So I have a 2005 golf gt tdi 2.0l, upon acceleration my car judders and that through every gear. After it goes above certain revs the juddering clears. However on diagnostics it Said egr valve, so I replaced it, I have also replaced flywheel, clutch, starter motor, but it continues to judder. Any ideas please on my next move? Have spent nearly a grand sorting these bits out as this is what was advised and still not stopped the juddering need the right answer before I spend anymore money.also noticed a bit of white smoke upon start up. Thanks
