N47 2.0 diesel and timing chain failure with auto gearbox?
Discussion
I test drove an E60 520d with the LCI auto gearbox and noticed how easily the engine revved beyond 3k rpm from cold, even on part throttle. This had me a little bit concerned as I have been driving my E92 320d manual with kid gloves, never taking it above 2k rpm for at least the first twenty minutes of every journey!
There was also a shudder that was coming through into the cabin from the engine bay, similar to what you might hear if small loose objects were left in the centre console. The noise was only there when the engine was idling. I don't experience this in my own car.
The car I test drove had the timing chain replaced by BMW November 2013; could it be on the way out again??
Should I be considering manual E60s only given the auto gearboxes eagerness to use the rev range from cold?

Best way to listen for a shagged chain is to crouch down by a front door, facing forward - listening for the shhh -shhh-shhh-shhh noise.
I wouldn't touch an N47. A 520d E60 is an expensive alternative to a Mark 4 Mondeo. 525d Auto is the way to go.
You also forget many will dismiss the the MKIV Mondeo as it is "only a Ford"; aka the badge is perceived as being rubbish.I wouldn't touch an N47. A 520d E60 is an expensive alternative to a Mark 4 Mondeo. 525d Auto is the way to go.

I'm considering the 525/530/535d now, I see Hexagon have a 535d...for £18k
Had a 2007 X3 with the N47 engine (177) from brand new. 5 years old (just) with 110,000 on the clock and the timing chain snapped. Had full bmw service history from new at the local dealer and both BMW UK and the dealer didn't want to know.
Was running perfect and there was no funny or strange noises my wife parked it up one evening, went to start it next day and it was just turning over and wouldn't fire up. It was turning over quite quick, obviously no compression was the reason for that but there was absolutely no warning. When I phoned round to get some prices for repair, there were specialists who claimed to be doing three a week!!
Stay clear unless you want a big bill.

Going from what the original poster was saying - the vibration is likely to be from the air filter housing meets the ducting from the front - just touch the top of the housing and it will stop the noise - an e60 trait that is fixed with some fabric tape on the inner edge of the joint.
Also, some of the quality enhancements that were done have been known to fail - especially when just the top chain has been replaced with an open link one. Seems to be more down to the quality of the tech doing the work
