Another thing I was told (on Thursday when I collected my "fixed" car) was that if S&S did fail then I would need to drive 40 miles, leave the car 4 hours, then drive for another 10 miles and only then when the car was restarted would S&S work!!! Apparently it reboots the system or something.

Sounds like they talking about the Intelligent Battery Sensor which has to run through a calibration whenever the battery is disconnected, as I've already said- ;)

Once fitted, the IBS monitors the battery condition (voltage capacity, drop, etc) over the next 5 starts with a gap of at least 8 hours between them to determine the battery's ability to perform the repeated stop/start operations. If it's starting from a weak first-charge, you'll have system problems.

...though to be honest, the calibration procedure should only cause a real problem (ie, no S/S) on the first run after the battery is reconnected. Once it's gone through it's first start-up, drive, park-up, leave for 8 hours cycle it should start operating normally, and be fine after the 5th cycle.

So, do you think it was just a case of running the new software update in for a few days?
 
For those not yet had the software update, I think we've found a kind of workaround for the issue. We've only tried it for 2 days, but it's had 100% success rate so far...

We've had the lights come on when reversing off the driveway every morning. For the last couple of days, we did the following procedure:

1. Start ignition
2. Hold down the start'n'stop button to manually deactivated the s'n's
3. Reverse off the driveway as per normal
4. Hold down the s'n's button again, to manually reactivate the s'n's

And that's it! Not a solution as such, but it seems to have gotten around the problem, so far!

I think what's perhaps going on is because we've deactivated the s'n's manually, it never gets a chance to deactivate it automatically, and it seems to be the automatic deactivation that makes things go pear shaped.

Mind you, we haven't yet tried NOT doing the workaround since we found it, so maybe it's just fixed itself!
 
Thanks for the welcome. Warning lights still coming on. Contacting Fiat again tomorrow. Feeling really depressed by it all. Just wish they would take it back.

we will see!

They have to fix it pretty soon or you can reject the car presumably. Very annoying I can imagine, but don't feel down, its only a car... once its fixed we will all be envious (me especially).

To all those who are booking their cars in- Please ensure you demonstrate to the Tech how you get the fault. This way they have a definitive method of reproducing the fault and therefore can be confident that when they are done it is cured. ;)

There's nothing more fustrating to a Tech than a customer saying a fault occurs all the time, not demo'ing it to anyone, then the Tech doing endless checks and roadtests without success because they can't replicate the exact conditions because they haven't been shown. :bang:

(Of course there's nothing more amusing than a customer complaining of a fault, and how "the Tech's can never fault it, blah, blah"- then are unable to recreate it themselves on roadtest :cry:. Finally they realise and understand what a difficult and unrewarding the job is as a Tech.)

i think the problem comes from the fact my service receptionist is not knowledgeable, i never get to speak to the tech, i have left precise descriptions on whatg causes the issue (or issues as there is more than one!), im told they are fixed, and clearly they are not!

ie my squeeky brakes...twice i told them what conditions cause this, ie slow pull ups, light braking etc...twice im told they are fixed, twice i get the car back and twice it happens straight away....



so i will have to take the tech out for a test drive next methinks
 
i never get to speak to the tech,

then demand too! When you phone BT to complain how crap they are do you really want to speak to a call centre person about a technical fault...NO you want to speak to the technical department.

Service reception has bookings to make, phones to answer, invoices to make up, filing & other jobs so IMO they are the last person you want to speak to especially on a busy morning. Talk to the tech (or DET as thats their job so Fiat say) or take your car elsehere.

Leaving notes unfortunally rarely works as they fall out pf job cards & get binned:(

Scratch that, doesn't always work :( Tried it yesterday, and bad lights still came on.

Strange, as they didn't come on for a couple of days, and not sure how those days were different from any other.
