How do you choose the right NOx sensor?

Diesel vehicles often have two NOx sensors: one before and one after the SCR catalyst. They are not interchangeable. Always check the OE number on the connector or in the parts catalogue, plus cable length. Unsure whether you need upstream or downstream? Send the VIN and we will identify the part.

When is DPF cleaning worthwhile?

• Poor performance or rising fuel consumption
• DPF warning light on
• Forced regeneration did not help
• The ceramic is still intact (no melt or cracks)

If the filter is mechanically broken, order a new DPF.

How it works

1. Ship or drop off in Nazareth or Brussels
2. Professional cleaning with industrial equipment
3. Check and return

How do you order the right injector?

The injector has a unique number. Always order on that number, not just make and model: common-rail injectors are calibration-sensitive. After fitting, the correction values (IMA/IQA/C2i/C3i depending on brand) must be written into the ECU. Our technical team will help match the part. See also Faulty diesel injector?
