[BiturboS4] S4 Blown Turbos - Update - Audi's Preliminary Diagnosis

[California Fields]

[ Converted text/html to text/plain ]

JY, whether you have OEM clamps or twist-ties or whatever on the BPV hoses
makes no difference. Don't let Audi make that as an excuse. As long as the
hose is clamped down on the tube, no pressure is escaping.  Tell them you took
out your BPVs once to inspect them...and you put them back with a different
clamp. That's not illegal!

>Again, the Service Mgr said "Audi's policy is to go

>
>Thus, I have 52k mi on my S4 - so Audi considers my

>I understand this but I still have a personal problem

>I left my S4 at the dealer and said "that I would

>On another note, I replaced the Stratmosphere DVs with

>they noticed that the DVs had been swapped out -
>beause the OEM clamps on the Bosch DVs cannot be

>So, no OEM clamps on the Bosch DVs leaves one open for
