New owner and question for replacing the distilled water in the reservoir

[EXIA2023]

Hello guys, I just bought un brand new GTS, only 73 km on it, really excited with my purchase.

I just got 1 question which I did not find the answer on the internet.


As this car has nearly never been driven since the last 6 years, I am thinking about to replace the distilled water in the reservoir, but I did not find any information about how to do it, as I dont want to break something and not familiar with this water injection.

Do you guys think it is necessary to replace the distilled water in the reservoir in this case ?

And do you have any way to replace the water, we need to disconnect the 3 connerctors and pull out the reservoir to replace the water ? or is there any other way to do it ? or bring it to dealer ?


Thank you guys.

Welcome! Nice to see another Canadian owner

I’m sure there’s an easier way, but you could always siphon it out with a long tube.

Appreciate for your help! Yeah, I’m in montreal, nice to meet you! I will try the siphon to pump out the water.

Congrats on the purchase! Personally I would certainly drain the tank and fill it with fresh water as you never know what someone put in there before you, even with the super low miles. Fortunately removing the tank is very simple, I posted about it previously here: https://f80.bimmerpost.com/forums/sh...7&postcount=33

Thank you ! This is exactly the thread I was looking for !

To pull out the outlet water line, do you have a picture zoom in which indicates where we need to push in with the bouton ? As I looked at that connector, but afraid to force it in a wrong occurring the damage.

Thank you!

I’ll definitely reference this when I pull my GTS out of her winter hibernation

I don't have a close up picture but I recall it was a black plastic button on top that you push in and then pull the connector out. Just be ready because the water will start pouring out!

I’d also suggest replacing the stone filter after sitting that long.

Thank you guys ! I just take off the tank and replace all the water inside with the fresh distilled water bought from Walmart.

Appreciate for all the information here!

That’s a good idea! I will definitely do it next week!

By the way, to change the stone filter, any thread with pictures attached to demonstrate ? I search also, look like people talk about it a lot, but not really have some pictures to show the step by step? Sorry for my question again and again ~

Did you see this thread? It’s a very simple process, save for trying to remove the filter without the right size tweezers

You’ll clearly see what needs to be taken out to access the filter

Appreciate for the photo, very clear to see the big nut above. And I see the difficult part is to pull out the filter which located inside. I will loose that nut and see how it looks like to pull the filter inside out.


Thank you!
