Sunroof drain missing!

It's a PITA...are you sure the whole thing is missing?  I'd make darn sure that it's all gone before delving into a replacement.  

 

The flexible plastic drain tube fits over a metal nipple that's welded/soldered into the drain channel at the front corner on each side of the sunroof opening.  To install another tube, you'll have to pull the headliner back so you can see that upper end, then thread the replacement hose down to the opening in the inner fender where it exits. 

 

I've never had to replace one, and don't know anyone who has, unless it was part of a roof transplant.  I think it might be easier to thread the hose in from the bottom, then up the A pillar rather than the reverse.  Or possibly use a smaller diameter hose whose OD is slightly smaller than the ID of the upper nipple.  Then you wouldn't have to unfasten the headliner to access the nipple's back side.

PS.  Truth be told, if the sunroof seal is newish and the sunroof is properly adjusted, you shouldn't even have any leakage into the drain channel and thus the hose would be unnecessary.  But that's in theory.

I have replaced the drain tube by pushing a stiff wire (welding rod) up to the roof and then pulling the plastic tube down... if you try to push the plastic 'bunches up' and jams, if you pull it then it shrinks in diameter to get past obstacles....no fun but not too stressful.

Great sugguestion: ) I knew when asking this wasn't going to be an easy one. The good news is the one on the other side drains very well. The missing side drains, and comes out at the rocker panel seam below the door. 

Are there rear drains as well?

There are rear drains as well.  They come down the C pillar, then forward of the wheel well into the space behind the rear interior side panels.  Those rear drains empty into the rocker panels and should be relocated to drain into the wheel arch to avoid any further rust issues.

Everybody has been so, so helpful in the past when I have asked questions, I thought I would chime in.

Member jgerock posted photos of the drain locations, tubing, clamps and the plastic fittings on Sep 8. All of them very helpful and self explanatory. He also referenced Keith Kreeger’s very cool website "my2002tii.com". I had stumbled on it years ago and it is really great reading on the restoration of a 2002 from finding a car to complete restoration. It has good photos of the drain locations and the tubing in the index(top left of webpage) under Aug 2004. Running the tubes is covered in July 2004. 

Good Luck!

Thank you!  My goals for posting here is to help others and reference where I got the idea(s) from.

An update. The problem with the left front drain tube has been found. Evidently the drain tube was cut when the radio antenna was installed. The tube almost makes it to the bottom of the windshield. The trouble is water drains down and catches the antenna cable which brings some of the water in the car. Fed wire through tube and out the proper exit. Also peeled back the headliner in preparation to replace it. Access is limited and the wire is there for pulling it through. I just need the tubing. Also the rear drains just needed simple cleaning, and drain well.

Thanks to all that helped on this!

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
