Just noticed this morning water dripping under the front n/s wheel arch. Lifted the bonnet and there's water dripping from a small rubber pipe low down on the bulkhead just above the gearbox. I also noticed the metal aircon pipes were frosted up just in front of where there pass through the bulkhead and the frost seemed to be melting and dripping when the engine was turned off. The water stopped dripping and the frost cleared when I turned the engine off and let it sit for a few minutes. as soon as I started the engine again, the frost reappeared on the metal pipes and the water dripped from the small rubber pipe again. Anyone help? It's not cooling system water but I suspect something to do with the aircon/climate control.
