The main problem with the relays themselves is the Air Pump relay ( #5 ). It feeds power from the 40 amp fuse to the air pump on the front of the engine at initial startup for approx 30 seconds. The contacts on this relay tend to burn much faster due to the higher amp load.
I ordered, and received 12 of these relays, but found it very hard to remove the old relays from the board, so after successfully replacing only the #5 relay on my spare board, I gave up.

The problem with the board itself is the 3 solder points originally addressed, I'm not sure if the issue exists due to mechanical vibration, or fluctuating temperatures.

See this thread for pictures of the relays, as well as the 3 solder points on the board :
