went to merc with a dueliner i want to buy. its a 04 plate with engine management light on. they plugged it in for me whilst i went to shops. time i got back techs were gone.
got a print out of all faults and dont know what they are.

2514-001 component R39/1( vent line heater element) does not function properly short circuit to positive.

2025-002 the signal from component b28/1 (pressure sensor downstream of air cleaner) is faulty. short circuit to ground or open circuit.
