A friends wife was driving his 2004 New Beetle TDI and she heard a loud "pop" followed by loss of power. Upon inspection, he found the upper hose leading to the throttle valve had blown off. In the process, the "tangs" that the clips use to hold it in were sheared off. When we push it back on, the engine sounds fine but, of course, it pops off at about 3000 rpm.
I hooked up my Vag-com and downloaded the following codes:
17586-Liner O2 sensor; pump current: open circuit
16683-Boost Pressure Regulation: control range not reached
18628-Oxygen sensor B1 S1: signal too high (rich)
16497-Intake Air Temp sensor (G42): signal too high intermittent
18000-Altitude Sensor/boost pressure sensor: implausible correlation intermittent
16622-Manifold pressure/boost Sensor (G31): signal too high intermittent.
I'm not new to this but since my TDI's have had very little trouble (knock on wood), I'm not sure what is a problem and what is a result of the problem. I'm tempted to buy a new upper hose, put it on and keep running.
Any ideas? Perhaps an overboost situation caused the problem or the metal tangs were weakened and blew under normal pressure?
