PHIL7777

Hi All , First time posting , My fabia EPC light used to come on now and then and disapear for days on end, last week it came on and didnt want to go off ( the car goes into limp mode ) After a tow home from the AA , i had a auto electrician come out and he plugged his readers in etc and said it was coming up with throttle bodt error codes, he since then found a damaged wire which he repaired, but now says the ecu needs reapiring ? the car drove less than 5 miles and the dreaded EPC light came back on so its back on the drive way ! any one had similar before ?
