Ignition Coil - Types
Edited by CovKid: 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 1986-1990 vehicles. The green label one is the most common of all for late engines. The grey sticker version is a 'punchier' version although that does not mean you'll get more power over a green one. It just has a fatter spark and the leads will need to be in A1 condition.
It has a higher secondary resistance and is capable of higher HT voltage. This coil is designed for long life plugs and extended servicing, and according to BigHerb can fire a worn plug with larger gaps. However, it is not a direct swap/replacement unless you also change the HT lead connection. The HT leads also need to be in good order for this type of coil otherwise the higher voltage will find a much easier route to earth than through the spark plug - ie potential for arcing increases. In most cases, the green label variety is the correct one if you have a late engine but a grey sticker one could be fitted if the above points are noted.
Ignition Coil (Early) up to 1984
VW No. 211 905 115 B
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 - Green (Later type 1986-90) with pin type fitting - most common type for late engines.
VW No. 211 905 115 D
Bosch unit with green label.
Test data. Primary resistance [between terminals 1 & 15] - .5Ω to .8Ω Secondary resistance [between terminals 1 & 4] - 2.4kΩ to 3.5kΩ
Ignition coil - Grey (Later type 1986-90) with pin type fitting - extended servicing type.
VW No. 191 905 115 A
Bosch unit with grey label.
Test data. Primary resistance [between terminals 1 & 15] - .6Ω to .8Ω Secondary resistance [between terminals 1 & 4] - 6.9kΩ to 8.5kΩ
Read note above for differences between green and grey stickered types. They are not a straight swap. Brickwerks advise that you check to see what colour sticker is on yours before ordering.
