MY05 Legacy 3-litre auto: Dash lights came on this morning

Expect they will have flashed the ECU when they did the work explaining why no dash lights on. Probably wont find any fault codes now either so will have to see if it happens again.

Yes, the lights came back. This time I searched for my cable (and failed) so instead I plugged-in my bluetooth OBD connector and fired-up Torque on my new Nexus. It's reporting imminent catalyser failure so I chose to reset the error and pretend I didn't see it.

I only have 2 months left with the car. I'm not going to buy anything new but if anyone does have any 2nd hand cats, I'd entertain buying them.

I **think** (if I read it right) that all 4 sensors are providing feedback to the app, which means I'm more confident in the assessment that it's the cats and not the sensors. My uncertainty arose from the fact that there are actually 8 feedback lines from the sensors (all green). I'll make a note of what they are next time and write it here.

You have another option....Go decat SS exhaust system and a remap. Will be cheaper than buying new cats and give you some more go.

There is just one thing though i would recommend whatever you do....Run your car on 99RON...Always
