guys! I have in the mk7 gti the following failures with very unstable idle and sometimes it shuts down. the faults that it gives are p0302 p0303 p0304 and p0016 but it does not get to turn on the light of damage and as it goes taking tenoeratura it goes better until it goes well of the whole. It could be the ignition coils. Or someone knows where the misfires come from. a greeting!
