error code on S4 / B6

[1781cc]

OK, I am chasing an intermittent misfire on my S4, finally got myself kitted out with a VAG-COM install and a temporary cable (till payday and then will buy the real thing) but at the moment this is what I am getting...

VAG-COM Version: Release 409.1-US
Chassis Type: 8E - Audi A4 B6
Scan: 01,02,03,08,09,15,16,17,26,36,37,45,46,55,56,63,76

Address 01: Engine
Controller: 8E0 910 560
Component: 4.2L V8/5V G 0030
Coding: 0011711
Shop #: WSC 63351
2 Faults Found:
17983 - Right Engine Mount Solenoid Valve (N145): Short to Plus

16686 - Cylinder 2 Misfire Detected
P0302 - 002 - Lower Limit Exceeded - Intermittent

Any ideas if this is spark plug, coil pack or injector related?

thanks in advance peeps

Like the error code says - the "Right Engine Mount Solenoid Valve (N145)" is the cause of the first error, not the spark plug, coil pack or injector. Worth getting that sorted first to see if the second error is a "phantom error" caused by the first.

I have the car booked in for the first, but I have felt the misfire before when driving. I am not sure it is phantom, but have an LPG conversion on there makes me wonder if it is a petrol injector or LPG injector error? I will scan it again post Soleniod valve replacement
