I have a 2006 VW Jetta BRM motor with 174,000 miles and I just recently had the cam replaced with a BEW reprofiled cam, new timinge belt kit, a new single mass flywheel installed, and injector 4 replaced with a rebuilt injector. The hard start issue has disappeared, but the car is still idling rough at times and stuttering upon acceleration. I am leaning towards pulling the injectors and having them rebuilt. I am new to VCDS and need help interpreting all of the following information. Please let me know if there is more info I should include in the post. The torsion value is at 0.0 and the guy who did all of the work is a trusted TDI mechanic, but lives three hours away and I can pull and replace the injectors myself. Great site and thanks for the help.

Update

I forgot to mention that I have replaced the fuel filter and ran 1L of diesel purge through the injectors. Any help in diagnosing the problem would be much appreciated.:)
Thanks,
Chad
