Clearing blocked sunroof drains - RetroPug - 28-03-2014
I've been trying to clear a blocked sunroof drain on my P1. I've blasted compressed air down it, which came straight back past the gun, so I then removed the headliner and the tube from the sunroof and stuck the gun down the tube hoping to get a better seal and the air still came straight back out. Whatever is blocking it is really stuck in there. I've also tried one of those drain unblocker cable tube things and couldn't push whatever is down there through, it did go down a long way though, so I assume the blockage is crap getting into the bottom from the wheel arch end.
Are there any other good ways to unblock it? For example, is it easy to get at the drain in the wheel arch, and if so, where actually is it?
I've considered using bleach, mister muscle, boiling water etc. but I'm not sure how the rubber drain pipe would tolerate this and as it is literally inside the a-pillar I really don't fancy it degrading and falling to bits.
Does anyone have any further ideas, or know whether or not the rubber would be tolerant of any of these methods?
Thanks.

Id also like to know incase mine is blocked, I really dont want to get rid of the sun roof.

Using an air line worked great on my old 106, but whatever is in this one is really stuck!

Just pull the end of the tube off, tape some new tube to it, and pull new stuff through. About £2/Mtr for heater hose or similar.
If you can't be faffed with that, maybe try ramming a wire coat hanger down there?
RE: Clearing blocked sunroof drains - RetroPug - 28-03-2014
I tried a proper drain unblocking tool cable thing and couldn't push it through, however your idea of simply replacing the pipe that way I hadn't thought of! Great idea.
Do you know precisely where the tube runs to in the wheel arch?
RE: Clearing blocked sunroof drains - Grant - 28-03-2014
The front two run to behind the scuttle panel and the rear two to in the rear quarters. Well that was on mine, and its a 3dr. Not so sure about a 5dr.
Dunno what you have mate lol

Ph.1 gti-6 so a 3-door.
Oh right so to get at the other end you remove the scuttle panel...sounds pretty straightforward!
Thanks a lot mate.
RE: Clearing blocked sunroof drains - Grant - 28-03-2014
I'll double check. I just ripped mine out as I removed the sunroof. Memory doesn't serve me too well as i just ripped them carelessly
RE: Clearing blocked sunroof drains - RetroPug - 28-03-2014
Thanks!
I'll have a look, should be able to find them! I just park on the kerb so water drains out of the clear side at the moment.

RE: Clearing blocked sunroof drains - AustinAR - 31-03-2014
did you have much luck clearing them? think've got the same issue now, tried wire with no luck
RE: Clearing blocked sunroof drains - Niall - 31-03-2014
Don't use a wire coat hanger!! Thy are a really soft rubber so you will punch a hole in the side of it somewhere and let all the water fill your car up somewhere lol

An air line normally works alright and I've used it before on another pug but this blockage seems to be really hard to shift so I'm going to attempt to replace the whole tube.
To stop water getting in in the meantime, park up on the kerb on the blocked side so that the water drains out of the clear side.

Phew that was going to be the next step haha I've only used some dodgy old wire so far..!
Do the pipes run into/past the rear arch, i've got what looks like salt/old water deposits around where the rear speaker connector is... (hope that makes sense haha)

I've heard that the problem could also be that the drain pipe is improperly routed and could be trapped/pinched closed somewhere, it is entirely possible that when the cambelt was done before I bought it that it could have been tucked out of the way (the blocked one is on the same side) when the wheel arch was removed to gain access. I will be checking this as well but have no time for a few days.
RE: Clearing blocked sunroof drains - RetroPug - 21-04-2014
Right.
I removed the wheel arch liner and the wing, I cannot find the drain pipe at all, I think it is inside the box section of the chassis that is behind the top of the wing. Having watched water drain out of the other side, it doesn't come into the wheel arch it comes out of the chassis behind the wheel arch, near the front of the sill.
I've really no idea what to try next...can't see the bloody pipe anywhere.
All helpful suggestions appreciated.
RE: Clearing blocked sunroof drains - Tom - 21-04-2014
Ive always used a big syringe filled with water, never had one i couldnt unblock....
RE: Clearing blocked sunroof drains - RetroPug - 21-04-2014
A compressed air line could not unblock it, and neither could a draper pipe unblocker.
Really need this draining water now!
RE: Clearing blocked sunroof drains - RetroPug - 22-04-2014
Does anyone know the precise routing of these drain pipes on a 3dr shell?
I didn't completely remove the scuttle panel so that might be the next thing to try?
RE: Clearing blocked sunroof drains - daddyfixit - 14-03-2017
was this ever solved ?????
RE: Clearing blocked sunroof drains - RetroPug - 15-03-2017
I was never convinced I'd fully solved it, but I haven't had a leak since then and this thread is nearly 3 years old.
I used airlines down the drain holes multiple times, and used a draper pipe cleaner/unblocker tool which is essentially a springy wire that is easy to slide down pipes and tubes, and finally I think a lot of the water was coming in through the aerial. I bought a new, genuine base and used some clear silicone underneath it.
If you are anywhere near Leicestershire feel free to borrow the pipe cleaner thingy.
