Why does the DPF require maintenance?
The DPF captures and stores soot. Over time this can block the DPF when it needs to be emptied and cleaned. Generally, any functioning DPF can handle such blockage by itself through either passive or active regeneration.
Passive regeneration is when the car is driven at a high speed, which heats the exhaust system causing the soot to burn off into ash. However, usually, most car owners seldom drive at such high speeds, and it’s mostly limited to slow and short drives around town.
Contaminated oil can heavily damage your car’s engine; the sludge-like liquid will fail to lubricate the cylinders, causing excessive metal scraping. This will, in turn, clog the filters and choke the normal circulation.
That’s why there’s active regeneration for DPF cleaning. When the ECU detects soot accumulation over a predetermined limit – typically 45% - it injects additional fuel to induce the required heat in the exhaust system. That burns off the soot.
However, these methods are not always successful in cleaning up the DPF, which is the result of a more significant blockage. That’s when the filter needs to undergo professional DPF cleaning procedure St. Helens to ensure it gets back to working at maximum efficiency.
How to tell if DPF needs manual cleaning?
Typically, it’s suggested to avail specialist cleaning service every 200,000 miles, give or take, depending on your driving style. Nevertheless, a visible indication that the filter needs regeneration is when the DPF warning light illuminates.
It’s a bigger problem when the engine management gives company to the DPF warning light. That’s when you definitely want to drive your car down to our facility for professional DPF cleaning St. Helens.
