147 EBD System Failure - Help please!!!!

Hi All,

My 52 plate 147 has run like a dream for about 12,000 miles. Had it serviced last Friday, plugs, suspension arm etc. All fine.

Then this morning I tried to start her up - NOTHING! just a click.

A neigbour helped with a jumpstart, got her running, moved about 20ft and then EBD system failure comes up and she dies again.

Another jump start, died before I could even close the bonnet.

The third jump I got her going, kept the revs up, let her idle for 10 mins, then drove 50 motorway miles, all fine. Until I parked up, nothing again!! Totally dead . . . !

So, my best guess is the battery is dead? But would a battery just die so completely overnight? Does this sound normal?

Also, the main dealer wants to put it on the diagnostic rig () and try a new battery?

However, drawing on the experience of the forum . . . would I be better going to Halfrauds and just popping a new battery in myself?

Any thoughts, advice or assistance would be massively appreciated. I'm at work now, but at about 5pm I'm gonna have a massive problem on my hands - unless I get a battery at lunch.


The illusion of freedom will be maintained for as long as it's profitable to do so.

Your battery is obviously dead. The other errors like ABS/ASR/EBD faulire are secondary and will go away when you replace it. And yes, 147 batteries are notorious for dying overnight without any previous symptoms apart maybe from frequent lightbulb failures due to power spikes in the car's electrical system as the battery fades away.

Batteries can just die, but it's rare.
Can you just nip to the local motor factors for them to check out your battery/ charging system first?

Do you know how to check the voltage of the battery and the charging system?

OR join the AA or RAC and they can diagnose it for you.

If you do get a battery get a good powerful one!

Check the water levels in the battery, top it up and recharge.
Worked on mine. Keep the money in the bank as long as possible!!

Despite what my local independant told me . . .

The battery appears to have died overnight. RAC man drop tested it and put an ammeter tap across it.

The lights AND aircon were enough to drop it sufficently low enough.

£100 new batt, 3 year warranty. A little steep I grant you - probably could have got an Alfa genuine for that.

But, car dead - miles from home - £100 is a small price to pay.

Re: 147 EBD System Failure - Help please!!!!

Mine died overnight exactly 3 years after I had bought the car.
Symptoms were "ABS/EBD Failures" a couple of months before the incident and suddenly one morning only it just wouldn't start up.
Headlights and aircondition were working but as soon as I turned the key there was a blackout!
Battery was of the "compact" type which you can not do anything.

Mine does it all the time but we realized its due the positive ring around the battery some how the screws keeping it together had come loose so the ring would jump off a little whenever I went over bumps would continue running fine until engine is turned off. I was having to push it back on fully and it would start but after tightening the screws, it's totally bk as it should and doesn't jump off so try it you never know!
