Ok as title... Will start off by saying I have a 2000 ek4 VTI with a B18c using an apexi ecu. Problem I have is the CEl is on CONSTANTLY, does not blink even when I try and jump the service check connector and search for a code (which itself is a code zero apparently?). Although it will occasionally flash a few times while driving. Since the car runs and drives fine I checked every earth (all good) and out of curiosity checked to see if there was voltage going through the service check connector when jumped and there is NOTHING! So what the hell is my problem? There's clearly a fault in the wiring somewhere if there's no voltage getting to the SCC right?
