The fuel filter that protects an expensive pump
A great many vehicles based around Beddington village and the lane up past the energy recovery facility and Beddington Farmlands are diesels earning their keep, running out onto Croydon Road and the A23 Purley Way all day. They reach 24,000 miles in little more than a year, and on those that have a serviceable fuel filter it is the single most important item in the major service. Diesel fuel carries water and fine debris, and the filter is what keeps both away from the high-pressure pump.
That matters because of what happens when the filter is left too long. A restricted filter makes the pump work against resistance, and a worn pump sheds metal particles forward into the injectors. What should have been a filter and an hour of labour turns into a fuel system rebuild running into four figures. We fit OE or OE-equivalent filters from suppliers such as MANN, Bosch or Delphi with the seals supplied, and prime the system properly afterwards rather than cranking it until it catches.
The brake fluid change is the other item that belongs here rather than in the annual service. Fluid is a strict two-year job on most cars whatever the mileage, because it absorbs water from the air rather than wearing out, and we change it completely from a sealed container in the grade your vehicle calls for, testing moisture before and after. On a loaded van that comes down Croydon Road into queues all day, it is worth having right.
Everything in the full service is included alongside those: oil and oil filter, air filter, cabin filter and the wheels-off inspection with brake measurements recorded. Allow most of the day, because the fluid change alone adds around 45 minutes and longer where the ABS pump has to be cycled. We quote in writing first, ring you as soon as it is finished and guarantee our workmanship for 3 months.
