actuator set up
 

im fitting a new second hand actuator to my a4 1.9 tdi b5 can anyone tell me how the rod is set please? any other info would be appreciated as im new to Audi's. think its a 90 bhp but open to any info anyone can offer. it has no red 'i' so presume its the base model/entry.
thanks for any bit of help with me being new to audi :confused:
