New (to me) 200q20v not running anymore :((((

[Mihnea Cotet]

Happy Easter to all of you who believe in God first :-)

Next, I need your help because the new to me 200q20v that I have bought
yesterday doesn't run anymore...
I was climbing a slight uphill on full pressure (well, about 1.7 Bar on the
digital display) in second gear, and when I shifted in 3rd at about 7000
RPM I heard something like a "whoosh" or popping kind of sound and the
nada! 1.0 Bar on the display, won't start again, nothing, it's dead. A few
minutes later I've pulled the codes and got the following:

2342 O2 sensor ...air leak at the MAF, Ignition system component failure,
etc...
2341 O2 control limit exceeded, intake or exhaust leak, efective ignition
component, intake air leak after the MAF, etc...
2113 Hall sensor
2111 RPM sensor (normal because the engine didn't start, IMHO)
2121 Idle switch (IMHO it seemed to be okay as it DID do the clicks when
opening and closing the throttle body)

Any ideas anyone? I think I've busted a pressure hose as would seem to
confirm code 2341 but what does the Hall sensor have to do with all this? I
hope it's not toast....in case it is toast, can I use a NA 5 cylinder Hall
Sensor in the 3B's distributor? What does oil inside the dizzy mean? Bad seal?

As always, thanks in advance for your answers and much appreciated help, I
need help pretty urgently as I'd need to drive the car before my coupe
quattro has its suspension rebuilt....

Regards from Belgium,
