Have a 2009 Outlander 2.0d (Volkswagen engine). Done 135,000 miles. New clutch fitted recently. When road tested very smooth for first 5 miles approx then whole car starts juddering when revs between 1500 and 2500 in any gear. Mechanic initally diagnosed transmission wind-up. After seeking advice dual mass flywheel also changed. Fault still present, Many people asked for advice, some saying they have heard of it before but not what the cause / cure was. Anyone able to help?
