..... if you want to be really controversial and divide opinion -

Change your 12v rear boot socket to be permanently powered, then install a little 5w or 10w solar panel on the rear parcel shelf to help trickle charge / maintain the battery ;)

If you don't do much milage or mainly short trips, it can work wonders for the smooth running of the start/stop and electronic handbrake systems which can be a little voltage sensitive.

Through personal experience and that of friends, so glad I've always had an AGM battery installed in my current and previous car - they just seem to be able to handle technology loaded cars better.
From the manual.......

The manual can say whatever it wants, on a whole host of things - if you don't have the knowledge and/or experience of what you're doing with your car then it's probably best that you don't do anything that the "manual" or the "car manufacturer" doesn't approve of full stop, irrespective of car age or warranty status.

As I said, many will think such a suggestion is controversial, especially for the very reason you have highlighted - I fully admit I should have included that known caveat from the manual in my comment, but I do believe people should personally both research and be confident in whatever they do in the first place - number one on that list would be reading their car manual in that specific area ;)

Popped into the dealer yesterday and they had a Tiguan in the show room on trickle charge. The charger was a CTEK, connected to earth and positive terminals.

The dealer was surprised when I told him what the manual says about charging.

It seems to me that charging is fine with a good quality charger, but VW probably find it easier to advise against it rather than testing and approving chargers

The correct way to charge the battery is as shown on the battery terminal covers.
Connect the RED +ve lead direct to the positive terminal on the battery.
Connect the BLACK -ve lead to the metal earth star point post on the bulkhead directly behind the battery.
This allows the battery sense electronics fitted to the negative terminal to monitor battery parameters.
I have used this method many times without problem (using a CTek smart charger) and with the battery still connected to the car.
With regard to the fitment of AGM batteries- it appears VW changed to EFB+ batteries for more recent models. Original 2016 Tiguans seem to have been fitted with the superior AGM type, as mine was.

My 2019 R-Line has a AGM battery. Anything to do with regenerative braking?

It's possible- but the Tiguan doesn't have true 'Regenerative Braking' in the accepted sense.
It has electronic control of the alternator which changes the way the car charges during braking.
True regenerative braking is only found on the electric VWs, where energy built up during forward motion is converted to electricity by motors on the wheels, to charge the batteries during braking and slowing down.

I’ve just checked and my Tig is fitted with a varta AGM battery so not sure about the statement about VW fitting EFB + batteries.

Having an AGM or EFB or EFB+ type battery fitted at the assembly plant is probably more likely a supply and demand situation at time of assembly/location - in reality we'd all hope every car was fitted with the better battery - based on our technology loaded cars that's probably the AGM battery.

I'm seeing this from the perspective of types/manufacturers of tyres which are fitted at the assembly plant. There may well be a cost factor on some occasions, but we're never really likely to find out.

milligan - my statement about the battery type was based on the responses to this earlier post:
