reading fault codes

Is it possible to flash up the fault codes like you can on some other cars?

reason I am asking is took the fabia I just bought into the local dealer yesterday to do a service and check it over nad they say it has got several stored codes, the engine managment light hasn't flashed at me since I have had it so can only presume they are from when the previous owner had it and had a problem with the throttle peddle ( which was replaced on warranty)

so I was thinking of leaving the battery off for a while then going for a spin and checking after to see if any fault codes are logged

any other idea's?

thanks guys
