I have been told that I need a new DMF in my golf. The quote for work was $1500 in parts and $700 in labour.

VW Golf 2005 - 1.9 tdi
BKC engine
6 speed manual
Stock tune/Daily use

Does this quote sound reasonable? DMF Clutch and Flywheel kits can be bought from Darkside Developments and shipped here for about $700 - would the mechanic need any other parts to complete the work? Seems like a ok way to save $700-$800?

Thanks for your advice
