350d knocking at 2750 rpm
Hi all,
I've had my 350d for a couple of weeks now and have noticed a knocking. I've discovered that it occurs around 2600-2750 rpm in at least 2nd, 3rd and 4th, so probably all gears. It's more noticeable under load and I feel it in the floor.
Any ideas? Engine mount? .. ?
Thanks.
Mark
