Just done some checking with ETKA over the history for these coilpacks.
07K 905 715 was dropped on 01.03.06. Replaced by 07K 905 715C
07K 905 715C was dropped on 01.03.09. Replaced by 07K 905 715D.
07K 905 715D was dropped on 01.05.09. Replaced by 07K 905 715F.
07K 905 715F is the current part number.
The engine codes these were fitted to were BWA, BWJ, BZB, BWA1, CDAA & CDLA.
Hope this may help.
Just checked the V5 and I have the BWJ engine. Think I may check if they need replacing too.
