Somebody needs to make sunroof maintenance and protection kit!
This is too catastrophic.

Rains like heck over here too in the PacNW. Roof drains have been an issue for me in lots of cars: the various Porsches that came through, VW Beetle, etc. Lots of gunk to clog things up. I've using compressed air and steel wire.

Depends on the water quality for damage. Pure water will not conduct and nor will it do much damage corrosion-wise. Best thing to do is pull disconnect the battery and start a drying process.

If it flooded the harness, well long term issues, chasing electrical faults. Total the car just to avoid future problems - a shame but I can see the reasoning. Labour $$.

Now for the ultimate sunroof-clogged flooded monster check out this one. It was nasty

FWIW, if you search you can find a post from a guy who seemed to have the best and simple DIY. He used basic weedwacker plastic line with a dulled end. Helps avoid chance of hard wire or something similar digging into/puncturing tubes. Air compressor type air definitely not recommended. If a drain line blows or disconnects somewhere internally that is clogged with some exuberant air pressure, the hurt is only just beginning.

Replacing sunroof and roof lining also going to finally get it tinted
Thinking my sunroof has never leaked but I will check all the drains while I am at it.
All four blocked!!
Got the dewalt vag and duct taped to the hoses one by one and vacuumed till they were partly unblocked then taped the hose to it on low.
Cleaned them all.
Front left was already full of water before I started.
Front right leaks somewhere down the windscreen pillar.
I might put a silicone plug semi temporary permanent in it for the time being until I decide if it is plausible (possible) to fix it.
Best thing to slide inside the hoses would be the hose they use on fridges and water coolers.
It's about 5mm flexible but rigid enough to push through.
Only had about a meter of it and was not long enough.
I don't think the sunroofs leak much when closed.
So if you have not checked your drain hoses you may be in for a shock one day.

Vac the hose

Caught up with young dodsky (Andrew ) before he went back south.
He knows what dodgy drain hoses do its a pain.




Flush the hose

I know this is a late reply, but hoping you are still monitoring! The exact same thing recently happened to me, and my insurance company denied my claim for "wear and tear," and later maintenance? How did you describe the situation to your insurance company that they covered it?

Like I always say; Insurance COmpaNies are your friend, until something goes wrong.

That's why I don't waste money on insurance.
