Please note: When replacing the catalytic converter on vehicles manufactured before 03/2007, the DME data level must be updated.
1. Remove the adjustment probe.
2. Remove the control probe.
3. Determine the cutting line.

2) Mark the cutting line (1).
4. Cut off the exhaust pipe using tool 002210 and deburr the edges.
5. Unscrew the nuts and remove the catalytic converter.
Note:
- When installing, it is necessary to connect the new catalytic converter and the front muffler using clamp couplings.
- The joint should be in the middle of the coupling.
- Align the exhaust system and clamping couplings so that they are located at a sufficient distance from adjacent components.
- Adjust the position of the exhaust pipes (1) relative to the body opening.
- Tighten the clamping sleeve bolts.
