Battery drain issue on 1.4SC Ibiza

Well that SEAT dealership that I handed that late 2009 Ibiza 1.4 16V SC into had just dealt with a same age Polo 1.4 16V, so VW dealerships will also know about this, but probably as I said, most of this was an issue roughly 10 years ago.

That SEAT dealership was Arnold Clark and they had/have VW dealerships elsewhere in Central Scotland, so I'm not sure if they would have used maybe its VW diagnostics license to source or locate the BCM S/W update.

You can only ask, but take some "facts" - remember in most garage's mind, internet forum chat is just that, ie wrong and hot air, so be prepared for that logic to be used into your face.

Good luck as getting this sorted out removes the uncertainty of "will it start?".

Bump!

I am having / had this issue for a while now! If I leave my car for around 4 days the battery is dead.
I have had a new battery installed by RAC almost 2 years ago they did various tests that showed no drains and a new alternator fitted in Jan. Each time i thought this would solve my starting woes.

I'd think that probably the only way to dismiss it being a BCM needing an update, will be to hand it into a SEAT dealership and direct them to look for tech help from SEAT mothership if they have never heard about this, also give them the SEAT reference number for this patch/update - "J519 module, ie BCM or Central Electrics, that update/patch was 30EB or 30eb . "

I'm guessing that your Ibiza is a 2008 or 2009 build car?

Yeah its a 58 plate. I will give Seat a call and see what they say.
Also to add this morning was first time I have driven since the last time my battery died (sunday) my electric wing mirrors have a mind of there own, could that be a separate and coincidental issue?

I'd think coincidence or due to low battery voltage.

Edit:- remember to spoon feed your SEAT service desk with all the info you have collected in this forum, many/most workshops treat all internet chatter as being just that, ie complete load of BS, and most of the time who could blame them, but sometimes, just sometimes, there are some true facts out there covering some very strange or rare issues, and I think that this, if it is a BCM patch/update issue, is one of them. I'd expect that you will need to pay for 1 hour diagnostic testing by a master tech - which will probably be nothing more than a quick full scan of the car's controllers for logged faults, after that if all goes well I'd either expect them to be able to locate where to find this patch on their online system, or log a "tech help" report to SEAT mothership and that should end up with them being directed to the patch/update within a couple of working days. After that it should only be a case of re-booking the car in for them to apply this patch/update and that should not cost any more than 0.75 hour labour, the actual patch/update will be free - which is correct as it was a mess up by a SEAT supplier.
I still can't explain why this only turned up on my car and some others as late on in its life if it really is a S/W issue - but there you are! I think that SEAT and their dealerships workshops will have expected all the affected cars to have been fixed during the warranty period, which might add to the confusion of why this has been happening later down the line.

Thank you.
Yeah i will more than likely say RAC told me X Y Z and have a report from them looking into battery issues on my car (have had them out twice) and that it points towards a SW patch.

Good advice as always! In the end though I didn't go to Seat Dealer because my nearest one is now so far away in the next county. Plus I hate going to main dealers thinking they will be charging an arm and a leg.

I have though brought a small battery jump start-on the occasions when I needed it, once during the last12 months, it was easy and quick to use.
