With over a million new diesel cars being registered within the UK in 2017 alone, it is clear that diesel isn’t going away any time soon. In fact, 2017 registrations will soon be out of their warranty period and reaching the aftermarket. Despite new diesel registrations dropping by almost 30% in 2018 as reported by Autocar, there are still a substantial number of diesels entering the roads.
With this in mind, it is important that garages are able to service them appropriately. Carwood looks at some common issues associated with diesel system failure.
The two most common issues with common rail diesel part warranties are fuel contamination from water or particle ingress, which can lead to misdiagnosis. This is also referred to ‘diagnosis by replacement’, which can result in warranties being rejected, so is best avoided when possible. It is important to use appropriate diagnostic equipment and follow manufacturer guidelines.
To identify the failure point accurately, it is good practice to check the following 5 points initially:
If further clarification is required, Carwood’s dedicated Technical Helpline is available on 0844 576 2524.
Carwood has an extensive offering of components suitable for diesel engines. Sample highlights include:
Carwood advises installers to call their Technical Helpline for assistance before returning parts. Carwood common rail pumps and injectors carry a 2-year warranty; if a ‘no fault found’ verdict is returned, Carwood may be able to retest and reseal the unit to be fit for resale. At the time of publication (August 2019), the retest fee is from £17.50 for injectors and from £50 for fuel pumps.
With diesel vehicles accounting for over 45% of vehicles in the UK, it is evident they will remain in service for many years to come, thus it’s important that garages are prepared to service them.
