Low Exhaust Gas — ASU

To the necessary special studies of the exhaust gas (ASU) we have been accustomed for a long time - cars that have been riding on their wheels for over 30 years should be exempted from ASU. For new vehicles, the ASU badge is valid for three years, after which it must be inspected twice a year. ASU is produced by repair shops with the appropriate equipment, as well as DEKRA and TÜV. For measurements, the exhaust system must be «sealed» and the suction system is in perfect working order. If your V6 regularly uses the services of a workshop, then ASU is automatically performed there.
