In these days of on board computers, specialised oils, specialised lubricants and engine components, vehicles are far more technical than the old Ford Escort. DIY maintenance is therefore now out of the skill set of most people.
So many trades and professions require a specialist ‘ticket’ in order to lawfully carry out work due to the genuine safety concerns – but still anyone can carry out repairs and maintenance around such vital components as steering and brakes. Mistakes can and do prove to be far more costly than leaving the repairs to the professionals.
In the KAAR network there are plenty of examples of DIY horror stories that have come through the doors. Usually it just means the owner is now up for far more costly repairs retrospectively than they would have been if they had just taken it to a professional in the first place. The real concern however is when the car gets towed to a panel beaters and the drivers and passengers go to hospital or worse. What might the cost be then?
Today’s cars have more computing power than NASA used to send man to the moon, some vehicles today have over 100 computers. Today’s mechanical technicians are trained to work with the on board computers without compromising the technology. Today’s tool kits might still have the spanners and wrenches but they also hold scan tools that can cost from a few thousand dollars to tens of thousands that the DIY repairer just doesn’t have access to. Incorrectly diagnosed faults can cost the owners of vehicles thousands of dollars of unnecessary repairs and make the vehicle unsafe for your family to drive.
