2005 Volvo S40 T5 sunroof is leaking water. Any suggestion to fix it?
How bad is the leak? A 'Factory Fitted' sun roof will usually leak for a few common reasons. It isn't closed properly, (Yes I've done that!). The drain channels are clogged and full of dirt so the water is pooling up in the runners and leaking in. The seals are starting to fail. On a 05 plate the rubber seals will probably be the factory originals so will be old and may have started to go bad so the sunroof isn't watertight anymore.
Your first option is give the rails and sliders a good clean. Open the sun roof to it's widest and give the runners and the channels a heavy duty clean. An old toothbrush, toothpicks and cotton buds are great for getting into the troublesome areas. When clean lubricate the moving areas with Silicone Grease.
Standard types of Grease or Lithium Grease are Petrolium based so can be bad for rubber seals, Silicone is mineral based so doesn't damage the seals.
