Forté's Technical Helpline receives over 300 calls per month. This blog shares solutions for garage workshops on common driveability concerns that can be quickly and effectively treated. The vast majority of those identified are caused by fuel and oil borne contamination formed by natural degradation or via the combustion process. This is a fact of life for internal combustion engines where fossil fuels and oils are used.

Problem with a VOLKSWAGEN POLO 1.4L TDi 2008 166k
Lack of power due to engine running in limp mode, engine management and Diesel Particulate Filter (DPF) warning light on.
Fault code stored for DPF blockage, unable to carry out regeneration of DPF due to excessive soot loading.
The fault was cured by removing the DPF to manually clean using Forté DPF Off-Car Cleaner as per instructions, carrying out an oil & filter change and adding Forté Diesel Specialist Injector Cleaner, Forté Advanced Formula Diesel Treatment, Forté DPF Cleaner & Regenerator and Forté Diesel Turbo Cleaner into the fuel tank.
The vehicle was then taken on an extended road test with the engine power and performance was restored.
