All diesel engines post 2008 are fitted with Diesel Particulate Filters (DPF) located in the exhaust system. Theses filters basically trap soot/particulate that is a by-product of diesel combustion but allow gases to pass through. They are designed to regenerate or clear themselves of this soot when it reaches a certain level or capacity. However if there are faults in the engine management system or the vehicle does a lot of stop start driving it becomes impossible for a regeneration to occur and can lead to a very costly repair EG: New DPF for a 2008 Audi A4 is approx. E 1500. DPF for a Hyundai Santa Fe is approx. E 4000.
The 2 most common causes of DPF failure are
- Poor quality diesel (of which there is a lot of )
- Incorrect or inferior engine oil being put into the vehicle at the time of service.
Unfortunately at V.A.S.S. Motor Works we cannot do anything about the quality of the diesel, but we can guarantee that the engine oil we use cannot be beaten. The oil we use is Mobil both for Fully Synthetic (modern vehicles) and Semi Synthetic (older vehicles). It meets and in most cases surpasses all vehicle manufacturers’ specifications and is of a higher grade than most main dealers use.
