Additive/PATS/Eolys

Service Description

Some vehicles use a fuel additive system (PATS, Eolys or Cerine) to assist DPF regeneration. If your additive tank runs dry, the DPF cannot regenerate properly, leading to a blocked DPF and warning lights. We refill the additive fluid and reset the ECU counter to restore normal DPF function. Essential maintenance to prevent costly DPF failures.
