Could be any number of things - did the person who cleared the codes record what the faults were? If not, then you'll need to wait till it goes again, then get the codes recorded.

The codes your friend cleared would have been invaluable information for diagnosing exactly what was wrong, but assuming the codes were blindly cleared to turn off the warnings I'm going to speculate that the most likely candidate would be the "lambda sensor". At £23 on eBay for a cheapy one, and assuming your frined that cleared the codes can turn spanners, I'd say it's worth a punt?

I wouldn’t go replacing any parts without at least some diagnostic info unless your happy to throw money away, there are loads of things this could be.
