    With the crankshaft set at TDC, the cam pulley set half a tooth as needed on ADU and the markings on the chain sprockets should then line up perfectly.
    Based on recent evidence, I am not convinced of this. Needs more/better photos of the same ADU head taken at the same time both from the front and the rear showing the position of the cam timing marks and the cam sprocket with the G40 Hall sender shutter (without moving anything).

    AFAIK, the cam timing marks O-O are used to sync the cams, not necessarily at TDC. Once the chain is on and they are sync'd together, it doesn't matter too much whether that wasn't the crank-to-cam timing position.

      Your photo was too good to pass up so I "stole" it and used in this:

        Good that it could be of any use.

        I've now got the car running and everything seems to be fine. I have the same problems with hesitation during WOT once I get turboboost.

        Since this is not related to the topic I made a new thread here so this is not mixed

          Might be worth posting another thread about a specific fault to get a wider spread of members experience.
          Do you know whether the vehicle has been modified, i.e. chipped? If so do you know the origins?
          Has that altitude sensor value changed to something more accurate? I don't think it makes a massive difference unless of course as mentioned previously it is acting as that towing power limiting function. The value was suspiciously close to the published one!
