Catalyst Failure Thread

[IdealRace]

If you have had a catalyst failure or catalyst replaced by the dealer - Can you post here with...

1) your mileage
2) build date
3) and if the catalyst was for the front bank (cylinders 1-3), the rear bank (cylinders 4-6), or both banks?
4) what CEL's did it throw & what symptoms did you have?

The cylinders are numbered 1-6 from the front to the back.

Mine were apparently replaced before I took possession with 35km on the unit. Tech needs me to bring in the truck to do a software update regarding the new cats now. No CEL or issues yet even without the software update.

Can you ask the technician to write down what software version you came from and what sw version you updated to? Thank you for sharing!
