Wet carpet, dry-looking roof
Silted drain channelsHow it shows up
Damp front carpet, a musty smell that won't air out, fog on the inside of the windscreen, or a headlining corner that's tide-marked after a storm. Sydney's leaf litter and road dust silt the drain channels quietly over years; the gutter around the glass then fills faster than it can empty and the overflow goes into the cabin instead of under the car.
Why it gets misread
Because the water surfaces at the floor, the usual suspects get blamed first: door seals, windscreen, even the aircon. We regularly meet Tiguans that have had silicone run around the glass, which seals the roof's designed drainage shut and makes the next downpour worse. The glass was never the leak.
How we fix it
Controlled water testing until the true entry point shows itself, then every drain tube flow-tested, cleared and flushed, perished seals replaced with OEM or premium aftermarket rubbers, and the carpet and headlining checked so you're not driving a terrarium. Water-tested again before handover, under our parts & labour warranty.
