Swap coil sticks from one bank to the other , if the codes stay on 5 6 7 8 sort of proves its not the coils , if it transfers ..... yes sounds like coils

Also when running in vcds data blocks you can see where cam advance is by means of degrees , if it has a cam sensor on every cam this is good because you could see all 4 cams ......some quad cam stuff only have a cam sensor on one cam per bank ....so for instance the exhaust cam could be stuck advanced but the sensor is on the inlet so the managment wouldnt see it .
Thanks, my thoughts were it wasn't necessarily coil pack related given that the fault started on Sunday with faults on advanced timing (P0024) and cylinders 5 & 8 but then went away after resetting and restarting car (and ran fine for a day and a bit) and then only came back last night with faults on three cylinders, all on the same bank as the over advanced fault.

Good call on the switching coil packs between banks, certainly better than 'guessing' at coil packs at £35 each! I'll mention it to the garage tomorrow and if they don't agree to try that I'll just get on my bike and wait until my local garage is free!
