So, latest status:
Fuel line clamps are done.
Brakes are done, but we have a sticky nsf caliper which needs investigating.
The cylinder-specific misfires are caused by bad ignition modules. Cyl 4 (worst misfire) is driven by channel 2 on module 1. Swap them over and the misfire moves to cyl 3 - driven by channel 2 on module 2. Its also reporting random multiple misfires (which wasn't solved by replacing the fuel) so all channels on both modules are suspect.
The ABS module is showing 'return pump v39 intermittent' and looking at the data, the relay is chattering on and off. At the same time it and the TCU are also showing 'brake switch F implausible' - a very common problem which is also evident in my D2 and the C5 in the pic so three of those on order. I'm hoping the ABS controller is being confused by the switch and once thats fixed it'll stop chattering the relay. Hopefully...! The relay for the solenoid valves is also showing a problem though which is less hopeful. We'll find out tomorrow.
