Peugeot 3008: prob electrical fault? Help!!

[JJ_2319]

Hi people in my phone.
Long time viewer and now in need.

2013 3008 1.6 HDi.
A week ago, I climbed in and tried to turn engine over. Just clicked. Jumped the battery and all was fine.
Similar earlier this week so replaced battery yesterday (after running multi meter across showing little voltage). Car started. I did a motorway run with no prob. On my return home, after engine off for two hours, had 3 warning lights on motorway (amber engine fault, amber handbrake warning and, I believe briefly, a red light). Lost power and coasted too hard shoulder.
AA, came to check, initially was convinced it was alternator. Sometimes car tried to turn over but wouldn’t, on further try may have clicked or didn’t click. Seemed very variable. Difficult to really unpack from the guy as he wasn’t really in the mood to do much!
He did eventually plug in the diagnostics to have a look. On two occasions the car kicked him out. Eventually it let it run but took an awfully long time to get anywhere and so he stopped it at a point that he had identified the codes in the image attached.
I do know I have the warning light for Eolys on and I need to do this.
the AA guy, after he got bored, put it down to electrical gremlins and said could be abs/ECU and I need to get an auto electrician to have a look.
Attached, I screenshot the codes that he had pulled up. Quite lost on this at the minute so within this forum if anyone has any ideas at all, I would really appreciate any help. If anyone is to the east side of Leeds??!!!

Thanks in advance for anything you might be able to do or suggest that I do.

I would start with a BSI reset, you might have upset the system with flat battery and changing it. they need the correct disconnect and reconnect procedure.
Then have it scanned with Diagbox , Clear any codes, some me be old / historic. Then rescan
If you report your findings back here, there is a wealth of knowledge on this forum and someone may be able to point you in right direction

Hi steve

Thanks for your help.
Is there a foolproof guide proof proof guide for this?
Do I need any specific kit/diag tools?

Cheers

No special tools or equipment needed. Completely zero cost.

When you have done the reset, Try the car. If still having problems, Check for any members in your area that could scan it for you With the correct tool

[JJ_2319]

Thanks for the input guys.
Did a BSI reset as you posted, Paul, with thanks.
Turned everything off, boot torch, interior lights, disconnected dash cam etc.
it worked and car started!!!! Plugged a basic code reader in that said I needed to run with ignition on but engine off. Did this, no faults identified. When I tried to turn over engine again it turned over, got to 1000revs and died away. Tried again but only got to clicks of electrics, no engine trying to turn over at all.
Any thoughts?
How do I find someone near to Wetherby (LS22) that might be able run a diagnostic?
Thanks all.

It sounds like you have battery gremlins to me!! This is the list of members with diagnostics and willingness to assist. Read the initial paragraphs to know how to use it best!!

Thanks Mick. Sadly not many local to me. Surprised none in Leeds or York.
Will have a look at other options.

Check the battery voltage to see if it is battery related. Should be 12.7 volts if fully charged before the first start of the day and with the engine running about 14 volts unless it has a smart alternator which could then be lower at 12 to 14 volts depending on the battery state of charge. If you do not have a voltmeter they can be bought for about £10. As an example for £8.50 from Halfords https://www.halfords.com/tools/hand-too ... YwJGwwJGgw

Does the dash cam stay live all the time since this could be causing the battery to go flat ?

[JJ_2319]

Thanks Paul. It had a new one installed on Friday.
AA guy rocked up on Friday and initially said ‘alternator’. Then he blamed electrical gremlins.

[PaulC5]

You still need to check the new battery voltage in case something is causing it to go flat.

Hi guys.
Thanks if you’ve managed to provide advice and help.
Had time after school to search around.
I managed to do a fuller scan than it seemed the AA guy did. It threw up two codes:
U1308
U1108

These codes remained after I did another full BSI reset, turned the engine over (didn’t start, see clip) and rescanned.

Others but nothing massive and not linked.
I’ve also attached a short clip of turning over.
After
Identifying fuses and relays, could it be a corroded main ECU relay? They seem in tricky locations hidden in front of the main engine fuse box.

As always, any help appreciated!

Are you using a fully equipped lexia/diagbox to read those codes? If not it will be extremely hard to find the fault. Cheap code readers can work on some simple problems, like my 14 yr old daughter, doesn't mean it'll give accurate answers to problems.
