need help! Coolant found in head mk7 gti 2018

[Daser Drives]

I have GTI 2018 mk7.5 US spec with filter custom downpipe and jb4 map6 by george.. and recently i started loosing coolant quickly and couldn't find the leak anywhere in engine bay..
So went to the workshop and they found water leaking into the heads over pistons specially 1 and 4 cylinder but the car ran totaly fine and never overheated neither any smoke..
Can someone guide me through this and explain me what happened exactly btw the car is still in workshop and being worked on currently.

Sounds like a blown head gasket. But you should see it in the exhaust.

^this. head gasket is easiest and most likely answer

Remove downpipe. Remove JB4. Take to dealer. Invoke warranty powers.

Clear the codes, pull the battery then do a drive cycle once the JB4 is off.

No clue if this help clear out anything tbh but I've heard this repeated a few times from local VW people.

Also remove any performance-type shit from that car, ie stickers if you have em lol. Even better is if you have your mom take it in

Yeah alot of water coming put of exhaust though.. but what do u think about reason of it happening? is it the jb4 map6 hitting 26psi? or something else?

Actually am staying in Middle east and car is imported from USA so no warranty jst have to fix it in local workshop who are specialist in VW..

You're probably only seeing water come out of the exhaust when the engine is cold. It would burn off if the engine was up to temperature. If you had that much water running into cylinder 1 and 4 it wouldn't run fine.

So they replaced the water pump?

yes Really weird but i was definitely expecting headgasket... now the car doesn't loose coolant at all and runs fine!
But disappointing because i already replaced the waterpump twice and am at just 26K kms.
