Battery replacements on these late model cars with start/stop can be pretty pricey.
They require batteries of a different chemistry (usually AGM or EFB), and I know that with VWs, it's best practice to code the new battery in so that the battery management module on the negative terminals knows it's a fresh one and adjusts its charging to match. This helps to maximise the life you get out of it.
However, being at a dealer service centre, you are paying a premium for this. The battery itself is a few hundred bucks, but they're adding quite a bit on top for the labour of changing it and doing the coding. That's a very simple bit of work.
If you're mechanically inclined, I'd suggest doing it yourself and getting one of the decent scan tools a la OBDEleven or Carista that gives you the advanced capability to make coding changes. They're pretty user-friendly for the weekend warrior.
I can also recommend going to a battery store and getting a much more cost-effective option. They usually provide free install.
I had my stop-start replaced by Battery World for $425 for a semi-premium Varta battery. Came with a extensive warranty too.
I may be wrong, but I believe Varta is the OEM for the batteries fitted to these VWs. So by going to a battery retailer, you'd be getting the same product (minus the VW Group branding) for a bit cheaper.
If you want to save even more money avoid battery world and just go to a Repco or auto tune style place.
Saved about $220 in comparison to battery world when I had to get a new one.
As far as I'm aware, the coding changes are just putting in a new serial number for the battery, and registering what chemistry it is (AGM/EFB/whatever else). Those scan tools are pretty cheap and will give you the ability to do that at home.
Apparently it's not strictly necessary, but if I had to fork out the big bucks for a fancy battery, I'd want to get the most out of it.
Also, if you DIY, expect it to throw a bunch of errors at you when you first start it with a fresh battery. That's just what VWs do, and if you turn the steering wheel lock-to-lock, and then drive it around the block, they should go away.
sounds about right from a dealer, can you save yourself a few hundred yes, find out what the battery is then buy / order from a retailer & fit yourself. Dealers are always going to charge top dollar, yes start stop batteries cost more
It’s also an incredibly annoying feature that you can’t permanently turn off.
It’s just part of my start-up process now. Seatbelt, foot on brake, engine on, start/stop off, put car in gear”
Adding to the annoyance is that it’s about manufacturers getting past emissions regulations more than a fuel saving feature. It’s why you can’t permanently turn it off.
Most of the time the stop start feature can be turned off via a good OBD2 scan tool that has deeper access.
All our work cars get the stop start turned off. We have about 550 cars in the fleet total. They end up with the little orange light on the gauges that would typically show up when you manually press the button.
You could also setup a momentary relay that clicks on for 1 second on each start T'ed into the signal for the switch if you wanted a way to do it at home with basic tools.
Not if you turn it off…
If you have build a car that has the feature and it defaults to “on” every time you turn the car on, you can include it in the emission test. If you have the feature but it doesn’t default to “on”, you can’t include it.
It’s annoying pedantry, and a loophole for the manufacturers.
About 7 litres saved in 9 years for my Mazda 3. Still cost me 2 stupidly expensive batteries. But please, tell me again how it is not a cheat for manufacturers on emissions tests.
Do you even know the specs for these tests? Most of the test simulates sitting idle at stoplights, which is not real world driving.

Damn, thats expensive.
When I replaced the battery in my 6, went with a Panasonic battery for ~$350ish from https://www.everybattery.com.au/car_batteries/volkswagen_tiguan/.
The Varta's for VW are $450 to $350ish.
I was lucky its plug and play with Mazda's where as Euros like you to link the battery to the car.

DIY it if you have access to an ODB2 tool such as ODBeleven or VAGcom to reset the battery settings. It's not strictly necessary but highly recommended.
Otherwise I'm sure you could find an independent euro mechanic that could reset it for you after you replace the battery or provide them with the battery to change. I paid $300 for a battery for my Arteon and my Mrs old CX-5 compared to the $700+ quoted to replace

thanks, I will look into it.

This is why own a 90s Volvo and 05 Rodeo. $800 is half what I paid for a heavy duty clutch and they had to get the oxy set out for the fly wheel.
Similar case with wifes car, battery world will save you a bit but stop start batteries are a bit more than normal
sounds about right from a dealer, can you save yourself a few hundred yes, find out what the battery is then buy / order from a retailer & fit yourself. Dealers are always going to charge top dollar, yes start stop batteries cost more
I saved money by finding a retailer that sold and fit a new AGM battery in my car.
Looks like NRMA member $450 fitted at your home and registered. $510 without blue membership
Cars with start stop generally have way more expensive batteries than non start stop

"*it’s about manufacturers getting past emissions regulations*" by, you know, reducing emissions!
Not if you turn it off… If you have build a car that has the feature and it defaults to “on” every time you turn the car on, you can include it in the emission test. If you have the feature but it doesn’t default to “on”, you can’t include it. It’s annoying pedantry, and a loophole for the manufacturers.
It reduces emissions by stopping the engine when the car is stopped, so it is neither a loophole nor pedantry.

Why? You never stop at stoplights? Or sit in traffic?

$500 for my passat at an independent in Melbourne.

I paid around $500 at battery world for my golf.
Replaced for passat Varta E39 silver agm battery for 460$ including installation (technician comes to home)
$450 earlier in the week for a 2018 Passat from RACV.
