Over the Christmas period I've gone right through the car with a tooth pick, also given it a service etc, cleaned out them drains under battery, sorted leaky boot and a few other things. Today renewed the air filter and the box was drenched!! Full of **** and a slightly damp bottom end of filter!! Is this a common fault on the 1.9tdi? Does seem quite easy for water to travel across intake then DOWN into air box. Air box also fitted right above turbo, talk about keeping cool.
