pulled over and opended the air box as the amount of rain we had was collosal. I had to pull over for 10 minutes as I couldn't see out the Windscreen. Anyway water seemed to have found it's way into the air intake even though I have a snorkel fitted. (points rearward too). The filter was sodden too. Looks like I may have a leak in the intake somewhere or, drive slower when its raining.
