I have this exact same car (97 outback 2.5L) and I've had multiple late 90s subarus over the years, and it can be very annoying to complete the drive cycle or know if the emissions check of the ECU is working as intended or just taking its sweet-ass time doing its checks. As /u/bobbysenterprises mentioned:
> What exactly is considered a drive cycle seems to be protected closed source information.
is fairly accurate. basically you need a combination of low speed driving, stop and go, idling, high speed driving, acceleration, and deceleration. You could probably complete the cycle in an hour or so of just aimless driving, with the intent to try and lot of varied driving.
Here's a tip, invest in an OBD2 code reader that can tell you the system readiness state, I have one of these which can do this (as well as read/clear codes, etc). At least this way you can drive around, check the readiness state, and know if its working or not. Here's a slightly fancier version with a color screen
this one has live data from the car, $33
This one only reads codes but gives you the definition $18
This just reads codes, nothing else. $15
If they quoted you $3200 its probably a professional scan tool, those can read anything going on in the cars computers and even take control of stuff too. If you just want to see what's causing the check engine light and of the above 3 would work.
this last one is more expensive, but it can read obd2, abs, and air bag codes. Pretty much everything the big $3k unit does.
For the SES light, you need a cheap ODBII cable. Connect it, see what the code says, take a picture of it on your phone. Go up and google it on e90 post and see what it could be. Take to AZ to read the code, but get your own on Amazon as you'll need it more. I have this one.. Reads the codes and clears them for me.
Did you buy it from a dealer or private party?
Bimmer Repair Shops, and simply enter your zip. Call around for quotes.
>ntion that there is a light of a half full motor or transmission symbol, which doesn't go away
This is your HPFP, take it to the dealer as this should be covered to 120k miles. This happens to me from time to time, but I'll reboot and it'll be fine for another 6 months, and then it'll come on when I'm driving hard. Just bad timing really. I'd assume it would be free as it's under warranty, and you are at 38k miles. But have them quote you for sure. Warranty Info. There's another that covers you to 80k miles, and may be the turbos. If all else fails, you should notify the dealership where it came from. Worst case, and absolutely worst case - you should get your insurance involved, or just have it towed back and write a letter for money back. But you're not there at all.
Let us know what happens. TL;DR - dealership, talk to the service advisor about the HPFP. I've always heard the HPFP needs to have the SES light on. Have them diagnose for their fee, and decide from there. They should cover everything for you.
Get yourself a proper OBD-II scanner, either like this one or this one, that will read the codes properly. Once you have the exact code numbers, if the device won't tell you what the code means, you'll be able to Google it.
This is the one I have:
