Hi folks The C43 currently has a small exhaust leak due to join at left front cat and front/ mid section - bolts/nuts are disintegrating - see pic Part number 20&29 are required to join part no 5 (front cat and pipe) to front/mid section - My local MB have emailed me stating there are 3 Part numbers for one part and 2 for the other - can anyone confirm which parts I actually need ? Have enclosed their systems diagram below with descriptions
