Hi
I bought a C63 in June (2014) the dealer said it had secondary cat delete and all was well
I took the car to a dealer who asked if i wanted gearbox and engine update i agreed
Now I think the car had been remapped because it feels slower now and the CEL light has come up, i can reset the code and after a couple of days it comes back on (PO420 and i think PO430)
Now im thinking that perhaps the primaries have been gutted , is this possible? Looks like the primaries are still in place
Car doesnt sound insanely loud
