ticking noise from under dash when decelerating thru 75 - 70 - 65 mph when
de-clutched and aircon off, tick tick tick tick - its driving me nuts nuts
nuts , trims been checked, hearing aokay? noisier when weather cold,
I have a ticking noise in a V70 T5 that happens when braking down from
fairly high speeds and is more pronounced on a progressive slow down
on a downhill slope. The noise appears to come from somewhere in the
back and can be heard at around head height from the driver's seat.
The noise obviously does not come from anywhere at the height it
appears to come from but is reflected from somewhwere else which may
be your case as well.
Although the driver's handbook makes no mention of my car even being
equipped with any form of EBFD (Electronic Brake Force Distribution),
it is that which is causing the ticking. My car is fitted with STC
(Stability Traction Control) and nobody seems to know if EBFD is
fitted only with STC or with others as well but the ticking noise is
the back wheels sending pulses to a controller to make sure that the
rears do not lock up when most braking force is on the fronts.
I hope this makes some sense to you and avoids the need for three
visits to a dealer that another poster paid for with no result.. When
asked, dealers return a blank expression when asked about EBDF but it
is definitely fitted on some models and the pulsing ticking which is
annoying is just the various components doing theiir job.
