Prolonged DPF restriction can place extra strain on the system

AutoChip inspected a 2008 BMW 318d with a 2.0-litre diesel engine and around 316,000 km on the clock. The owner reported that the car had become difficult to drive. Inspection of the original particulate filter showed that its internal core had melted.

The exhaust sensors were still in place, but diagnostics also found a lambda sensor fault and an EGR problem, along with errors in the charge-air system. Prolonged high exhaust backpressure can put additional strain on other exhaust components and the turbocharger, so these symptoms should not be ignored.

The video shows the damaged filter and discusses the planned scope of work: DPF and EGR software changes, a Stage 1 calibration and removal of the filter. It does not show the final software write or post-repair power measurements.
