Ignition wires in the aftermarket, much like spark plugs, are often sold incorrectly for the 2.0L engines.
The AEG uses 06A-905-409-L, the AZG, AVH, BEV use 06A-905-409-N.
I would only use OEM type (Beru is usually a good brand) wire sets, and they really can only fit one way. They come already laced in such a way as to be pretty darn impossible to put on the coil incorrectly.
