BMW 520d F10 (2011) - Another Post linked to timing chains
Discussion
Hi All,
First post ever - but use the information on these forums alot, it's great to have access to so much information/ experience and opinion
I'm just after some opinions really as you only have what I have written here to go by - I am trying to work out if I am being paranoid (my wallet is starting to shake!) or if in your opinion I am headed into a large bill?
In 2014 I bought a 2011 BMW 520d SE - it's been faultless over the last 4 years and is now close to the 115,000 mile marker. Its not a hugely exciting car but has taken me and the family on some long journeys (600 miles through France and back) in a really relaxed easy manner (nightmare getting in and out on the ferry though) and I've really appreciated it for that.
Over the last few weeks however on startup I am getting the dreaded timing chain rattle - it is very clattery for roughly the first 3 seconds from when the engine is first started then it seems oil gets into the tensioners and the noise is gone.
After a journey and the engine is warm I am listening intently for more chain noise, but it's difficult to hear anything over the cacophony of shakes and rattles (I think the engine is quite gruff at tickover). I can definitely hear the timing chain in the overall orchestra of sound but it's not chattery like some of the U-Tube vids.
The car has (roughly) 12,000 mile oil changes with the BMW long life oil as I dont like the thought of running up to 20,000 miles between services but I can't imagine at the start of it's life this was the case as it was an ex-company car prior to my ownership.
What are other peoples experiences? Is this possibly the beginning of my troubles or have you had similar experiences and 'x' months/ years later still have no trouble.
I am particularly conscious of this given the location of the timing chain and I dont know that I want to re-invest in the car to the tune of having chains/ guides/ tensioners etc changed

This a 2012 car http://www.babybmw.net/forum/viewtopic.php?t=45004
The last post "Just took my 2013 120d (~37k miles) to the dealers because i could hear a faint "swish swish" sound under idle. It was of course the timing chain and BMW is going to change all the parts and pay the expenses 100%. It was a nice gesture as the car has already run out out of warranty a year ago.
So it seems the problems is still there also in these "newer" cars. " unquote

Long term fix would be to fit revised parts - including new thicker chain - not cheap. Also adding Ceratec may help with the chain drive.

I would also cut oil intervals to half of what the board computer says (adding Ceratec with every oil change - regardless of the 30k miles claim).
