    Thanks @m_c . Actually it did show up on the scope but I missed it! Looks lovely at 3250rpm just 10ms before the injectors shut down! :

    BUT I missed that it only had an amplitude of 7v - should be 15-20v at idle and scoping it at 3250rpm shows an amplitude of around 100v. If I can't get a clean waveform off it tomorrow I am going to back it out a smidge as I did put it in until it hit - the Jag workshop manual says until it hits.

    I have live data but the scan tool's graphs leave a lot to be desired!

    this is why I gave up working on any BMW newer than an E46, then I retired, imagen trying to make a living as an independent specialist working on "modern" cars, I even had, still have a dealer DIS, size of a fridge freezer, works on BMW's up to around 2009..... I used to say 2 days to diagnose it, 1/2 a day to fix it 4 days to sort out all the sh1t that all the other garages had done to it trying to fix it before it got to me...……………...

    one job I remember was a failed radio on an E65 seven series I think, tried a similar radio from an E60 five series, it worked, told the owner to buy a used one from ebay, fitted it, did not work, ended up with the interior mostly stripped out, turns out that the correct radio "needed" to talk to the heated rear screen that doubles as the antenna to check it was awake and ready to work, fault turned out to be a damaged data wire from a bumper parking sensor that was shared with the rear screen, the guy did not mention that the rear parking sensors were inop as he did not care, so often when we finally found the cause of a problem and presented a large bill the customer would say, Oh yes I remember that the radio went off with the parking sensors when I reversed into a post...…………..

    Annoying turbo whine demanded some action.

    Acquired a new core and split the turbo housing. Lots of play and the bearing sounded really bad. Think I may have found the problem..

    The bit seems to be sitting on the top of the cat !

    I also backed off the crank sensor a mm - performance noticeable smoother - wave form still; crud a 3500, new top quality sensor needed I think.
