If the diaphragm in the FPR ruptures, fuel flows straight through the vac tube into the inlet manifold

Ah Yes ok. I was thinking along the lines of spring breaking causing drop in pressure as more fuel being returned to tank.

0537 VAG1551/2 Fault Code Number
Oxygen Sensor Control Limit exceeded,
fuel pressure too low or too high, intake or exhaust leak, defective ignition system component, intake air leak after air mass sensor, O2 sensor is faulty
00525 VAG1551/2 Fault Code Number
Oxygen Sensor (G39)
Sensor Wiring or Sensor defective Heat resistor in sensor defective, Signal wiring shorted to ground, Fuel tank empty, Ignition system component failure, air leak at mass air flow sensor, air leak in exhaust pipe before catalyst, poor ECU ground wire connection at intake manifold.
Symptom: Emissions not within specifications, increased fuel consumption, rich exhaust, spark plug fouling,
Carbon Monoxide (CO) percentage above 3%,
00513 VAG1551/2 Fault Code Number
RPM sensor (G28)
Open or short circuit, sensor malfunction
Defective sensor & cables, metal fragments on flywheel teeth
Symptom: Engine will not start, misfires, may stop running
After changing lambda probe... scan for codes. i wouldint say that rpm sensor is fine... i would take out and clean from the metal fragments on the tip.

Have a look at coolant temp in Vagcom, see if it agrees with reality.
