Hi Did you manage to fix the issue? I am having the same problem, engine cuts out when car is going slowly around a roundabout and cannot be turned back on

105S said:

My wife's car (105 TA) has just had it's first service (4.5K miles) I noticed in the last month or so when the engine was stone cold it would cut out and was a right sod to start up again (the cars always in 'sport' mode with the stop/start always switched off). Luckily it never happened to my missus because I don't think she would have got it started and on some occasions it happened in dangerous/embarrassing circumstances. When it went in for the service i told them about it and when we went to pick up the car they reckon the electrodes on both spark plugs were badly burn out. Being a consumable item? they charged for the plugs and fitting too. She tends to use super unleaded so they blamed the spark plug problem on that

Two things. Firstly we have a 105 TA and I ran it on super unleaded for a while when new and we were having lots of engine problems with it. I changed to regular unleaded and it immediately ran much much better so we learned a lesson there.

Secondly, the problems I mentioned above were engine light and limp mode kept happening intermittently in the first 1000 miles from new. Got into an almighty row with FCA and Ancaster over it and ended up getting £1500 refund off them. The problem turned out to be the electronic throttle pedal. They replaced it and it's been problem free since.

The moral of the story is that the engine is very complicated and any electrical component that fails causes the car to immediately go belly up.

You could try getting an fault code reader and plugging it in when it stalls so you can get the code when the problem is live. Then give that info to your Fiat technician at the dealer.

Me too.
2012 Fiat 500 Twinair misfiring

I know there have been some other threads about this but some seem quite dated. Firstly, I know nothing about cars. Two mechanics have looked at it with no fix. Car is usually (not always) ok at modest speeds 80Kms. On a Freeway doing 110 kms per hour I get random misfires. Three or four in a 30 minutes journey. When I stop and turn off the engine, then I re-start it is ok until next time.
Error Codes
P0301 Cyclinder 1 Misfire
P0300 Random/Multiple Cylinder Misfire
P1120 Throttle Valve Position Control
P1220 Accelerator Pedal Potent. (Feasibility)

Coils have been replaced
Spark plugs have been replaced
Engine flushed and new oil put in
Throttle body cleaned
Decarbed engine and intake

I have read about ECU being a problem? Should I replace it? Help!

Hi all, Reviving and older thread looking for a little more info.

I have a 2021 (71 plate) Panda 4x4 twinair 85bhp. It's at 8500 miles and it has started to cut out.

So far it has only been within 300 meters of a cold start. There are no lights, noises or indication any thing is wrong before it cuts out. The last time I pulled up to a junction with the start & stop system off, whilst taking it for a service. The engine dies and you get a polite notice saying the start & stop system failed.

Here is the fun part. It then wont restart. We even tried to jump start and nothing.

Eventually it starts, each time after the computer have been access via the OBD port. But it can take 15 seconds of turn over before the engine catches. You then need throttle it for it to catch properly.

After it restarts you can turn the engine off and it is as if nothing went wrong, starts immediately and back to the old smooth driving.

Again, no dash lights, warnings or error codes. Being only 8 months old I have the dealer intrigued but they can't find a fault (as I got it going) unless they can experience the problem. I have a curtesy car and they are going to try and re-create the problem over the next few days.

Fiat recovery have helped once and the engineer was also perplexed, it may have been low on oil as it was due a service, but no oil warning lights.

If anyone has can advise if they have experienced the same and had a fix that would be great.

Many Thanks

Hi
Have you driven the majority of those 8.5 thousand miles?

How long has this been happening?

We have an OLD twinair that does weird things like this..

As usual.. these threads dont get an answer very often :-(

Hi,

All 8500 miles, and it started last week, twice.

It's a long shot on an answer and if I ever get to the bottom of it I will reply.

Thanks

I too am glad is fixed and hope you stick with it. My expereince of Pandas is growing and all the ones we have had have been better than averagely reliable. We have now had at totla of 12 Fiats in the family over many years and my own have totalled about 275000 miles. The only really annoying failure has bee the evapouration cannister and solenoid that were done on our 2014 car, by the dealer at a cost of £650 in total. My company car were no more reliable and I have to say a lot less economical than my Fiats. My Panda 100 did 100,000 miles faultelssly and my Bravo did 100,000 and was replaced as the gearbox was making ominous noises. It does take quite awhile to forget and forgive when a car lets you down badly like this, but in this case I hope youn persist as the small Fiats are a joy to drive and own. Your problem identified is a valuable contribution to the experience and knowledge base on here, so thanks for reporting the problem and the solution. I hope the experience improves dramtically from now on. PS Welcome to the Fiat Forum.

Hi all, I promised an update so here it is.

As suspected the 0.9 twinair 85bhp is a fussy little sod.

It was 500 miles from its first service. After the service and a fresh set of oil, everything has been fine for about 10 days so far, so the general consensus was it was just low on oil and the ECU had a fit.

2 things that didn't help. The dipstick is a gold colour so it is hard to read the oil level (with clean oil), and there were never any warnings about oil level or pressure.

Therefore, every 5000 miles I think I will give it a top up, with the very specific oil it needs.

Does anyone know a good store that sell the specific oil ?

Fingers crossed that solves the problem permenatly.

Scott

Hi

I lay the dipstick on kitchen towel

The oil line is then evident


My TAs dont use oil.. but hopefully that is your problem

( blindly adding oil will prove expensive!!)
