Most 2016 Renault commercial vans used for refrigerated work have diesel dCi engines and manual gearboxes; the refrigerated box is usually an aftermarket or specialist conversion which reduces payload and can hide corrosion. Watch for diesel DPF/EGR issues if the van has done lots of short urban runs, and expect the refrigeration unit to need its own service history (compressor, gas charge and electrics). Commercial insurance is handled separately in Ireland and you should check DOE history and the vehicle’s stated payload/length (L1/L2/L3, H1/H2) so the conversion hasn't overloaded the chassis.

• Refrigeration unit: run it cold at rest, check temperature stability, service records for compressor and gas top-up, and any electrical faults.
• Load area and floor under the liner: look for corrosion, soggy panels or repaired patches under the cargo floor and around rear doors.
• Signs of overloading: sagging rear suspension, worn shocks, upgraded springs or evidence of past axle/leaf spring work.
• Diesel-specific items: DPF and EGR condition (black soot, frequent regen lights) — short stop/start work is hard on these.
• Manual-drivetrain checks: clutch bite and free-play (clutch replacement can be expensive), gearbox synchro feel and any grinding into first or reverse.
