For some days I have noticed a wet patch on the drive. Looking underneath the car just to the rear of the engine is a drip. So I collected the water and sure enough it was water and clear. I even tasted it and it has no chemicals in it. I lifted bonnet and that chassis beam at the bottom and to the back of the engine has quite a bit of it sitting on it as the beam as it is concave. Not having washed the car for a while, I cant figure where it's coming from. The washer bottle is topped up and the level is unchanged. The engine coolant is at the same level too. Is it possible the water is leaking from the air con system ?
