AUDI A4 2.0 TFSI 252 hp Allroad 2018 CATALYST REGENERATION.
The catalytic converter looked normal ...
No oil defect, no ignition defect so catalytic converter whole, not melted, not clogged, zero mechanical damage and yet does not work.
5 year old car, mileage of 150 thousand km. and the end of the catalytic converter, error P0420. This has become sort of standard and slowly ceases to be surprising. We have an era of austerity in the production of any car parts. We are replacing the cartridge with a new one. We used a cartridge with Euro 6 emission standard according to what comes out of the VIN number. A metal cartridge with a capacity of 600 cpsi with a diameter of 135 mm and a length of 100 mm. We cut in a band saw, tig welded the cartridge, zaspaw the housing and finished. The whole thing including shipping took less than 48 hours, the regeneration itself in this case is an hour of work and the rest is already in the hands of the courier.
