First off I love my Fiat, wouldn't swap it for anything....., seriously.
Even if it is just a 2006 1.4 8v
Up until lately she's been perfect,

Now heres the trouble

About a month ago I started recieving the "radiator temp...." message on the dash upon starting up. And the "EBR Failure" whilst on the M25 I might add. Did a quick read up on here and a new battery fixed this problem. *thanks FF guys :slayer:

4 days ago however this problem returned, but along with it has come the "airbag failure" message and the airbag light constantly on.

Took the car to the garage near my work as i get along with the guys there and had the battery tested,
quote- "your batteries charge is low, but its still ok...."

As for the airbag light, they plugged it into their little diagnostic box, and handed me a LIST of fault codes.....

B0109 - Pass Side Airbag Resist.
B1046 - Windscreen Wiper Switch
U1702 - Electric Steering (NGE)
B1008 - RH Direct Indicators
U1705 - Reciever Radio (NRR)
U1700 - Communic. With Body Computer (NBC)
U1703 - Communication with Instrument Cluster (NQS)

And i was like ...."Wah...?"

And since yesterday everytime i go to start the car, i get nowhere
the dash lights up fine on first click, let all the lights go out and turn again and then the dash just dies and the car doesnt start. It bumps fine, and once the engine is warmed up I can restart the car fine.

Been looking around the Forum and was wondering if i was right in thinking these were my next steps to take.... before i go shelling out on garage costs and replacement Alternators or starters....

1...fully charge battery, or replace with a stronger one
2...contact FIAT to check or arrange software update for Airbag system *Recall
3...Proxy Alignment
4...Have faith it works

I'm not the most clued up guy when it comes to engines and electrics, i prefer the styling side, hense why i only bought a 1.4 8v

Anyway, any help would be VERY much appreciated, even if its just a point in the right direction, As the MoT is looming closer and closer.

*sidenote.... thats a lot to read, I appreciate your time, I havent wrote this much in a loooong time...

First thing I would try is attach a jump lead to the - pole of the battery then to the engine block and try starting if no help then to the car body if the car works ok it could be a weak or failing earth cable (see our guide section I have listed the basic earth points in the engine bay

Since my laptop is still turned on (was on my mobile when i replied ^) take a look here https://www.fiatforum.com/grande-punto-guides/169204-grande-punto-engine-bay-earthing-points.html

I've had every problem you've listed, happen to me about two weeks ago. Car wouldn't start and dials were bouncing when I tried starting the engine.
I started with using ELM software trying to work the problem, but quickly realised the battery was dead. So replaced the battery and tried again, most of the warnings went away bar the battery light. It started but the radio was cutting out and coming back on, also the power steering went heavy after 30 seconds of driving.

Spoke to a close friend of mine who works at a fiat dealership, he suggested it would be the alternator. To check the alternator, we can check the voltage of the battery (using a multimeter). Without ignition the battery should be around 12.5 volts give or take, If your battery isn't reaching this figures give it a long charge or look at getting a new/borrow a battery. When the ignition is on the voltage should be higher (around 13.5/14 volts). Mine was down at 8 volts.

This then confirmed my worst nightmare, the alternator wasn't working.This meant the need of a new alternator. Cost me little over £300 through a little garage, but quotes varied from £300 to £450 including part, fitting and VAT.

Hope this helps with the diagnosis.

@AndyMonty, I shall check them all today, thanks for the suggestion...

@Berty10, the battery runs fine in that sense so it's not an alternator swap, I couldn't manage forking out that much either, but cheers for your insight...

Okay, so the car started fine this morning, bar the airbag warning,....
Thinking maybe the battery had a bit of charge in it from a late drive last night.

Anyways, been and done the Earthing points and shall see how she goes on that front.

Can't seem to get through to my local Fiat dealer, would it be fine do you think, to just drop by.... ?

Okay, flat again this morning, evidently not the earthing points, but at least that's one thing checked. Would a new starter motor help ?.....
