Interior Water Leak in VW Tiguan – Two Leaks Found After Full Strip

When Your Car Starts Leaking Inside – It's Not Always What You Think

We had a Volkswagen Tiguan in this week with a major interior water leak. The customer noticed wet carpets and condensation, and couldn’t figure out where the water was coming from.

At 1Stop Motor Shop in Newtownabbey, we removed the interior carpet, trims and discovered two separate leaks. Water leaks like this can be caused by anything from blocked drainage channels to worn seals and they’re not always easy to spot from the surface.

Common Causes of Interior Water Leaks in Cars

Interior water leaks can soak your carpets, create bad smells, damage electrics, and even lead to mould. Some of the most common causes we see include:

• Blocked sunroof drains

• Leaking door seals or grommets

• Cracked bulkhead seams

• Clogged scuttle panel drains

• Rear light or tailgate seal issues

In this VW Tiguan, both issues were hidden and only detectable once the interior was removed. This is something most garages don’t have time to do thoroughly.

What Are the Signs of a Water Leak Inside Your Vehicle?

You might have a hidden leak if you notice:

• Damp or soggy carpets (especially under mats)

• Fogging or condensation inside the windows

• A musty smell in the cabin

• Water sloshing noise when cornering

• Warning lights triggered by wet electronics

If your car smells damp or has moisture build-up, don’t wait — we can find the source and fix it before it causes damage to the interior or electrical systems.
