestion?

What I find particularly sad from your story here is that you in particular have been treated disgracefully (knowing from your time on here that you have had LOADS of Fiats:)). I mean this in the nicest possible way, but you must be mad to get an Abarth and stick with a Fiat Group brand :cool:

Funnily enough a few times when the car has been in to be fixed they give us an Abarth 595 Turismo, that works perfectly fine and never had an issue, they have given us a 1.2 before and that's fine (not quite as fun to drive)

When it's really cold (well below freezing) It doesn't even need a load on the engine to stall. If it is a sensor Fiat have had several opportunities to fix it and i'm not sure if it's first service included an oil change but still Fiat have had the opportunities.

I did wonder if they could take it to a cold test facility (we live right by Mira on the A5 in the midlands) they have that type of facility there, i'd take it myself but i'm pretty sure it'll be massively expensive. I think it would be cheaper to drive the car somewhere cold.

We're waiting for responses from Fiat so hopefully can post an update!

The Abarth has been a pleasure so far and very rare in my area and yes i must be mad but really enjoy Italian cars ,usually when looked after etc they are pretty much trouble free but the newer these cars are getting the tech is even more sophisticated and more things to go wrong but then that`s the same with every brand out there now .
 
So it appears my new car has been ordered as a 105hp - should I be worried?:confused:

I've asked for it to be changed on the system but the guy seems to think that can't be done (order not yet fixed as far as I can tell)...

It wouldn't bother me, if I was buying a new TA now I'd be ordering the 105. It's a very small percentage I'm sure that have issues, probably not any more then the 85 in reality or the 1.2 for that matter. The 105 was around for a while in the 500L so it's not a 'new' engine. Anyway you always have your warranty to fall back on.

Fiat (Dealership) Made an error with our car, and managed to change it... As for if you should be ordering one, chances of it having a problem are low, just because a few have an issue doesn't mean you will, however I guess we didn't find out the issue until it was winter and cold. Any issue will be covered under warranty as someone else has stated. I wouldn't have another twin air but that's due to poor experiences in dealing with the issues the car has had in 18 months (not just relating to the cold start issue) You are in the same area as us too, I wonder if it is the same dealership.
 
Well after 14 months of telling Fiat that something isn't quite right with the car, and subsequently going down the route of rejecting the vehicle (as the fault was reported before the car was 6 months old) it's gone back to Fiat.

It didn't go as far as mediation as the dealership, Fiat and the finance company decided to work with us to get us into another car (not a TA) as a solution.

As the 1.2 liter was a little on the slow side when we had them as a courtesy car we swapped into 595 Abarth Trofeo special edition Tricolore.

You have quite a lot of rights when you buy a new car (as I found out during this) Lets just hope they don't sell the old 105 TA and give someone else the problem.
