Did you do any of the ISTA tests? When/how did you do the filter changes?

Story: I just bought my GTS a couple of months ago and did a track day 2 weeks ago and it didn't use any water. Pulled a single code, 124015, Water injection, working area: Pressure area too low. Which I hope is just the water filter. I just did my first one and there was a bit of gunk on the bottom of the filter, but not a ton.

I didn't run any ISTA tests, just noted how water wasn't being consumed. I basically checked the filter after each opportunity to run the car at WOT, if it had build up I would change it which it did about 3-4 checks in a row, then after that it started consuming water and would only have build up after 1-2 track days.

It never threw a CEL or any error so I never scanned it for codes. My advice would be to run it at WOT as much as you can and check the filter after. Also look down into the opening below the filter to see if there is any build up in there, I used a shop vac and tweezers to pull some out a few times.

Thanks! This gives me some hope that I don't need a new water block. The local dealership said there isn't much they can do without a CEL.

As far as I know, no one has posted the ista tests
I'd love to do them if they are available!
