[?]So now it's a few years later since the original post. I just bought a 00 E55 with only 40K miles on the clock. Have there been problems with the MAS on these models, or are these isolated incidents? And, to answer the original question, I believe 550 per year.
Just assume you will be replacing the MAF in around 20k miles or so. Mine kicked out at just over 78k; it gave me just enough range to drive home from Munich to London, and then once it was parked in it's own garage slot and the mechanics were coming to get it, that's it - no chance of starting again.
The MB 5-speed transmission isn't that long-lived either - and most annoyingly, it fails in a quite sudden and un-signalled way. If it takes more than a second to shift from neutral into drive and you can hear "ringing" or circulating noises sitting still with your foot on the brake then it only has a few more shifts left!
I haven't felt any sign of that yet in the 55 - I'm hoping that this transmission is built differently to the one in my 43, which doesn't audibly back off the throttle on upshifts like the 55 does.
I was told by a AMG fanatic that 500 per year 1999 to 2002 were imported to the US.
My 00E55 is more reliable when compared to the other five MB vehicles I have owned over the last ten years. 2-300E 1-400E 1-C280 and 1-E320
