We flush the DPF filter with two specialist chemicals that are designed to remove soot. We then add a fuel additive to aid with the DPF regeneration and emissions.
As part of the process we will do full diagnostics to check the cause of the fault where we analyze the DPF data and check the DPF pressure, soot and ash level. Once the clean has been completed we re-analyze the data to confirm that the clean has been successful.
On diagnostics we will then ask the vehicle to do a forced-regeneration of the DPF, ensuring the vehicle is able to do this and that the DPF is clean and operating as it should.
As part of the price, we will also do a boost leak test of the engine and DPF pressure pipes. This test is to ensure there are no engine boost leaks. Also to check that the DPF pressure pipes aren’t split.
