    I have looked at numerous images including this

    but mine looks totally different, is this the MAF on mine?
    If so can anyone point me to the removal process (to clean) on my particular engine

    Thanks, not sure i fancy that pressure hose clamp, i can see it but looks a pig. Apart from that looks fairly straight forward.
    I just disconnected the sensor run the car and it idled smoothly, so i'm guessing this is a job that needs doing. I don't think i,ll even get my hands down the back of that box.
    In that thread, someone asked can you not just squirt it with the thing in situ with the airbox opened up? would be easier want to try and clean it

    I guess you could try squirting in some cleaner via an aerosol can with the lid off the cleaner box but its likely only a temporary fix. In terms of removal one approach would be to sacrifice the large bore connecting rubber boot by cutting it if that top clamp won't come off- mercedes will have a custom tool for the job! and then replace the clamp with large jubilee clips top and bottom on a new rubber boot part no A2710920596 priced around a tenner from MB. [CHECK PART NO AND AVAILABILITY WITH THEM FIRST!]

    It's interesting that in this video from 6:02 to 6:32 he is saying don't need to remove bottom one. Can top one not be removed?

    Yes it can -but as the guy explains-easy only with the specialist tool- even then he changes the upper clamp to a worm drive [jubilee] type clip. The only reason you would remove the bottom one is if you damaged the rubber boot [ by accident or deliberately] and had to replace it. Even with the replacement worm drive upper clip which he obviously favours he uses a flexible extension drive to tighten it up.
    So you can risk fiddling that top clamp off without the correct tool and with a bit of luck you might just do it without damaging the rubber boot but it would appear a good idea to change the clamp to a worm drive type.
