Hi all,

I am after some guidance on the following codes scanned recently on my Treg.

I have the wiring diagrams and will get around to do some testing next week, weather permitting, but would like to know if the faults listed are likely to be wiring or genuine component faults.

For starters, the brake boost pressure sensor, cam pos'n and eng speed sensors, all appear to share the same ground/screen.

The warmup cat faults happened simultaneously a month or so back and the car has only apparently done about 72K miles.

A bunch of CAN bus faults exist and may or may not be related.

My primary focus though, is extinguishing the MIL, as that'll be a deal breaker when I decide to sell the car for something more pedestrian.

Thanks in advance for any help.
