Removing Oxygen Sensor Downstream Of Catalytic Converter On Cylinder Bank 1
WARNING: This page is about a different variant/trim than selected.
CAUTION:
Risk of damage to sensor if handled incorrectly!
→ Do not remove the plastic cap on the thread until just prior to fitting the sensor. The grease used on the thread must never get into the connector.
→ Protect sensors - before and after fitting - against mechanical shocks.
→ Sensors that were dropped on the floor must not be used owing to the risk of a broken ceramic insulator.
→ The cables must not be twisted or kinked when the sensors are screwed in. Avoid pulling on the cable and connector.
→ Cleanliness in the housing of the plug connections is of utmost importance for the oxygen sensor to function properly. Particles of dirt can impair the function of the sensor. The connector must therefore be protected against any and all types of soiling.
→ Sensors with a soiled or damaged connector must no longer be used.
→ Protect the cables and connectors when carrying or moving the exhaust system with the sensors already fitted.
→ High-pressure cleaning equipment must not be used in the area of the sensors and plug connections.
→ Contact and corrosion agents, e.g. Stabilant, must not be applied to the plug contacts of the oxygen sensors.

CAUTION:
Hot components
- Risk of burns
→ Let hot components cool down.
→ Wear personal protective gear.
NOTE:
Incorrect handling of oxygen sensors
- Damage to oxygen sensors
- Different exhaust emission behavior
→ Do not remove the plastic cap on the thread until just prior to fitting.
→ Protect oxygen sensors from impact of any kind.
→ Do not kink or twist the cables when screwing in the sensors.
→ Do not re-use dirty or damaged components.
Information
- Pre-treat corroded components with anti-rust agent or heat.
Information
- > 9866 - Support can be fitted instead of the torque support for better access in the engine compartment.
- Engine can then be moved to the left or right by turning it at the > 9866 - support hexagon (SW 17).
Information
Modification of special tool 9866
- The special tool > 9866 - support must be modified for use in the Panamera G2.
- Saw off individual components at the dashed lines and de-burr them.
- Change the labelling of the tool to 9866/2 -arrow- using numbering stamps.
- It may no longer be possible to use the tool on other vehicles.
- Purchase another special tool > 9866 - support if necessary.
- This measure applies temporarily until the special tool > 9866/2 - support is available.
