Hi All,
I've had engine warning light come on and my Cruise light flash repeatedly.
I checked my ODB2 finding P0420 - Powertrain - Catalyst System Efficiency Below Threshold (Bank 1) fault.
My local garage advised that this could be the lamda sensor failing rather than the cat, so I replaced that and cleared the fault code.
Subsequently I've had the engine warning light come back on, and the fault code return, so having spoken to my garage again they've advised the cat needs to be replaced.
What are my options here? The car has sone 105k miles and I'd like to get another 100k out of it, it's in very good order generally.
I don't want to fit a cheap aftermarket cat, if I replace it I'll use an OEM or premium aftermarket option, which doing some research is going to cost me around £500-£600.
The garage has suggested I de-cat the car until the MOT, then see if it fails due to emissions, and if it does replace the cat at that point.
I guess my questions are:
Has anyone here de-cat'd their Outback 2.5 and had it pass an MOT?
Is there a way to permanently clear the fault code that will be caused by the decat?
I'm happy to spend the money on a cat if I need to, but I'd prefer to spend it on a tow bar and lift kit. 😂
Any advice much appreciated.
