Diesel Particulate Filters (DPFs) failures don't start with a loud alarm. They creep in as subtle shifts in differential pressure and regeneration behavior. In this transit predictive maintenance case, the vehicle's computer never warned of a DPF problem during the lead-up, but WatchTower flagged it one week before a diagnostic...

For transit fleets, aftertreatment surprises mean road calls, missed pull-outs, and expensive parts swaps. One frequent culprit: partial Diesel Oxidation Catalyst (DOC) face plugging that quietly slows DPF warm-up until the filter overloads. In this case, WatchTower, Diesel Laptops' predictive maintenance tool for transit buses, caught the problem days before any fault...

Introduction: Turn Hours Into Minutes When a commercial truck flags a fault, every minute counts. Traditional diagnostic workflows, such as referring to manuals, searching across OEM systems, or calling suppliers, can stretch into hours, extending downtime and eroding your bottom line.But downtime isn’t just an inconvenience; it’s a full-blown profitability...
