Removing and installing bracket with retaining washers:  
Note  
Depending on the equipment level of the vehicle, a securing  
clip β‡’ Item 9 (page 539) for the bracket of the catalytic convert‐  
er may be installed. When the vehicle Β»hits the groundΒ«, the  
retaining washer prevents the catalytic converter from slipping  
out of the bracket. The retaining washer can also be retrofitted  
if necessary. For retrofit parts, refer to β‡’ Electronic parts cata‐  
logue (ETKA).  
To detach bracket from catalytic converter:  
– Remove connector for Lambda probe 1 after catalytic con‐  
verter -GX7- from retainer, disconnect it, and lay electrical  
wires to one side.  
– Loosen clamp -1- for catalytic converter -2-, and push clamp  
onto turbocharger.  
– Remove noise insulation β‡’ General body repairs, exterior;

insulation.

– Unscrew nuts -2-.  
– Unscrew bolts -arrows-, and lower catalytic converter as far  
as possible.  
– Drill out pop rivets β‡’ Item 10 (page 539) , and detach lock  
washer.  
– Detach bracket from catalytic converter.  
– Check if pop rivets can be inserted into mounting on catalytic  
converter. If necessary, widen holes to 7 mm with a drill.  
– Fit bracket -1- to mountings on catalytic converter.
