A lot of smoke when in reverse
This afternoon I drove my car in reverse for half a block (forgot my cell-phone) laying a nice white/blueish smoke layer in the street.
Normally there is hardly any smoke, besides in the mornings after a cold night. Any concern, thanks. |

It just may be that in reverse the smoke blows towards the front and you notice it more than if it was blowing away from you.

That's a funny one, but no, I always check my rear mirror for smoke. Never noticed anything.
I think if you are right I would get the finger much more often. |

the smoke probably goes away when it's warmed up,so rdanz is probably right dought if its any worry both my 240 and SD do the same if I dont put additive in them often........

Check the vacuum modulator. When it fails, trans fluid get burned up in the combustion process= hence white smoke.

Maybe on a gasser but a MBZ diesel doesn't use manifold vacuum to operate the shift modulator. Consequently, there's virtually no way for transmission fluid to get to the combustion process If the modulator failed, I suppose ATF could make it to the intake tract via the ALDA/overboost tubing on a turobcharged engine but then only if the turbo had crapped out and you were coasting down really long grades. I would also imagine that you would have other systems failing from ATF-plugged vacuum lines too. ie door locks, engine cut-off etc. Actually, I think these cars smoke a lot more than we realize. It simply isn't all that apparent in the mirrors until you back up or drive behind a diesel and can actually see the smoke being generated. Neither of my diesels are what you would consider smokers yet, I'm always surprised by the amount of smoke/haze generated behind SWMBO's 300D whenever I drive behind it or see it accelerate away from the house.
