Good afternoon all, I’m after some help! Been losing coolant, drivers side carpet is soaked, interior heating not as warm as it should be (literally only luke warm) even after long journeys. Been to a few garages who say they don’t believe the water inside the car is from coolant, they think it’s rain water, they’ve done a pressure test at 2 bars and it held for about an hour so they say it’s not the heater matrix, I’m at a loss now, any ideas please?
