Car Detail: 2008 Subaru Liberty GT Tuned by STi
Well, over the last couple of days I noticed an irregular noise coming from my air intake (had an aftermarket Hyperflow installed). The Si Drive light and cruise control lights started flashing then the engine light came on static.
I took it in to a trusted mechanic who I have service my car to check it out and he cleared the code saying it was possibly a ghost code and performed a regular routine service. Anyhow, after driving from the mechanic, I noted the intake sputtered then the Turbo stopped completely. Poor car was driving like a Hyundai Getz

Anyhow I took it back to him and he apologised for not noticing this, but had assumed that was the regular sound of my intake. He checked the car over and said it is definitely the Turbo either gone or faulty somehow. And suggested I use my Warranty. By the way, I have no qualms with this mechanic, fully trustworthy guy and place.
Anyhoo, just now I dropped the car off @ Denlo Subaru in Parramatta. Let me just say, the service there at the front desk was horrendous. There was no 'warm' welcome / greeting. Basically made me feel from the start I had done something wrong. FYI I dont drive the car hard AT ALL. it mainly sits in 'intelligent' mode...I have a baby, like I said

So the lady next to him remarks "make sure you check the service schedule". Fair enough, standard procedure. But I find this and the way she said it very rude and quite disrespectful to say it in the way she did...IN FRONT of the customer.
Now, I had missed a service. Well 2 services were missed BUT 1 was combined and the other the mechanic didnt stamp the book. I have to look for the receipt when I get home. The guy points it out and says subaru may decline to repair since it has not been serviced regularly.
Basically what I am here for other than to express dissatisfaction with this place, is to ask if anyone has had a similar experience or warranty experience they can provide me with some pointers?
What steams me is that when I bought this car I noticed white, hardened, plastic like residue under the bonnet. I questioned the sales rep at the time and he just said "oh that is cleaning foam that has dried up" and when I picked it up he had the under bonnet protector replaced and the engine cover cleaned. In doing so, the limited edition badge for the STi tuned had gone missing. I had written to Subaru head office some time back about this and they said it couldnt be replaced but gave me a letter confirming the limited edition # of the vehicle.
Back to the point...any hints/tips how I would go about ensuring that this mechanic fault (alleged) is repaired under warranty? Or will this place basically charge me a diagnosis fee and then say Subaru have rejected my claim..
