This is not covered under warranty.ĭ) If the coil and engine management light is on with loss of power, ‘limp home mode’ will engage with a maximum of 3000 RPM. For example ‘Drive for 20 minutes at a constant speed of 65mph’.Ĭ) If the DPF is not regenerated at this stage and fills to over 90% or 45g, the DPF will need replacing. a) If the DPF light comes on (see image above) this means ‘regeneration’ is needed.ī) Once again, read the handbook for instructions.The sequence generally consists of the following steps:
The majority of vehicle manufacturers have the same warning light sequence but you should always check the vehicle handbook to be safe. It is extremely unusual that a DPF will fail on its own (the problems are usually upstream or to do with the actual system) so this is where the EEC DPF tool becomes a necessity.

There does however seem to be some confusion as to why a DPF could over-fill and how to diagnose faults. As such, the aftermarket is missing out on an opportunity to increase their sales and profit margin because DPFs are a high ticket product. The OE manufacturer warranty does not cover ‘over-filling’, as this is regarded in the same way as oil, fuel or air filters – the warranty only covers mechanical failure. This varies with each vehicle manufacture (for example Ford requires replacement at 75K and BMW at 150K) and main dealers account for the majority of DPFs fitted within our market. The DPF is a filter that removes particulates and soot/carbon from the exhaust gases and is a serviceable item that needs to be replaced at the end if its life. We contacted a diagnostic tool company and discussed the opportunity of becoming our partners in a venture to create a specialised hand-held DPF diagnostic tool.Īfter many months of hard work collating all of the data required to deliver an easy-touse, hand-held solution, the EEC DPF Reset Tool was born. I was staggered at the lack of DPF knowledge, especially the procedure regarding installation, encountering answers such as: “We regard it as a main dealer product” or: “We need specialist diagnostic tools”.ĮEC subsequently decided to eliminate one of these major objections. Last year, on my visits to various customers, I made enquiries about the general demand for Diesel Particulate Filters.
