Car engine trimming has been done for many years. In the past two decades, so-called chip tuning has come full circle. Simply put, change various settings to get more horsepower and more torque. This can also affect emissions and fuel economy.
The Norwegian Public Roads Administration and the police today took action against two chip-tuning actors. The objective of the action was to find out if there was an illegal operation of the workshop.
– Over time, we have seen an increase in the number of players offering vehicle trim and disconnection of engine cleaning systems for the exhaust. This is work subject to approval, and requires companies to be approved and comply with current requirements. It is important for customers to be aware that this type of modification can lead to the use of the vehicle being illegal, says Jon Molnes of the Norwegian Public Road Administration.
Must be approved
Two businesses in Vestfold and Telemark counties were inspected.
– Now the police will investigate the case against the illegal operations of the workshop. Those who have modified or modified their car at these two companies can be summoned for an inspection by the Norwegian Public Roads Administration. Then the car owner must present documentation that the vehicle is in good condition, Molnes says.
For a trimmed vehicle to be legal, it is a requirement that the vehicle is approved at one of the Norwegian Public Roads Administration traffic stations after the trim. The new effect must be written on the vehicle’s card.
It can be fun and very expensive
– Customers are deceived
These days, there are quite a few companies across the country offering so-called chip tuning, which means you have to go in and change the electronic engine control. The purpose of this is to get more power out of the engine. The downside is that this can also change the engine’s exhaust.
– Customers are misled when unapproved players claim chip tuning is legal and must bear the consequences. It is the owner of the car who is in charge of documenting that the emissions of the engine are within the requirements with which the car was originally approved, says Molnes, in a press release.
Such documentation must be obtained from the automobile manufacturer or from a publicly approved laboratory.

Many thousands of vehicles

– If it is not possible to obtain such documentation, the car owner must return the engine to its original condition in an approved workshop and be able to document this when the car is inspected at one of the traffic stations of the Norwegian Public Roads Administration, says Molnes.
Many of the players offering vehicle trim and modifications do not have the required workshop approval from the Norwegian Public Roads Administration.
– Due to the scope of this type of business, we have reason to believe that many thousands of vehicles are circulating that have been cut or illegally modified on Norwegian roads, says Molnes.
Requested separately
According to the Norwegian Public Roads Administration, many of the tuning players also market that they disconnect or remove cleaning equipment, such as particle filters, that most diesel cars have.
– Particulate filters need to be maintained and in many cases replaced when the car is a few years old. It has probably been tempting for many to simply unplug this cleaning kit, rather than do a more expensive repair. The consequence, however, is that the exhaust gases will be much higher than the car is approved for. When we discover that the cleaning crew has been disconnected, the car owner will be informed that they must reconnect before the car can be cleared at a traffic station, Molnes says.
Cars not manufactured will be requested for inspection after a subpoena from the Norwegian Public Roads Administration.
