I was trying to start my GTI the other day after winterizing but the battery kept dying. I had accidentally turned on the water, and after ~5 mins of trying to start it I realized my mistake and turned the water off. When I finally got it started the engine was sputtering. It behaves like it may be bad gas, but could I have gotten water into my engine? How do I fix it?

Left water on too long when flushing, now engine sputters

Before you fire it again...pull the lugs. Then try to start. Did water shoot out? Next....check the oil. You're looking for chocolate milk. If you find it....you are in for a series of oil changes. You must get the water outa the motor ASAP. If you don't see milky oil.....replace plugs and try again. Hopefully you didn't bend a rod.

Sorry...meant to say "plugs".
Since water doesn't compress you gotta get it outa the cylinder before fckn up somethin real bad. Glad it wasn't that bad. Hope your final oil change included wet clutch compatible oil.

Keep turning engine over with spark plugs out until no more water comes out of cylinders. If there is a way to disconnect fuel pump and or fuse do it, you dont need fuel being injected while turning engine over with spark plugs out.
I think if you hold throttle wide open it cuts the injection, im not a 4tec guy so wait until someone answers in here how to cut off fuel.
Check the oil for water ingress, it will be milky like a chocolate milkshake which means water got in your oil and multiple oil changes will have to be performed to get all the water and residual moisture out. One oil change will not be enough.

holding the throttle will prevent fuel injection this is the same step taken during winterization to coat the cylinders with lubricant/fogging oil

guessing you understand that they both mean it has to be WOT wide open throttle not just part way..
I assumed it was WOT but wasn't sure. Pulled the plugs and no water came out of the cylinders when I turned it over. Checked the oil and it looks like the aforementioned chocolate milk. So do I change the oil, run for a few minutes, then repeat? How do I know when it's good?
While I concede water in the oil is bad, I'm having a hard time seeing how that would cause the sputter/hesitation.

Get PLENTY of cheap oil. Pull your filter and put the cover back on without a filter. Drain and top off. Let it run for less then a minute. Drain and refill. Keep on doing this until no more mixed oil. It can take five times or so. In the end, drain the cheap oil, put in good oil and a filter,
Change this oil in 5-10 hours. At a minimum, change the filter after the first run and top it off.

um correct me if i'm wrong here. but you can spend $500.0 on oil and you will not get rig of the water in the block. in the manual there is a way to boil out the block

Depends on the amount but I agree as a whole I don't think thats your overall problem I think unfort running it like you did created a separate and honestly prob worse problem esp if something bent or got damaged as then your looking at a rebuild then not just a misfire or fuel/electrical issues
That's what I'm afraid of, although I'm hoping maybe the water just fouled the plugs. I don't hear any knocking or other strange sounds, other than the skipping.
I'm on round 3 of the oil changes - will resume in the AM.
That's because it is all nice and steamed clean now,,,
I'm betting you don't make this error again.
Glad you are up and running.
It fills the exhaust up and the water then sits on top of the engine. The moment you crank the engine, it gets sucked in right through the intake valves.
You should always fire the engine and turn on the water once it fires. Never turn on the water before the engine is running.
That's how I have always done it (and have always been told). The engine can run for at least a few seconds without water.
Take your ski out and ride it for a good hour or so. The heat in the engine will evaporate oil in the block, especially if you are running it hard.

AGREED! Pull the plugs and change your oil!! Make sure all of the water is out.
Good to know had no idea that was possible
