Hi guys

Car has been running rough, smells badly of fuel, lurches as it goes up in speed. I had the EPC light on for a while, cleared all the fault codes with VAGCOM, drove around for a while, came back and scanned again. Now the only code is as follows (with no CEL lights).

Address 01: Engine Labels: 06F-907-115-AXX.clb

I have recently installed the 034 HFC, but I think that may be a coincidence. The BSR tune doesn't disable (or manage) the O2 sensor and I haven't installed the mini-cat (034) for the rear sensor.

Is this simply a new pre-cat 02 sensor required in your educated opinions, or should I test something out first before dropping $350+ on a new sensor?

Thanks guys

Swap your cat back, clear codes and see whether anything changes. If it all goes away then you can rule out the sensor as faulty.

Thanks for your response, I have bought a new O2 sensor pre cat and will see how it goes. Ill update the thread.

New O2 sensor fixed the issue. Thanks
