2003 passat 1.8t awm 126,000mi b5.5 Rough Idle a few minutes after starting. Codes p0300.0301, 0302,0303. Cleared them still reappearing. VW replaced coils, I replaced spark plugs. Still same results. Checked for vacuum leaks. Found cracked pcv oil breather hose. Did not install yet. Could this be the problem. Have not checked the pcv valve under the manifold yet. All other hoses seem ok. Am also getting suction when I remove the oil filler cap when running, could that be the pcv valve and the cracked hose or am I missing something. Dave
have the same problem?
