Catalytic delete is available (off-road only).
Rear O2 sensor delete is not available for later 1.8T and 2.0T TFSI and TSI with SIMOS engine control units (as opposed to Bosch MED9 and MED17) and exhaust manifold built into their heads. It's because they depend more heavily on the rear O2 sensor to ensure a more accurate AFR. This is consistent with our desire to maintain OEM-level reliability and smooth drivability, especially at high performance.
