I think my clutch/flywheel maybe on the way out? Judders on take off and make's a noise when I press the clutch pedal in. I've been looking online at clutch kit prices and there is 2 to choose from. LUK & Sachs, which one is the standard fit. I think its the Sachs one? Also how do I find out what engine code my car is? It is a 2008/58 2.0tdi 143 s-line. Thank you for any help.
