Where Your Author Learns More About Volkswagen Golf Water Leakage


It’s time once again for an update in the Golf Sportwagen’s precipitation issue. Last we spoke, I’d noticed an initial musty smell in the Golf, and considerable headliner staining shortly thereafter.

After some delays in the service appointment process, my local VW dealer has a solution for me.

I’d booked an appointment via the dealer’s website for the morning of May 14th, but never received any sort of confirmation. To be safe I phoned them up on the 13th to verify my appointment, but was told they wouldn’t have a car for me as specified on my request. No one called to tell me this, I’d just have found out when I went to drop off the car. Surefire way to get me irritated, but I digress.

The associate relayed the next day loaners were available was Monday the 24th. So I pushed the appointment back another nine days. Meantime, a particularly soaking storm that following Monday revealed a drenched headliner at the rear driver’s side of the Golf, and water running down from the D-pillar into the cargo area. Not good, but not much I could do.

Upon return to the dealer on the 24th for my 10:00 AM appointment, I showed the service advisor the issues, made more extensive by the recent rain. By then the staining had made its way forward to the C-pillar. I was informed there were no loaner cars available, but they’d get a car from Enterprise for me if I’d wait a moment. Sure, fine. Meantime, another customer brought back a loaner which they quickly cleaned, and sent me on my way. It’s on expired tags since March, and you’ll be seeing a review of it shortly. Can you guess what it is?

Tuesday evening the service advisor called me with the prognosis: The rear valve flaps on the sunroof drains had become stuck, which backed up water into the headliner. Water also flowed onto the sunroof glass at some point, which also ruined the sun shade. There are four drains on the Golf, two at front and two at the rear, and each has a drain flap. There’s a TSB for the repair, and the fix is to remove not very necessary flaps altogether. They can apparently become stuck via dirt and debris, or just generally stop functioning. The service advisor said they were stuck, but did not mention the cause was debris. The car is not parked under any trees, by the way.

The fix is not a quick one since the headliner has to be replaced once more. Parts won’t arrive until Thursday, then there’s a long weekend with the Memorial Day holiday. I know from my last experience that the service department has exactly one technician who works on headliners, and once he gets to it it’s a two-day job. Current ETA is midway through the first week of June.

As I type this story it’s pouring rain in Cincinnati, but at least I know the roof drains are clear and that fresh rainwater is flowing freely onto the dealer’s service lot.
