    Hi,
    I recently had a second service carried out on our E320 CDI estate at 31,500 miles. The garage suggested that the air filters might need replacing, so I thought they can't be hard to fit, so I asked them to supply the parts.

    Each is held in place with four Torix 20 screws, but there is so little space to work in, it took ages. I accessed the lower ones by holding a shortened T20 bit strapped inside a 7mm spanner, which in turn was strapped to a long hack saw blade to get leverage with flexibility. I then used a long screwdriver in the other hand push the T20 into the head of the screw whilst turning the extended spanner.

    I wasn't expecting them to look like this!

    Presumably there is a proper tool which the garage uses to do this and I would imagine the fuel economy will improve.

    Four years or 35k is the scheduled replacement on a C220 CDI.
    Certainly looks like yours needed changing. Why was this not simply undertaken by the garage during the service?.

    I also changed mine myself after a service and the filter was full of dirt. Garages obviously do not even lift the lid to have a look. Best done on a cold engine as well -saves burning fingers.

    They were the original filters, the car is 'high mileage' only 21 months old. I decided to do it myself to save the labour charge, I hadn't appreciated how fiddly a job it was going to be. The dirt looks like caked on soil, not oil. The air inflow must have been reduced massively.

    Are you sure, Mercedes changed mine at the first B service, 2 years old & only 21,000 miles.

    I complained when the air filter was not changed at 24k on its B service and was advised by the service dept that 4 years and 35k was the interval. It does not state this in my servive manual. I changed it myself as it was full of dust and dirt. It was only £14 so hardly a huge expense. Can't understand why it was not replaced anyway.
