have a VAG workshop bulletin for the DF, DG and SP engines which says that from Aug. 87 spark plugs with a single earth electrode are being installed in place of the three electrode plugs, this is in conjunction with a modified ignition coil which has a grey sticker. The recommended plugs for the green coil: W7 DTC 14-7 DTU N7 BYC grey coil: W7 DCO 14-7 DU N7 YCX The Primary Resistance for the green coil is 0.8 Ohm and the Secondary 8.5 K-Ohm and the Primary Resistane for the grey coil is 0.6 Ohm and the Secondary 6.9 K-Ohm This may apply to other engines but the bulletin was in the manual for the DG engine, a carburetted 1.9.
