▶ When a vehicle gets booked in to fix a water leak, the problem is usually due to the cooling system. However, this 2001 Peugeot 106 had a water leak from outside. The problem was so severe that the driver’s footwell had a puddle deep enough to float a paper boat!
With no apparent loss of coolant, we immediately discounted the possibility that the liquid was from the cooling system and had entered via the heater matrix. Opening the bonnet, we noticed that the front scuttle panel was full of old and decaying leaves. It was then only a short step to discovering that the drains in the front scuttle were blocked, allowing rainwater to build up until its first exit point was through a grommet hole in the bulkhead and into the vehicle.
Rainwater had overflowed into the vehicle, forming a large puddle in the footwell.
