Local garage suspected ABC system was to blame, but unfortunately I didn't have time to leave it with them long enough to delve any deeper. However engine mounts need replacing, which may be some source of the vibration. They suggested worn engine mounts may even be the mysterious culprit. I am planning a move to Europe, so drove back here on the weekend. I am are going to do the mounts here and with any luck learn a bit more.
Hey Nick, I've got exactly the same symptoms with my SL. When engine is cold whining noise is very noticable, after warm-up noises disappear. I bought my SL 2 months ago and as far as I know previous owner replaced ABC pump 3k km ago and system is running very smooth (and car itself has only 40k km). However last friday I visited workshop which specializes in Benz to check condition of the whole car and they said engine and transmission mounts are almost gone and need to be replaced.Local garage suspected ABC system was to blame, but unfortunately I didn't have time to leave it with them long enough to delve any deeper.

interesting, looks you've got no reason to suspect ABC – I shall keep you posted!Hey Nick, I've got exactly the same symptoms with my SL.

I'm very curiouse if changing engine mounts will fix this problem in your case please keep us updated!
I shall suggest this to them – the whining noise I am suffering is not dissimilar to the oil pump whine you always hear on ignition...M113'K's are common for having noisy oil pumps. If yours is making this noise, it will make it without the belt on the car, which is the first thing to do.
Alternatively, they could keep guessing

A couple of garages suggested this – the local Mercedes in Italy and the local Merc specialist at home in the UK.Wow, and your local garage suggested ABC system ? How come ?
Post #3. IthankyouTransmission fluid level check would be first thing on my list.
Engine mounts, possibly
