Why do we go through these cycles - a while ago we had lots of posts on Mafs which have now dried up, then loads of posts on windows /Cl wiring problems, then key/lock programming problems, then wiper problems, recently petrol starting problems- relay 27/30/167 it seems they come in waves as if Guests see the subject come up and decide to register and ask their variation until that subjects done to death. This pattern does seem new though, I've not noticed it before this year. Anybody else seen this before (excluding old chestnuts such as aux heater, Aircon, spare wheel winch)
