Hopefully nothing serious - after an hour of diagnostics, they've told me a Lambda sensor has failed (they said exhaust but were not specific, i suspect pre-cat). They are replacing it for me. And to be fair, they've been pretty good with me as well - drove me to work in another City, and will drop off a car at work before the end of the day for my use over the weekend.
Am still annoyed the car broke in such a short period of time, especially as I would have thought this would have come up during its pre-delivery inspection / road test as well (my suspision is it did, and they cleared the fault! perhaps just me being paranoid), but I guess the way they are dealing with it now is the important bit, and thats been pretty faultless...
