Ignition Coil - Types
Brickwerks list three types for petrol engines, an early coil used (roughly) up to 1984, then a green label and grey labelled coil for later engines. The green label one is the most common of all for late engines. The grey sticker version has a higher secondary resistance and is capable of higher HT voltage. It is designed for long life plugs and extended servicing, and can fire a worn plug with larger gaps. It can be used to replace the green label type, however, it won't fit unless you also change the HT lead connection. The HT leads also need to be in good order otherwise the higher voltage will find a much easier route (ie to earth) if it is easier than that needed to fire the plug.
Ignition Coil (Early) up to 1984
Suits early T3 models with non pin type fitting (DIN) (ie similar to bays and beetles with no pin in the holes on distributor cap)
Test data. Primary resistance [between terminals 1 & 15] - .52Ω to .76Ω Secondary resistance [between terminals 1 & 4] - 2.4kΩ to 3.5kΩ
Ignition coil (Late) with pin type fitting - most common & green label.
Bosch unit with green label. VW No. 211 905 115 D
Test data. Primary resistance [between terminals 1 & 15] - .5Ω to .8Ω Secondary resistance [between terminals 1 & 4] - 2.4kΩ to 3.5kΩ
Ignition coil (Late) with pin type fitting - grey label. Bosch unit with grey label. VW No. 191 905 115 A
Test data. Primary resistance [between terminals 1 & 15] - .6Ω to .8Ω Secondary resistance [between terminals 1 & 4] - 6.9kΩ to 8.5kΩ
