Question about 2000 Volkswagen Beetle
Diagnostic code states PO134 and PO135
P0134 means that no activitiy (function) is detected in the sensor. P0135 is an 02 sensor heater malfunction. Basically, it sounds as if your O2 sensor is dead and needs replacement. Being that you state it's the 1,1 sensor, you're talking about the primary, or pre-catalyst, oxygen sensor. This is the one closest to the engine, before the catalytic converter.
