The title already says it: When controlling the plugs of the motor control unit (on engine oil via cable harness) of my SL350 R230, I noticed that the grid is slightly pressed in by the air mass meter on one side and loosened by the metal frame. Size order approx.30 degrees. So about 90% are still fixed. But the edge is still on the plastic tube – so nothing can fall in there. Is this relevant or more or less irrelevant? Can you change the grid by the way or must then the complete LMM can be exchanged? [It’s a thing anyway: If I look at the LMM from my 5s, there is still a massive Kunsstoffgitter in front of the fine wire grid, you could never press anything in. Alone the whole construction and the position is already unfavourable with the SL: If you don’t store the air filter box cleanly, you quickly have dirt on the sealing ring that sits on the LMM and the dirt then very quickly directly on the LMM and in the intake current. At 5s the LMM and the air filter If you change the filter, you will not even get close to the LMM. In any case, the opening of the SL is directed upwards and at the side of the 5 mm. If you change the LMM, you might accidentally fall into it from above … and if it is only the crust of the pimple or a hair … this is not easy with a side-righted opening. Possibly.] By the way: The pores of the grid have a diameter of about 1mm. What happens when such “brocks” are sucked in? Are nozzles then clogged?
