Air & Fuel filter replacement intervals and cost
My 335d is going to dealer on Monday for oil service. As it is over 4 years old it qualifies for the £139 offer which seems pretty decent.
Looking in the manual it quotes needing air and fuel filters replaced at the third oil service which this will be. Question is what mileage intervals should these be replaced, my car is very low mileage for its age, only 40k for nearly 6 years old. Expect the dealer to recommend replacing these but are they really due?
Also anyone any idea of costs so I can be sure the dealer is giving me a decent price. I expect I can easily do the air filter and buy from ECP or similar, probably would let the dealer do the fuel filter.
