I just bought this think a couple weeks ago thinkjing it was going to be an easy fix, oh boy. should have looked at what it takes to do these repairs. I suspected that it needed a powersteering pump but the steering is as easy as can be to turn, I ordered one and pulled it all apart because it did have a leak on the inlet for the pump. Turns out the pump I recieved was only 66$ but infact the exact mirror of the one I needed so I reassembled it only fixing the leak, but now im not so sure that its indeed the source of the whining noise. I took a vid im hoping someone could shed some light on it.. Thanks. The other issue it had was a low boost and limp mode which turned out to be a little e clip on the wastegate of the turbo. so far im in it about $4K after all the parts and taxes and managed to get all the lights to stop lighting up but the incessant whine makes me want to lose it.
