Hi All am a newbie so if this is in the wrong place I do apologise.

I have owned a 163 ML 270 cdi since Jan 2006 and it has been 100% reliable so far over the 75,000 miles I have added!! Now has 122,500 total

I am more used to mending MGBs with a hammer, rag and can of WD40 so please bear with me.

Advice please

On setting off and when vehicle is cold the car is doing a good impression of a Police siren. The note rises with engine speed but is not matched to it. I imagine it to be the alternator or scare myself with thoughts of bearings in the Turbo any ideas?

Second problem is when the car is hot the auto gear changes are just like "riding the clutch" in a manual car. As the gear goes to change the engine revs rise as if clutch engaged and the throttle opened.

Thanks in anticipation of members help

Hi, and welcome....

The whine could be caused by a partly restricted oil filter in the gearbox........you need to renew the gearbox oil and filter, this may also rectify the 'flaring' that you are getting between gearchanges.

Do a search on this forum, there are plenty of posts relating to tranny oil changes.....it is a fairly easy diy job.

Thank you for the reply, I will do as you suggest.

Also try running the engine with the belt off to elimnate the power steering, alternator etc.
