As new to driving an automatic I assumed the whirring engine noise might be 'normal' but is now a cause for concern as it has been 'diagnosed' as possibly 1) from the turbo, 2) a bearing eg alternator, in the early stages of collapse.
My own feeling having perused the net, is a possible fault in the diesel pump supplying the common rail (is the pump electronic or mechanical off the camshaft?). Whirring starts at various revs, low when started, at 1500, 2000 and over on acceleration - and appears to stop when the rail is 'charged'.
Meriva bought s/h 6 months ago with 15100 miles on the clock, have only done just over 2000 on short runs, am pleased with it but want to make sure of reliability on long journeys. Any Ideas?? MHB.
