VW Caddy 1.6 diesel van white

Good afternoon I have had my Caddy Van for about three years was bought for a special project that never took off. It’s only done about 100 miles each year not using it has caused an injector problem that comes up on a code reader saying electronic problem on injector one also bonnet cable has snapped. I bought a new bonnet cable but not fitted it the van is for sale good condition with 152000 miles needs one injector looking at and the brand-new bonnet cable fitted has got MOT and is taxed on the road.
