- Equip Scissor Lift Table (VAS 6131 A) with Support Set (VAS 6131/10) as well as 3 Support Elements (VAS 6131/10-12) as follows:
- Position support elements from (VAS 6131/10) at left on engine as shown in illustration.
- Position support elements from (VAS 6131/10) at right on engine as shown in illustration.
- Twist spindles of attachments upward far enough until all support pins make contact at support points.
- Tighten base plates for support elements to 20 Nm on Scissor Lift Platform (VAS 6131 A).
- Disconnect electrical connector - arrow - on Engine Speed (RPM) Sensor (G28).
- Disconnect electrical connectors - 1 - for Heated Oxygen Sensor (HO2S) (G39) and - 2 - for Heated Oxygen Sensor (HO2S) 3 (G285).
- Touch the transmission housing (when not wearing gloves) to discharge the static electricity.
CAUTION!
• Only touch Mechatronic electrical connector after you have discharged electrostatically on a grounded object, for example, skin contact with the transmission housing.
• Never touch the connector contact in the 16-pin connector for any reason because the control module and Mechatronic could be destroyed by static discharge.
- Disconnect electrical connector at left on transmission by turning the twist lock counterclockwise - arrow -.
- Free up electrical wiring.
- Remove right oxygen sensor connection heat shield from transmission - arrows -.
- Remove oxygen sensor electrical connectors - 1 through 6 - from bracket on transmission.
- Disconnect electrical harness connectors.
- Remove bolts - 2 - and - 3 - and remove oil dipstick guide tube upward - arrow -.
- Loosen hose clamps - 1 - and - 4 - and remove left coolant pipe from coolant hoses.
- Remove bolt - arrow - at left exhaust tract strap.
- Remove nuts - arrows -.
- Remove nuts in - 9 to 1 - sequence and remove left front exhaust manifold with catalytic converter.
- Remove nuts - 6 to 1 - in sequence and remove left rear exhaust manifold with catalytic converter.
- Remove left drive axle heat shield from transmission - arrows -.
- Remove bolts - 2 - and - 3 -.
- Loosen hose clamps - 1 - and - 4 - and remove right coolant pipe from coolant hoses.
- Remove bolt - arrow - at right exhaust tract strap.
