Hi,
Have uk spec 2004 745i (e65) and have noticed a loud chirping noise, a bit
like a slipping fanbelt when the engine is hot. At first, i thought it was
fanbelts or pulleys at front of engine but today removed the front lower
engine cover (plastic), lower engine cover (metal - where oil filter is
situated) and lower gearbox cover. On the underside of the gearbox /engine
there are a series of rubber grommets which can be removed and the
flywheel
can be seen spinning. The noise seems to be coming from that region. It
does
not make the noise with the engine cold and when the engine is revved, the
noise disappears until the revs fall to about 1500.
I have also noticed that sometimes the car is a bit slow to pick up from a
standing start but frankly, i am not impressed with the gearbox
performance
at all which seems to show a lot of the pick-up problems experienced by a
lot of drivers on BMW e65 forums. Could this be a low gearbox oil problem,
I
had similar problems (but no noise) with my previous e38 although i did
have
an obvious oil leak. There doesnt seem to be any trace of oil leak on the
e65. I was wondering if that when the engine is revved the oil is being
pumped around whatever is making the noise. Anyone any experience?
Many TIA
Paul
