engine light !
« on: August 30, 2013, 06:47:56 pm »
hi all, I got in my car this morning and the dreaded engine management light came on. Car drove fine with no problems. Got it home and I plugged it in to one of those cheap code readers off ebay. Turned the light off and its been off since. The fault code was PO642. Does anyone know what it means and do I have to worry ? :confused:
 Its an 06 gti no mods.

Looks like a sensor issue.
Not sure which one though:

VAGCOM or VW diagnostics should be able to shed a little more light.
