Hi All,

Sorry if this is posted in the wrong section, i only have use of a very slow computer at the moment as i am out of the uk and it takes ages to search anything.
I am wanting to buy the correct vag com cable and software for my 57 plate S5 4.2 V8, the engine management light has come on and i want to see whats going on, the light came on a few months ago and the local audi dealer said it was catalitic converter efficeincy issue ? no work was carried out but the fault codes were cleared and the car has been fine until now when the light is back on again.
So if anyone could point me in the right direction of what cable and software i require i.e part / serial number and best place to get these it would be much appreciated.

Thank

Rob.
