Drain caps is what prevent critters from entering the drain? Service advisor told me about those...
It's been 2 day. They will do the step 2 of the recall at the same time... Funny because I'm considering doing a delete next year.
The rear ones take about ten minutes to remove. You could check the flow rate before and after removing them by parking slightly uphill and pouring some water into the catch tray. I bet they barely flow with the "valves" in place"The itsy bitsy spider went up the Golf drain spout..."
But seriously, I think sticking check valves (not really caps) explain why, for mine, there's only leakage with extreme rainfall rate; with normal rainfall rate or car washing its bone dry. Extreme drainage probably overwhelms them when they're sticking or restricted from dirt buildup. I'd like to remove them, then do a water nozzle blast around the sunroof perimeter, but ideally remove the headliner first just in case the real culprit is the bad sunroof frame seal issue per the TSB.
The difference in drain flow with the caps removed is huge. I suspect a large percentage of leaks are due to the caps not allowing high volumes of water to be drained fast enough, or as in my case not at all.Yea my sunroof only leaked during heavy rain storms. Other than that I had no issues. The only problem is the dealer could never "recreate" the leak so they haven't fixed it.
You guys keep calling these spider caps but if they're really the size of dimes than even rodents as large as mice could fit up in those tubes. Not sure why they would, but they could .
BummerLove my sunroof and am happy to have paid extra to have it.
Today, however, a truck in front of me with an unsecured load spit out a large rock that shattered the front portion of the roof.
Has anyone has the glass section in front replaced? It appears they will need to disassemble the entire headliner and replace it. I hope all goes well. Are there things I should look out for? TIA.
Sounds like you passed the truck and flagged him over, nice work !Thanks for the replies. It shattered and rained glass on me at each bump on the way home. I put on a ball cap backwards to keep the glass out of the neck of my shirt. Yes, your butt can get cut on those pieces of glass as you bounce over various bumps on the road, should you ever need to know! Glass replacement is not in Alaska, and can't be shipped the fast route. Hoping to have the car back the end of next week. It is tinted and laminated, but can't hold its own weight once compromised. I'm glad this occurred on a warm [for us] and rainless day. The headliner inside must be removed and replaced to get the glass out and replace it. I'm guessing about $2500 to the other insurance company, plus cost of the rental. Cheap at twice the price.
Because there can be several causes of leakage, it all depends on whether all causes were correctly identified and then correctly repaired. If the answer is yes, that should the end of it. If not, its still possible to solve it if you have the patience and your dealer is responsive.Hello,
I've seen quite a few posts about roof leaks on alltrack SE/SEL trims.
I'm on the fence about buying one.
Can you confirm whether the fix(es) implemented by dealerships actually fix the problem permanently? I'm looking at used 2017 that were bought back by dealer accuse of the said issue, which was supposedly corrected. Thank you.
Is the water hose test at the dealership sufficient to determine whether the issue persists?Because there can be several causes of leakage, it all depends on whether all causes were correctly identified and then correctly repaired.

It would be helpful to carefully inspect (with good lighting) all of the headliner for stains and, if present, to possibly determine if they were a legacy of pre-repair leakage (reflecting poor finish work by the dealer) or occurred post-repair while sitting on the lot.
No. A storm with a rainfall rate of 0.5 - 1.0"/hr. is the acid test. My drain tube end caps would not cause a tube back up with heavy hose spray or rain rates below this.Is the water hose test at the dealership sufficient to determine whether the issue persists?
