I finally found out what the clicking noise possibly is, i ended up taking my car to the stealership and they took a look at my cv axle and every is fine. then i took him for a drive to show him the noise and he said it might possibly be my diverter valve and i have noticed a loss is power, his going to test my valve whenever i take it in for free to let me know exactly but his 99% sure that it is that, and the seal broke causing loss in power and the noise. so now im trying to decide which dv valve to go with he recommended the TT225 which from what i read is pretty good cause its meant to take more pressure, im looking for one that will give more performance and a little louder turbo noise but at the same time being a reliable one. so im not sure if i should just go with the TT225 or get a different one.

theres all different types. Forge 007 forge 004 forge spiltter apr1 its really up to you.

 

That Synchronic one certainly looks neat too, but I haven't really heard much of anything about people actually using it. Clearly the OP should be the guinea pig and report back to the forum on how well it works with Audis.

 

good call ^
