Impending problem of just a glitch?

[AMGeed]

Driving the S204 back from the workshop after having a brake fluid leak sorted, the car lost all power when climbing a steep hill.
Not much better on the flat, it was no acceleration and little power. I parked up and put my code reader on the car to see P0100, Mass or Volume Air Flow A Circuit.

I cleared the code and went for another drive. 30 miles later, the fault hasn't returned, touch wood.
Am I looking at an impending MAF sensor replacement or maybe an air leak from under airbox (M271 engine) or was this a one off occurance?
Anyone else had this happen?

I have had things like that with the W204, I used to own.
In my Opinion, Mercs are fickle things sometimes, and you may find it was a one off glitch?
Maybe you annoyed it by putting it the workshop, or are the Batteries ok, low voltage can lead to all sorts of issues, that dont actually exist.

Didn’t you have something similar a few months back?

So after just over two years of ownership, I have the first problem with the engine. (2009 S204 180k with M271 engine)
Parked up last Fri evening after a non fault drive. Started today and pulling out into traffic I noticed a distinct lack of acceleration,
Coming to a halt in traffic, the revs were fluctuating between 500 and 1k rpm and taking the foot off the brake it was jerking as it crept forward.
Deciding all was not well I turned to return home and on pressing the throttle, the revs rose but there was no power at all and the engine noise increased considerably.
On the 3 mile trip...

That was a hose that detached itself from the throttle body. Not connected to the latest issue Will.

A few months ago my glc went into limp mode on a cold frosty morning after 500 yards , no fault codes .
Parked up and switched off ,then back on. It's been ok ever since . If it were something continuous I'm sure we'd all notice . Id put yours down to a glitch for now . Until you reach that point.
