My 58 plate 350Z GT recently died on me at just under 180,000 trouble free miles. Local Nissan dealer diagnoses ipdm & engine compartment wiring loom damaged/burnt out due to water ingress. I am quoted £1,700 to repair. Also, they tell me the part must be custom made in Japan, so i anticipate a long wait! Has anyone else come across this, and how reasonable is the price?
