Hi All

I thought I'd post my thread in UK section given the majority of the BMW members are diesel owners.

I drive a 2011 E90 320d LCI, only done 6000km so far.

My 320d has recently starting to generate this "cranking/vibration noise" between 1500rpm to 2000rpm on 1st or 2nd gear, most obvious during a cold start or when the engine is under stressed like going up hill from 1st to 2nd gear.

Once I revved past 2000rpm, the noise would magically disappear. Already booked in for a check up at the BMW dealerships under warranty repair.

Is this normal at all? What do you reckon it is the main cause? Exhaust, engine suspension, interior trim?

Thanks
