I'm rather concerned about filtration given the conditions my vehicles operate in - air filters are replaced at 10,000 km (6,250 mi) internals religiously. That being said, I double checked to make sure everything is securely fastened.

Definitely not sand. If you rub the stuff between you fingers, it dissolves effortlessly.

Same in Euro and the US. Could he be wrong? Possibly, but he seemed quite sure of this. I wonder if you checked your air filter?
Thanks for the confirmation.
This is rather peculiar to say the least - nothing has changed over the past 3 years other than COO.
