    I am having an issue with my E220cdi (2009) faults – EBV,ESP,ABS not functional also run flat indicator not functional coupled with the interior lights not coming on when entering the car. I took it to a Mercedes specialist who said it was either a pre fuse or wiring or the ABS unit itself. The Abs unit is running all the time unless I disconnect it- which I do. I can find the rear pre fuses but where on earth are the front pre fuses? I have looked under the passenger’s foot well and also the drivers-still can’t find it. Any and all suggestions welcome.

    You need to remove the drivers side carpet and obviously the throttle pedal. Up front there is a black plastic cover with the pre fuses underneath

    A voltmeter at the module is sufficient to test a pre-fuse.

    You don't dismantle it. There is one 10mil nut holding it on, and a plastic cap to pop off in order to access the 10mil nut

    (Re abs constantly running) I have had this with a ml430 and it was the abs unit, it does really need to get checked to confirm though.

    Thanks for your help & advice, I will take a look at it tomorrow and hopefully find the blown fuse.

    ABS sorted

    Here is an update on my ABS troubles.

    I eventually gave in and took my five year old E220 to Hughes of Aylesbury this week, after nearly five hours being diagnosed they told me it was definitely the ABS pump. Cost of replacement was £1700!
    They also told me that they had put a request into Mercedes Benz UK for a contribution as the pump should last the lifetime of the vehicle, a tense hour passed then a call to say that Mercedes Benz UK was footing the bill in its entirety- phew what a relief that was I can tell you. Special thanks to Ian Donald at Hughes of Aylesbury.

    That's a good result, worth a visit to the stealers then.
