Hi everyone,
I am wondering if someone had a similar problem. With no previous signs my 2001 ML270 suddenly cuts off on the highway. (It had no signs of any problems before). A few attempts starting the engine it starts, but had no power at all, I managed to get to safe place, but it heavily smokes with white-grey smoke. Diagnostics shows a few stored faults but only one current: "P0100 Hot film MAF sensor (B2/5) Supply voltage problem (too low)". I already ordered it, but it looks like it is not the only problem, cause according to a few posts here even if it is disconnected car suppose to drive on lower power. In my case it is pretty much impossible.
What makes me additionally suspicious that it is not the only MAF sensor is that the car has never make any smoke before. Exhausts gases were always pretty transparent.
I have already bought MAF, but it takes about 2-3 weeks for it to get to Australia. I am wondering if any suggestion what should be checked more, in order not to waste to much time in waiting for consequent postages.
After careful inspection I found that a vacuum pump makes strange grinding noise(it is different from normal). It is especially noticeable when engine just stopped. Could it be an additional problem?
Could anyone give some advice which part should be tested, please?
