DL501 S tronic: test for jerks when pulling away and on downshifts. Ask for oil records (every 40,000-60,000 km). A scanner should show P189C or P17BF if the fault is stored.
Suspension: on a lift, check wheel bearings, bushes and dampers for play and leaks. On air suspension, check ride height; a scanner shows height sensor faults.

Turbo (needs a scanner). Read boost faults and check the vanes. Bad: power loss, whistle or smoke.
DPF (needs a scanner). Read soot and ash loading. Bad: frequent regeneration or high oil level.
Intake manifold (pressure test). Pressure-test the cooling system. Bad: coolant loss with no puddle, worse under load.
EGR cooler (pressure test). Cap the cooler hoses and repeat the test. Bad: it holds only with the cooler bypassed.
AdBlue and NOx (needs a scanner). Read NOx sensor and dosing faults. Bad: an emissions warning, a restart countdown or crystallised AdBlue.
Water pump and heater. Start cold; heater must blow hot. Bad: weak heat, wandering gauge, dried coolant.
Oil pump drive (needs a scanner). Listen for a rattle at idle and check for oil-pressure codes. Bad: a red oil-pressure warning.
Belt and pump invoices. Ask for dated belt, pump and thermostat invoices. No record means budget for a belt job.
Recall check. Enter the VIN in the official recall check. Bad: an open 23Z7 campaign on a T6.
