2009 BMW 335 N55 Engine

Throttle valve housing must be remove. Purge hose removed on throttle and 3C hose introduced behind throttle plate. Reinstall throttle.  The Valvetronic connector will also have to be removed for maximum valve lift to achieve proper manifold vacuum for cleaning. Once throttle is assembled with 3C hose and Valvetronic connector is unplugged, begin the 3C cleaning. Once complete, replace purge hose on throttle and reinstall Valvetronic connector when complete.
