Thanks for sharing that story Steve - might be a handy bit of intel down the track...
For a bit of perspective, one of my sons and his wife have a Subaru Impreza (not my fault). They are having a recurrence of "Check Engine" fault warnings.
First time it happened, their Subaru dealer told them that the cat was stuffed and needed to be replaced. RRP for the part was $4,500, but since they were nice guys they would only charge $3,000 (plus labour of course). Can't remember if this included new oxy sensors, but the excuse for the exorbitant price was that pretty much the entire exhaust had to be replaced, as the cat was built into it. They went ahead with the genuine part and (to be fair) it did fix the problem - at a price! (NOTE: I wasn't consulted about this, as I don't know anything about Subarus - apart from the one parked in the paddock.)
Three years later it's happening again, and the diagnosis (& price) is the same... However this time he has actually talked to me & his big brother (who also has Subarus). Turns out it's a common issue, & affects Libertys & Outbacks as well as Imprezas. Car is throwing a Catalytic converter fault ? club.liberty.asn.au
Solution (discussed in the above link) is to reprogram the ECU so that the Check Engine light does not show if the problem is worn-out cat - also necessary if a high-flow cat is fiitted. He has now downloaded the DIY diagnostic software, and purchased a diagnostic cable from eBay, so hopefully will start to take some interest in understanding what the problem is, rather than paying a lot of money (which he doesn't have) to make the problem go away...
Cheers
