Right then guys and gals, had an odd intermittent stutter the last few weeks and have just discovered that the rubber gromet on the pipe circled wasn't sealing properly, can anyone tell me what it does and whether it could cause the issue in question?
Just as a side note, the following parts are brand new:
Diverter valve
coilpacks
spark plugs
just been serviced
2007/57 gti dsg
No lights coming up on dash
had codes read before came up misfire, hence coilpack replacement
