Hello, my Venga 1.4 l CVVT Bj 2010 has a total failure of both catalysts after a little 68000 km. From research I know that the same catalyst has also failed with a Rio, at about the same km performance. There were no warning lights in the run-up to the failure and no error indicator in the OBD. Failure was logically only noticed about the performance loss. This has also expired with the Rio. There are more users with the same exclusion here in the forum. len? Has no warning light lit up with you either and was no error stored in the OBD? Thank you in advance for feedback
