The 2008 4/4 was fitted with horrid perishable rubber windscreen washer tubes that sit immediately above the circuit board. Mine leaked and were quickly replaced with neoprene tubing. I recommend double checking if your tubing is of the black rubber type. If the car is rarely used in the wet you may not notice any leakage for a long while but then get cought out a few years down the road.
Mentioning this as a possible cause for the circuit board failure.
