Ever since buying my PD170 a few months back the Idle has been really rough, had a play around with VCDS to find my 'Torsion' value for the cam timing is 4.8. In order to get this as close to 0 as possible the timing needs to be adjusted. http://www.myturbodiesel.com/1000q/multi/PD-adjust-Idle-TDI.htm I found the above guide useful and decided to give it a go however my engine has a twin cam and not sure what to do? Do I adjust one or both? Any help would be appreciated...

Yea already had the kit, I'm just not sure with it being twin cam

how easy is the PD170 to re-time?

To be honest I'm not sure what needs doing?

Had a search of the web, I'm sure my torsion value shouldn't be that high?

Sorry to bring this up guys, I have a PD170 running lumpy on idle. Torsion Value = between 4.85 and 5.25 (Measured from VCDS, Group 4) A sample of of Injection Quantity (VCDS, Group 13) I would apreciate it if someone could take a look over these figures and hopefully point me in the right direction.
