The Independent Garage Association (IGA) have sought to clarify the upcoming change to MOT which will see a DPF check added from February.
“We have spoken to DVSA, and they confirmed this check is planned to be implemented into the MOT test in February 2014”, said Stuart James, Director of IGA. “Further details and fail criteria will be published in a Special Notice at the end of January 2014.
“The check on the DPF will initially involve a solely visual inspection for presence. A missing DPF, where one was fitted when the vehicle was built, will result in an MOT failure.
“In the future, DVSA may bring in additional checks to counteract the situation where the internals of the DPF are removed but the original casing remains.”
DPFs need regular regeneration, when soot is burnt away at high temperature. Unfortunately, depending on how the car is used, these soot deposits can accumulate causing problems. Removal services, which typically promise increased power or fuel economy, put the vehicle outside of the strict air pollution standards it is designed to meet.
