MEYLE‑ORIGINAL DP sensors are manufactured under ambient air conditions in order to ensure that these highly sensitive electronic components meet the most stringent quality standards. Integrated into the exhaust branch, the sensor measures pressure levels before and after the diesel particle filter. Based on the difference in pressure, the system determines the level of filter contamination and initiates the filter regeneration process when necessary. If the sensor fails to function correctly, the filter runs the risk of not being regenerated when it is required, which may lead to irreversible filter clogging. This in turn can seriously damage the turbocharger. This is why a defective differential pressure sensor needs to be replaced immediately. Sensor damage is signalised to the driver by means of a control lamp flashing on the dashboard. Changing the diesel particle filter also requires the differential pressure sensor to be replaced.
“In recent months, we have seen an increase in the need to replace and repair exhaust sensors used on diesel-powered vehicles”, says Dominik Overman, Head of Electronics & Sensors at MEYLE. He explains that it is not always necessary to replace the complete particle filter assembly – in many cases, replacing a single sensor can save the workshop and the car owner a lot of time and money. “We have taken a strategic decision to develop our range of sensors for the exhaust branch by adding high-quality components, all of which are manufactured to OE specifications. We want to continue along the successful path on which we set out when we chose to add exhaust temperature sensors to our product range, a decision which was based on our philosophy of providing our worldwide customers with products they can safely rely on.”
Currently, the range of MEYLE‑ORIGINAL PD sensors caters for 26 million vehicles registered the world over. With more additions planned for 2018, MEYLE will strengthen its position in this growing market segment while doubling the coverage of its product range, which will then be catering for up to 50 million vehicle applications worldwide.
