I have a 2007 R320 cdi, purchased it used and now the turbo actuator is not working. It looks like the turbo had recently been replaced but the actuator not. Turbo is numbered 764809-002, actuator is 730314 6NW 0090228. I'm not sure if it the right actuator, Is there someone on the forum that can confirm the actuator part and tell me what gear code this turbo needs? There seems to be a huge variety of similar parts on ebay. Thanks and happy holidays to all!
