I can confirm key fob electrics + 30c wash do not mix. I now need a replacement second key.
After speaking with VW they wanted to change me nearly £200 to provide a replacement key and code it, surely there must be a more cost effective method. As I have the key blade can I buy the immobiliser part (attached to the key blade) get that coded by VW then program the central locking fob with a new uncoded key off ebay or am I best getting both parts from VW?
