Hi all, first post so please bear with me if im annoying.
Vauxhall Vectra C 1.8 club, tried clearing the ecu by switching
ignition on and off 25 times as recommended elsewhere, didn't work!!
However, what it has done has made my car unable to start, im now
getting the car with the spanner icon thru it! Ive had a bit of a read on
here and came across the thread on how to get fault codes via the ignition/pedal method. ive now got a few fault codes, but how do i determine the prefix letter, because there are several of the same 4
digit codes but with a different letter prefix. i.e 1405 could be prefixed with, B, P or C.Is there a way to tell??
