CHANGING THE BATTERY ON A 2016 T6

[Jensenmike]

Hi everyone,

I've just purchased a 2016 T6 Highline 150bhp BMT van. I'm assuming as the engine is Euro 6, it has the stop start capability ? However, if it has, it appears to have been permanently disabled, which doesn't bother me. I need to change the existing battery which is a Yuasa EFB YBX7096, as it appears to be knackered & am thinking of replacing it with an AGM of the same size & capacity. Changing the battery myself isn't a problem, but am I right in thinking that the change needs to be programmed into the VCOM ?? if so, it probably needed to be done by someone with the ability to do this ?

Please excuse my ignorance, I've been driving a T4 for the last 22 years & the electronics have advanced somewhat !! Any advice appreciated.

There is a function to programme the battery in VCDS, but in all the cars I have owned with stop start I have never noticed any difference after programming. I replaced the one on my T6 a few weeks ago and I did input the manufacturer and capacity.

My stop start also appears permanently disabled.

Many thanks for your reply Vedubber. So probably if I fit a new battery without programming it in, it isn't going to do any significant harm to the new battery ? I've got a multimeter which I use often, so I can check the state of charge I guess.

I'm wondering if i should buy a VCDS scanner tool ? although I seem to remember someone warning me to be careful what I buy, as some of them will come up with all sorts of erroneous error codes ?? I'm not sure what would be the best one to get ?

 

[Vedubber]

no it shouldn’t cause any issues. As long as you have replaced the battery like for like. Eg AGM / EFB and the AMPS match you should be ok.

Where are you based?

Your duff SB may well be the reason the stop/start isn't stopping and starting.

A search of the forum will relieve your ignorance. There’s plenty of definitive information available at your fingertips. Search for @Dellmassive’s “How I done it” threads. There’s one dedicated to changing the starter battery.

Yes, I hadn't considered that. I've just lost power steering to add to the problems too. I need to check the auxilary belt tomorrow. If that's failed, I don't want it causing cambelt damage. I suppose the loss of power steering too could be linked to the electrical system & could be caused by battery failure ?

I have had a similar issue on a previous VW where I would get a start stop error and the power steering would drop out when the error was showing, this only showed up a voltage low issue on a diagnostics. Turned out to be a faulty voltage regulator like this

Thread 'Upgrading Starter Battery - how to guide'

12 Jun 2019

My van (April 2017 T28) is fitted with a Moll battery.
I am experiencing some issues with it not starting after a few days sitting on the drive. Now this could be due to the tracker I have fitted draining it but I doubt it, I'll do some drain current tests before taking the plunge.
If I were to change the battery myself, could I replace it with a larger capacity one (eg a 95Ah 850A G14 Varta AGM which should just fit in the battery tray) instead of the standard 70Ah 700A Moll?
Is there anything I need to do to let the van know it has a different battery fitted? (I have VCDS if needed)

Many thanks for all your replies & suggestions. After looking carefully this morning, the auxilary belt is off the pulleys, so that accounts for the flat battery & power steering problems. Thank god that didn't happen on the motorway last week. There is no protective under tray fitted either, but assume it would have had one when new ? Anyway, it will be going to the garage on our trailer. Definitely needs a serious going over.

Thanks for letting me know that Pauly. I thought some lazy mechanic had forgotten to refit it. Mine is a panel van, but I’m definitely going to need one, as the van has to go up & down a very rough bumpy track every day. I’m guessing I should be able to get one somewhere for a reasonable price ?

I think this is down to the mood of the factory tbh. My 2017 Highline PV came came with full under trays. Dunno if the Highline had any bearing.

There was an undertray for sale in the for sale section a few days ago
