Hi all,
I have a Multijet Sporting 1.9 with 6 speed (M32 gearbox i assume), 56 plate with 75k on it. For about a year now there has been a metallic grinding/rubbing noise when accelerating. It sounds like a bearing has failed and is rubbing; i say this because whatever is making the noise sounds like it is spinning. As my revs increase the speed at which this mysterious faulty part rotates also increases.
It occurs in all gears, but sounds louder in 1st 2nd and 3rd, especially when cold (i think it could simply sound louder as there is less road noise at lower speeds.) If i rev in neutral the noise is still there but less noticeable.
Stationary, when i depress clutch and engage 1st, there is a small and slight clunk as the gear is engaged (noticeable by sound and feeling through gear stick). If i return to neutral, release clutch pedal, then re-depress the clutch and select a gear again (any gear) the clunk occurs again (95% of the time, and sometimes louder and more obvious). When i depress the clutch and slowly move the gear selector into a gear, there is a small position along that travel where if i hold the gear stick in that position (almost halfway into the gear selection), the noise disappears completely and all i hear is the engine tickover.
If i accelerate at full throttle the noise disappears once the turbo kicks in, the noise is loudest and most obvious when i accelerate at a low-medium rate (half throttle for example)
I have seen many threads about M32 bearing problems etc, however i had all the gearbox bearings replaced in November 2016, as well as the clutch and flywheel replaced December 2016, and the noise did not go away after these repairs.
Sorry for long post but ive been trying to work this out for a while and this is all the info ive collected from driving with the issue. I would appreciate any input on this post, and thanks for reading, its a very very odd problem i just cannot find a solution for anywhere.
Kind Regards
Ben
