My 1999 Mercedes S500 has started making noises on starting up. Presumably the air suspension. Can anything be done about this and does it make the car unsafe? It only lasts for about 10 seconds and then all seems quite OK

2010 Merc E220 Diesel, over past few months driving along

2010 Merc E220 Diesel, over past few months driving along and suffer complete power loss. Engine always starts no problem, sometimes happens 2/3 times in short period and then yellow light comes on, engine malfunction. If you then start/stop engine about 4 times light disappears. Had it in garage before Christmas but could not diagnose problem. They poured some fluid into fuel tank. It then happened again twice in March and then last week. In garage again where they were able to get some sort of message on diagnose equipment. They said it was likely the fuel pump in the deisel tank which was replaced. Three days later same thing happened again driving along and loss of full power.
