Hi all,

I have a 2000 740i, which has covered 95,000. It had a new tranny installed
2,500 miles ago, and has full service history, and still under BMW warranty.

I have only just bought the car, but have owned 2 740's before, and a 745Li.

With the window down in the drivers seat, I can hear a feint 'tick' from
under the bonnet. It seems to be linked to the engine speed.
Is this normal??

Also, there seems to be a drone / whine which appears to come from the auto
box, or the torque converter. This seems particularly loud to me when on
overrun (ie. costing in from a high speed, with the engine essentially
idling, or engine braking).
I have never been aware of this on my previous 740s but it may have been
there.... ??? I never noticed it on my 745 either.

I may be being too sensitive, as the BMW warranty is about to expire, and I
don't want any large bills, if I can avoid them. In my experience the
dealers aren't much good at detecting things that are problematic, they can
only tell you things once they have fully failed.

Any input appreciated.

Thanks


Paul
