Help coding in larger capacity battery near south Manchester (Stretford)?

[Gunship]

Afternoon all - this cold weather has convinced me that it's time to change the battery on our T6. I'd like to replace it with a larger capacity battery as we have a camper conversion and I understand that there are few bits that take from the starter battery, which has been evident on trips where we haven't moved the van for a few days, and it hasn't been the happiest when asked to start, so I think we're a bit too close to the limit on a 70Ah, so I think we'd be happier on a 95Ah.

The barrier for us is the coding element - I don't have the kit or the knowledge, so looking for any hive mind recommendations of recommended places as near to us in Stretford (south Manc) as possible. I'm assuming (but I don't know) that this job isn't the sort of thing any garage would be able to do for us?

TIA.

I can do this for you if you're ever near the jnc23 of the M6 (it's where the east lancs goes under the M6 bridge, called Haydock island) if nobody closer to you offers to help. Only takes a few minutes and I'll scan for any fault codes as well if you want why it's plugged in.

That might actually be really handy - I work 1 day a month in Woolston, sometimes 2/month and usually get away for about half 2, 3pm. That's invariably on a Tuesday. If that wouldn't put you out, I'd be extremely grateful and take you up and that very kind offer.

 

[Howzat]

Yeah, that could work. DM me when you next plan to come across.

Hi Gunship, Matter of interest, what battery are you fitting and where are you getting it from? My original 2016 VWT6 battery needs replacing.

That I haven't worked out yet but I think this is the thread to use for guidance (Dellmassive is the man with the plan in there) Upgrading Starter Battery - how to guide

Yeah, that could work. DM me when you next plan to come across.

Thank you very much! I'll try and work that out ASAP.

So have a got this right
If you get a flat battery, you can’t just buy a new one and fit it yourself because it needs coding?

 

[Howzat]

No. Apprently it wont fully charge if the BCM thinks its a lower capacity but I believe it will rectify itself after a few drives.
By coding the new battery you ensure it will charge properly from the off.
This only applies if you buy a bigger battery than the 75ah OEM version. Buy the same size battery and coding isn't really required.

Right I get it now!, thanks!

As well as the capacity setting you would normally update the serial number (doesn't matter to just that it's different from what was there.

That's because the BCM tracks the health of the battery as it ages and reduces capacity, and changing the serial resets this.

The BCM should self learn in about 10 charge cycles, but it will under charge to start with in the belief it's still your old battery.

If you're changing like for like little need to code unless you can or you are working your battery very hard, if you're changing capacity as well I'd try and get the coding done.

Morning Howzat. I've just found out it will be February now, probably the 11th - a long way off (sort of). That's fine for me because it means I bank another pay day before having to buy a new battery (I assume I come to you with the new battery in the van, which seems to make sense).
