DI­AG­NOS­TICS

Car Mechanics (UK) - - Servicing from Home -

Elec­tron­ics play an in­creas­ingly vi­tal role in mod­ern cars. De­pend­ing on your make and model, cer­tain main­te­nance tasks will re­quire a di­ag­nos­tic tool ei­ther to carry out the pro­ce­dure, or re­set the dash­board ser­vice in­di­ca­tor.

On older ve­hi­cles, not re­set­ting the ser­vice lamp may not have con­se­quences, but it’s es­sen­tial for newer cars, or else cer­tain func­tions might not work cor­rectly. For ex­am­ple, a car that thinks its en­gine oil is still old might not per­mit ac­tive re­gen­er­a­tion of its diesel par­tic­u­late fil­ter (DPF), caus­ing the ex­haust to block even­tu­ally.

A de­cent di­ag­nos­tic tool is also use­ful to in­ter­ro­gate the var­i­ous func­tions of the car, to en­sure that no faults have been flagged-up. Most com­pe­tent garages can carry-out this pro­ce­dure, but it is also worth do­ing it from home.

Like any tool, di­ag­nos­tic equip­ment varies in price and it's worth seek­ing out the best value hard­ware and soft­ware, based on your car’s age and the DIY tasks you might wish to at­tempt.
