Cabin Air Filters

The cabin air filter is responsible for cleaning outside air entering the vehicle. Because up to 100,000 litres of air can be blown into the vehicle’s interior in less than an hour, it can easily become clogged with debris. Unfortunately, a blocked cabin filter will not be effective, resulting in a below-par heating and cooling system, and causing the air inside the vehicle to become more polluted than the air outside up to six times more. Similarly, bacteria and fungi can accumulate in the filter, leading to unpleasant smells in the cabin. Fitting a high-performance cabin filter, such as Delphi, is essential in eliminating these harmful pollutants and odours, safeguarding both you and the air conditioning (A/C) system.

High-performance media

All our cabin air filters use a high-performance, non-woven fabric to eliminate dust, pollen, bacteria and exhaust particles, amongst others. The specially designed filter fabric contains up to five individual layers, removing near 100 percent of harmful pollutants.

Enhanced protection

Over time moisture can build up in the filter and become a feeding ground for bacteria and mould. This can then spread into the lines of the HVAC system, where it emits unpleasant odours. For the ultimate protection from this and other pollutants, we also offer a range of carbon activated filters. Our carbon activated filters feature the same high quality, non-woven fabric as our particle filters, with the addition of a layer of activated carbon. Sandwiched between two layers of fleece, this highly effective technology removes more pollutants than standard filters, and expels nasty gases and smells too.

How to calibrate windows on a BMW

Resource Highlights

We expect our car windows to seamlessly slide up and down with the touch of a button. So when they don’t operate as they should, we need to understand exactly why. Is it a simple fix or a substantial failure?

In this video from the experts at Delphi, we show you how to calibrate the front windows of a 2015 BMW X5 following a reported fault with the ‘one touch’ feature.

With step-by-step troubleshooting instructions you’ll learn how to quickly pinpoint the problem and fix the issue. The video covers:

• Diagnosing the fault
• Self-calibration and calibration using a diagnostic tool
• Clearing fault codes
• The equipment you need

What can cause car window failure?

It could be anything from the battery having been disconnected and reconnected, the door itself or the door module having been replaced, a blown fuse, or switch failure. That’s why it’s important to run a diagnostic test on the car.

Do I need a diagnostic tool to calibrate a window?

That depends on the make and model. If you don’t have a diagnostic device to hand, try taking the window up and down several times in succession, holding the switch for a few seconds at each end of the travel . This will carry out a self-calibration on the window, but as mentioned, this method depends on the vehicle.
