Dots mark end for fake parts

The dangers for innocent motorists unwittingly buying dodgy car parts could be stamped out - thanks to sophisticated new technology

Auto Express Car Reviews

It can check the authenticity of genuine components by reading microscopic patterns etched on to them.

Staying one step ahead of the forgers, tiny dots will be marked on the new parts as they are manufactured. These can be scanned at any time to check for counterfeiting.

Customs officers can test them at border crossings, car makers can check before the parts reach the production line and trading standards inspectors can follow up at high street shops and markets.

They will ignore seemingly genuine packaging and labels, and use a scanner beam to measure the minia­ture markings on the part itself. If the pattern of pin-pricks doesn't match the one stored on a computer database, the device - called the Simatic HawkEye - will spot the difference.

The fake part can then be removed before it causes any trouble. It's esti­mated that up to 10 per cent of car components on sale are counterfeits masquerading under trusted brand names. In the past, authorities have seized fake suspension parts, brake pads and discs, and even steering linkages, all of which could cause a fatal crash if they failed.
