Since I don't have a 40, I can't help you. However, my wife and daughter both have a VW TDI and I use K&N filters. To clean, I'll spray it with a filter cleaner (every step is for both sides), wait 10 minutes, rinse with low pressure cold water. After it dries, thoroughly coat it with air filter oil, wait about 20 minutes and install.First time diesel owner and want to clean the air filter. The right way. Help.
