    Thread: Sunroof Drains

    1. #1

      Sunroof Drains

      I've just brought my 2008 XC70 back to my dealer for the third time for what appears to be a clogged sunroof drain that results in water filling the driver's side footwell during heavy, prolonged downpours. It even overflows the high-lipped Volvo rubber floor mats, soaking the carpets.

      The Service Advisor believes that the occasional high pollen count and other debris may be the cause of the clogging. I live in NE NJ.

      I park the car outside, in my driveway, at a slight nose-down angle (approx. 7%), and it was suggested that this may be contributing to all the drains not being utilized.

      The dealer has been very helpful and apologetic and insisted that they keep the car for several days to remove the seats and carpets and thoroughly dry everything to prevent any mold or mildew from forming. They provided me with a very nice loaner 2010 V50 for as long as it takes!

      None of my previous Volvos with sunroofs, 2 XC70's and an XC90 or my current S40 have sunroof drain issues.

      Has anyone else experienced this problem?

      I have read of this being a consistent problem with certain years of the XC90 but this is not something I have ever read about happening with an xc70...

      I know this is not directly helpful but I thought I would mention it anyway...

      Dbone;

      Thanks for the reply. Our '04 XC90 was always dry!

      I'll post when I get an definitive answer from the dealer.

      Cheers...........

      Do you have your sunroof open often where large debris can get in? The drains should not clog like this with just pollen running around and a closed sunroof.

      After the first incident, I got a bit paranoid about making sure that there was no heavy debris in the sunroof opening. They still clogged.

      My Service Advisor just called and said that they made some modifications to the drains per a Service Bulletin. (alas, the carpets won't be dry for a few days, yet).

      I'll post when I get more details on the Service Bulletin.

      Thanks for the reply.

      Since this isn't your first go-round with this problem, I would highly recommend pulling the carpet yourself to inspect for mould when you get the car back.

      I got my XC70 back from the dealer clean and dry. (I followed 'adykes' recommendation to pull up the carpet and check for any mold or dampness myself. The dealer did an excellent job.)

      My Service Advisor said that there was a Service Bulletin regarding sunroof drains in early 3rd generation XC70's (as well as some later XC90's) that had the dealer enlarging the drain openings. Sorry, but I didn't get a specific SB number.

      Hopefully, the problem is cured. I'll post if it happens again.

      Thanks again for the replies.

      Cheers.......
