Engine emission control parts.
Vehicle emissions are tightly regulated and are taken into account during the design of a vehicle and measured when the vehicle is undergoing an MOT test. Periodically the rating for emissions are revised so that new targets can be met. These ratings are listed as Euro ratings (i.e. Euro 4, Euro 5 etc).
There are different components on the engine that are used to reduce emissions so that these targets are met. Here are some examples:
EGR valve
EGR valve cooler
Swirl flap adjustment motor
Pressure converter for exhaust control
How do I choose the correct engine emission control parts?
Emission control parts such as EGR valves are specific to the engine so it is important that when replacing them that the new part is compatible. One way to make sure the replacement part is correct is to obtain the part number from the part that you need to replace and compare with the parts listed for your vehicle.
If you are unable to obtain the part number here are some factors to consider:
Euro rating (i.e. Euro 4, Euro 5 etc)
Engine code
Vehicle manufacture date (this is not the date the vehicle was registered but the date it was made
Engine number sequence (up to or after as specific number/letter
VIN (chassis number) sequence (up to or after as specific number/letter
What brand of engine emission control parts should I choose?
Brands such as Bosch and Pierburg manufacture emission control parts for the original car makers so these brands are premium. There are other makers of high quality aftermarket parts of the highest quality that meet or exceed the original specifications. Brands such as Blue Print, Febi, and Lucas offer long warranties which show they have confidence in their products. Often the premium brands are more expensive so the choice largely depends on your budget and if you prefer a particular brand name.
How can I tell my emission control parts need replacing?
OBDII (on board diagnostics) tools should show an error code that would indicate which part is faulty. If you are not sure if you have an issue with one of the emission control parts we would always recommend that you have your vehicle inspected by a qualified mechanic to receive an accurate diagnosis.
Some of the symptoms of failing emission control parts may include:
Vehicle fails the emissions section of the MOT
Increased fuel consumption
Strong smell of fuel
Check engine light is illuminated while engine is running
Less power from the engine
Engine does not run smoothly
Excessive smoke from the exhaust
