Cheers guys! The actuator on the car is 06N145655, the clips look like just C clips but an odd shape that fits through the arm to grip the ball joint.
Absolute pain to find at the moment, probably one of the most expensive clips to lose 😅
Ive messaged a few car breakers and tried local scrap yards but no luck at the moment.
The search continues...
Driver System Fault warning, have a look under the bonnet low and behold Wastegate Actuator arm isnt connected to ball joint on the Actuator itself.
Closer inspection the clip holding the actuator arm to the Actual actuator itself is no longer there!
Spent all day going to different local garages, turns out the clips cant be purchased on there own and come as part of a whole new Actuator quoted (£439).
Is there any place that would be selling just the clips or breaking A4 2.0 TFSI (B9) that could be recommended to purchase the clip?
