Car: Polo GTI 2000, Approx 73k, recent dealer service, just put new OEM plugs on to try & solve splutter (may need HT Leads yet - look in good condition).
Symtoms:
1. Air Filter soaked in oil from the return pipe off the engine
2. Bad Splutter / hesitation when driving. This usually appears when you need to pull away, and you're currently moving (no specific gear - usually all, but very spiradic)
